This document is intended as a quick start guide and as a reference for the application settings and general functionality. For details on how to build ES-DE from source code and to perform more advanced configuration, please refer to [INSTALL.md](INSTALL.md).
You can always close the application immediately by using the keyboard, by default the exit key is mapped to F4 but this can be changed to Alt + F4, Alt + Q or Command Q (on macOS) using the _Exit button combo_ menu option.
Additional known issues are detailed in [CHANGELOG.md](CHANGELOG.md#known-issues).
As for display resolutions, the minimum pixel value is 224 and the maximum is 7680. This means that you can run ES-DE at for instance 320x224 all the way up to 7680x4320 (8K UHD). Vertical screen orientation is also supported, as well as ultra-wide resolutions like 3840x1440. Note that there could be some minor visual glitches when running in vertical orientation (this will be fixed in future ES-DE releases) and for the best experience you will probably need to use a customized theme set when running at extreme or unusual resolutions.
The installation procedure is just covered briefly here and may differ a bit for your specific operating system, so in case of problems refer to your system documentation.
The .deb package is intended for Linux distributions based on Debian, such as Ubuntu, Linux Mint, Raspberry Pi OS etc. Your distribution should include a graphical package installer, but if you prefer to use the command line, run the following which will install ES-DE and resolve any dependencies:
In addition to the .deb and .rpm packages covered above, ES-DE is also available as an AppImage which should be usable on most modern x86 64-bit Linux distributions. After download you may have to set the file as executable, such as this:
But in some desktop environments this is not required and you can simply launch the file by double-clicking on it using your file manager. The first time you do this you will be required to confirm that you actually want to execute the file. Running the AppImage works exactly as if you would launch ES-DE if installed as a .deb or .rpm package. It's also possible to run it from a terminal window, in which case all command line options work the same way as if installed as an ordinary package.
For a better desktop integration it's recommended to install [AppImageLauncher](https://github.com/TheAssassin/AppImageLauncher) which will add an ES-DE entry to the application menu and move the AppImage file to the `~/Applications` directory (which is the recommended location for all AppImages).
There's not really much to say about these operating systems, just install ES-DE as you would any other application. On macOS it's via the .dmg drag-and-drop installer, and on Windows via the normal application installer.
On Unix this means /home/\<username\>/.emulationstation/, on macOS /Users/\<username\>/.emulationstation/ and on Windows C:\Users\\<username\>\\.emulationstation\
**Note:** As of ES-DE v1.2 there is no internationalization support, which means that the application will always require the physical rather than the localized path to your home directory. For instance on macOS configured for the Swedish language /Users/myusername will be the physical path but /Användare/myusername is the localized path that is actually shown in the user interface. The same is true on Windows where the directories would be C:\Users\myusername and C:\Användare\myusername respectively. If attempting to enter the localized path for any directory-related setting, ES-DE will not be able to find it. But it's always possible to use the tilde `~` symbol when referring to your home directory, which ES-DE will expand to the physical location regardless of what language you have configured for your operating system. If you're using an English-localized system, this whole point is irrelevant as the physical and localized paths are then identical.
It's possible to override the home directory path using the --home command line option, but this is normally required only for very special situations so we can safely ignore that option for now.
Also on first startup the configuration file `es_settings.xml` will be generated in the ES-DE home directory, containing all the application settings at their default values. Following this, a file named `es_systems.xml` will be loaded from the resources directory (which is part of the ES-DE installation). This file contains the game system definitions including which emulator to use per platform. For some systems there are also alternative emulators defined which can be applied system-wide or per game. How that works is explained later in this guide. A customized systems configuration file can also be used, as described in the next section.
There's an application log file created in the ES-DE home directory named `es_log.txt`, please refer to this in case of any issues as it should hopefully provide information on what went wrong. Starting ES-DE with the --debug flag provides even more detailed information.
After ES-DE finds at least one game file, it will populate that game system and the application will start. If there are no game files, a dialog will be shown explaining that you need to install your game files into your ROMs directory. You will also be given a choice to change that ROMs directory path if you don't want to use the default one. As well you have the option to generate the complete game systems directory structure based on information in es_systems.xml.
When generating the directory structure, a file named systeminfo.txt will be created in each game system folder which will provide you with some information about the system. Here's an example for the _gc_ system as seen on macOS:
The primary use of this file is to see which RetroArch core the system needs, which you will have to install manually from inside the RetroArch user interface. Also the supported file extensions can be quite useful to know.
In addition to this, a file named systems.txt will be created in the root of the ROMs directory which shows the mapping between the directory names and the full system names.
If a custom es_systems.xml file is present in ~/.emulationstation/custom_systems/ any entries from this file will have their names trailed by the text _(custom system)_. So if the GameCube system in the example above would be present in the custom systems configuration file, the system would be shown as _gc (custom system)_ instead of simply _gc_. This is only applicable for the systems.txt and systeminfo.txt files, the trailing text is not applied or used anywhere else in the application.
Note that neither the systeminfo.txt files or the systems.txt file are needed to run ES-DE, they're only generated as a convenience to help with the setup.
There will be a lot of directories created if using the es_systems.xml file bundled with the installation, so it may be a good idea to remove the ones you don't need. It's recommended to move them to another location to be able to use them later if more systems should be added. For example a directory named _DISABLED could be created inside the ROMs folder (i.e. ~/ROMs/_DISABLED) and all game system directories you don't need could be moved there. Doing this reduces the application startup time as ES-DE would otherwise need to scan for game files for all these systems.
_This is the dialog shown if no game files were found. It lets you configure the ROM directory if you don't want to use the default one, and you can also generate the game systems directory structure. Note that the directory is the physical path, and that your operating system may present this as a localized path if you are using a language other than English._
As explained above, the basic logic for how ES-DE works is that it expects game files to be placed into a standardized directory structure under the ROMs directory. The location of this directory is configurable so it could for instance be placed on an external storage device or on a file share served by a NAS. The way it's implemented is via the %ROMPATH% variable in the es_systems.xml file which will always point to this ROM directory. For example this is an entry for the Super Nintendo system:
```
<path>%ROMPATH%/snes</path>
```
In theory it's possible to make a custom system entry and hardcode the path to a specific directory instead of using the %ROMPATH% variable, but this is not really supported and it also makes custom collections non-portable as the path to every game will be an absolute path rather than a path relative to the %ROMPATH% variable. So if you move your games to a different directory, you would manually need to modify all your custom collections configuration files as well as your custom es_systems.xml file.
If you really insist on not placing your games into the ES-DE standard directory structure, a much better solution is to symlink the game directories into the standard directory. In this way you don't need to make a custom es_systems.xml file and any additional emulators and other configuration added to future ES-DE releases will just work after upgrading.
This is an example of symlinking the Super Nintendo game directory on Unix and macOS:
```
cd ~/ROMs
ln -s ~/my_games/super_nintendo/ snes
```
And on Windows (you need to run this as Administrator):
The way ES-DE works is that it will always try to load any system for which there are game files available, so to disable a system it needs to be hidden from ES-DE. This is easily accomplished by renaming the game directory to something that is not recognized, for example changing `~/ROMs/c64` to `~/ROMs/c64_DISABLED`. Another approach is to create a subdirectory named DISABLED (or whatever name you prefer that is not matching a supported system) in the ROMs directory and move the game folder there, such as `~/ROMs/DISABLED/c64`. This makes it easy to disable and re-enable game systems in ES-DE. Note that the gamelist and any game media files are retained while the system is disabled so this is an entirely safe thing to do.
## Placing games and other resources on network shares
Although ES-DE does support placing game ROMs, the `.emulationstation` home directory and the `downloaded_media` directory on network shares, this can lead to serious performance problems in some instances. Especially problematic is the Microsoft SMB protocol as it offers abysmal performance for some disk operations on which ES-DE relies heavily. For small game libraries this can still be acceptable, but for libraries with hundreds or thousands of games the application startup time and overall usage will be very painful or even unusable.
A general recommendation is to place all game files and other data on drives connected directly to the machine where ES-DE is running. Even using low speed technology like USB thumb drives, SD cards etc. is generally fine and leads to acceptable performance in most instances.
If you insist on placing games and other resources on network drives such as a NAS, the NFS protocol has to be used instead of SMB as testing has shown between 10 and 30 times better performance with this protocol. Starting ES-DE with a certain game collection size could easily take minutes using SMB while it takes just seconds when using the NFS protocol. This is not a network throughput issue and using something like a 2.5 Gigabit or even 10 Gigabit wired interface will not help you as the SMB protocol has exceedingly bad latency regardless of physical adapter speed.
Unix-based operating systems like Linux and macOS ship with an NFS client built-in.
Here's how to mount an NFS drive from a NAS called _MyNAS_ on macOS:
```
sudo mkdir /private/ROMs
sudo mount -t nfs -o resvport MyNAS:/ROMs /private/ROMs
```
On Linux it's quite similar:
```
sudo mkdir /mnt/ROMs
sudo mount MyNAS:/ROMs /mnt/ROMs
```
On Windows 10 and 11 the NFS client first needs to be installed as it's not enabled by default. Open the _Control Panel_, then _Programs and Features_, then select _Turn Windows features on or off_ at the left side of the window and tick the box _Services for NFS_. It's unclear if both child items _Administrative Tools_ and _Client for NFS_ need to be selected, but it's probably safest to enable both of them.
Following this you can mount the NFS share in a terminal window as on a Unix system:
```
mount MyNAS:/ROMs g:
```
Note that the above are only examples to illustrate the general approach, you may need to take additional steps to make the configuration persistent across reboot and you may need to make other preparations. The NAS/file server also needs to be configured of course, but that's beyond the scope of this document.
In general it should be straightforward to run ES-DE on Windows. Almost all emulators are available on this operating system and driver quality and controller support is normally very good.
Just make sure to not place games or other resources on network shares using the Microsoft SMB protocol as that will lead to unacceptable performance degradations and extremely long startup times if you have a large collection. See the point above on how to setup an NFS share if you insist on placing files or other resources on network drives.
In order for ES-DE to run, graphics drivers with OpenGL support have to be installed. If not, the application simply won't start. For really old graphics cards the available drivers may not provide an OpenGL version that is modern enough for ES-DE to work, and in this case a last resort solution would be to install the _Mesa3D for Windows_ library which provides software-based OpenGL rendering. The library can be downloaded from [https://fdossena.com/?p=mesa/index.frag](https://fdossena.com/?p=mesa/index.frag) and you simply extract the opengl32.dll file into the ES-DE installation directory. Just be aware that the performance may be quite bad.
Installing DS4Windows will break controller input in ES-DE for unknown reasons. Uninstalling this software should resolve the issue. On Windows 11 both DualShock 4 (PS4) and DualSense (PS5) controllers have been tested wired and via Bluetooth and both work fine in both ES-DE and RetroArch without any special drivers or configuration.
There are two ES-DE releases available for Windows; a regular installer and a portable/ZIP version. If going for the first option, an issue is that many emulators are not shipped with proper installers that implement any mechanism to inform ES-DE where they have been installed (like adding a Registry key with their installation path). Such emulators are marked accordingly in the _Supported game systems_ table at the bottom of this guide. These emulators are commonly shipped as a ZIP file that can be unpacked anywhere on the filesystem.
In order for ES-DE to find these emulators you need to add their directories to the operating system's Path environment variable. This is very easy to do, just open the _Settings_ application and then search for _path_ in the _Find a setting_ search box. Select the _Edit the system environment variables_ entry and then click the _Environment variables..._ button and add the emulator directory to the _Path_ variable. You need to restart ES-DE after changing the variable, but following this the emulator should be found when launching a game. If running ES-DE via Steam, you need to restart Steam as well to apply the changes to the Path variable.
The second alternative is to use the portable/ZIP release of ES-DE. This can be unzipped anywhere, including to removable devices such as hard drives or USB memory sticks. Together with games and emulators this makes for a fully portable retrogaming solution. There is a README.txt file distributed with this release that describes the setup, but essentially you just place your games in the ROMs directory and your emulators in the Emulators directory, both of which are included in the portable release.
If you want to create your own portable intallation from scratch or customize the setup, [INSTALL.md](INSTALL.md#portable-installation-on-windows) provides additional details.
As macOS does not support Vulkan some emulators are not available, and some that do exist have not been updated for this operating system in recent years. As well many emulators available for download are not codesigned and notarized which requires you to override the operating system's security settings to be able to use them. If you see an error popup stating the application couldn't be checked for malicious software or that the developer couldn't be verified, go to _System Preferences_, then _Security & Privacy_ and click the _Open Anyway_ button under the _General_ tab. Just note that doing so comes with some potential risks of virus infections and similar. Additionally some emulators are available via the Homebrew package manager, and these do not have the security issues just mentioned so they should be fine to use. Most RetroArch cores are also available on macOS so overall this operating system is still fine for retrogaming albeit with some restrictions.
Lack of controller support is a problem though, and in some instances controller drivers are available but quite buggy. In general it seems as if Sony PlayStation controllers are better supported than Microsoft Xbox controllers. For third party controllers you need to investgate the macOS support as it seems to differ quite a lot.
ES-DE is available both as an Intel/x86 build and as a native M1 build. If running on an M1 Mac it's possible to launch either M1 or Intel emulators from ES-DE and in some instances it's recommended to go for the Intel versions. The reason is that some emulators are not yet working properly on the M1 architecture, and for RetroArch some cores are only available for the x86 platform. So investigate what makes most sense for your setup. Over time this situation should improve as M1 support matures.
A macOS-specific requirement is that the RetroArch setting "Start in Fullscreen mode" is set as enabled or ES-DE will not be able to switch to the emulator window when launching games. As a workaround you can switch to the window manually using Command + Tab but it probably doesn't make sense to run emulators in windowed mode anyway. It's unclear if only RetroArch is affected by this issue, at least it has not been observed for any other emulators so far. The standalone PlayStation 2 emulator PCSX2 has a similar issue but that seems to be GPU driver related and is problematic also on other operating systems. If using this emulator you need to manually switch to the PCSX2 window using Command + Tab after launching a game.
The first time you launch a RetroArch-emulated game from within ES-DE the operating system will present you with a security option with the following description:
`"EmulationStation Desktop Edition" would like to access files in your Documents folder.`
If you don't allow this, you will not be able to place system BIOS ROMs in the RetroArch default system directory `~/Documents/RetroArch/system` even if you've already given RetroArch access to this folder. This is so because RetroArch runs as a subprocess to ES-DE and therefore inherits the security settings from the parent application. Attempting to launch a game without enabling the access will simply display an error message in the emulator that the BIOS files are missing. This of course only applies to emulators that require BIOS ROMs, all other games should work fine regardless of this security setting.
If you accidentally refused ES-DE the folder access, you can fix this by opening _System Preferences_, selecting _Security & Privacy_ and within the GUI choose _Files and Folders_. The option you need to enable is _Documents Folder_ under _EmulationStation Desktop Edition_.
A minor annoyance is that macOS creates metadata files starting with ._ in the filename when placing game/ROM files on some filesystem types such as exFAT. This means that you will see double entries inside ES-DE for all such games. To hide these extra files, the option _Show hidden files and folders (requires restart)_ in the _Other settings_ menu can be set to disabled.
Another problem on macOS 11 Big Sur (and possibly older OS versions) is that when connecting a Sony DualShock 4 controller either via Bluetooth or using a USB cable, two separate controller devices are registered in parallel. This is a bug in either macOS or the DualShock driver and it makes it seem as if ES-DE is registering double button presses when actually two separate controller devices are generating identical input. A workaround if using Bluetooth mode is to plug in the USB cable just after connecting the controller, wait a second or two and then remove the cable again. This will remove the cabled device, leaving only the Bluetooth device active. Another workaround is to enable the setting _Only accept input from first controller_ in the ES-DE input device settings. The reason why this bug may not be visible in some other games and applications is that ES-DE enables and auto-configures all connected controllers. The issue appears to be resolved in macOS Monterey.
As the Steam Deck is essentially a Linux desktop computer with a custom user interface, there is really not much specifically to consider when running ES-DE compared to any other Linux-based operating system. There is a specific AppImage available for the Steam Deck though that is recommended to use, as a number of settings will be tuned for the best possible experience on this device.
For Flatpak releases of some emulators you may need to give extra permissions to be able to launch games placed on external devices such as a memory card. This is the case for instance for melonDS and RPCS3. The easiest way to do this is by using [Flatseal](https://flathub.org/apps/details/com.github.tchx84.Flatseal). The option you need to enable is _All system files_ in the _Filesystem_ section.
ES-DE on the Raspberry Pi requires a desktop environment, or more specifically a window manager and a sound server (like PulseAudio or PipeWire). There are no plans to add support for direct hardware access to the framebuffer or to ALSA. If you want to use your Raspberry Pi as an appliance, take a look at [RetroPie](https://retropie.org.uk), [Recalbox](https://www.recalbox.com) or [Batocera](https://batocera.org) instead.
The Raspberry Pi 4/400 is the minimum recommended version and earlier boards have not been tested. The GPU memory should be set to at least 256 MiB using `raspi-config` and the GL driver must be set to `GL (Fake KMS)` or the performance will be horrible. On Raspberry Pi OS 11 the KMS option is enabled by default.
In general, 720p works fine with the RPi 4, and 1080p is tolerable but not really a nice and smooth experience. Due to the relative weakness of the Rasperry Pi GPU, the video scanline rendering options for the screensaver and media viewer have been disabled (they're enabled by default on all other platforms). These options can be re-enabled via the menu if you don't mind lower video framerates.
Both the 32-bit (armv7l) and 64-bit (aarch64) versions of Raspberry Pi OS are supported. Although the 64-bit version of ES-DE actually runs much better than the 32-bit version it's still generally recommended to go for the 32-bit OS for now. The reason is that the Raspberry Pi Foundation has still not officially released the 64-bit version of Raspberry Pi OS so it's somewhat of a beta with some functionality apparently broken. As well there seems to be issues with installing RetroArch cores on aarch64 so you would probably need to compile them from source code.
At the time of writing the Snap version of RetroArch appears broken and won't start on the 32-bit OS, so the Flatpak version would have to be installed. That is accomplished using these commands:
Following this you need to reboot, and then run this command:
```
sudo flatpak install retroarch
```
This will download and install a few hundred megabytes of data as there are some dependencies. Unfortunately the Flatpak environment does not seem to be properly setup so you will have to launch RetroArch like this to install your emulator cores:
On Raspberry Pi OS 10 Sony DualShock 4 controllers have problems with some button presses that don't register correctly. The issue appears resolved on Raspberry Pi OS 11.
On Raspberry Pi OS 11 there are various graphics issues and sometimes the application or emulator completely freezes which requires a power cycle of the machine. This is seemingly due to GPU driver bugs and we can only wait for OS updates to address these problems. These issues have not been encountered on Raspberry Pi OS 10 so for now this older OS version is recommended.
The game systems configuration file `es_systems.xml` is located in the ES-DE resources directory which is part of the application installation. As such this file is not intended to be modified directly. If system customizations are required, a separate es_systems.xml file should instead be placed in the `custom_systems` folder in the ES-DE home directory.
On Unix this means /home/\<username\>/.emulationstation/custom_systems/es_systems.xml, on macOS /Users/\<username\>/.emulationstation/custom_systems/es_systems.xml and on Windows C:\Users\\<username\>\\.emulationstation\custom_systems\es_systems.xml
Although it's possible to make a copy of the bundled configuration file, to modify it and then place it in this directory, that is not how the system customization is designed to be done. Instead the intention is that the file in `custom_systems` complements the bundled configuration, meaning only systems that are to be customized should be included.
For example you may want to replace the emulator launch command, modify the full name or change the supported file extensions for a single system. In this case it wouldn't make sense to copy the complete bundled file and just apply these minor modifications, instead an es_systems.xml file only containing the configuration for that single system should be placed in the custom_systems directory.
The instructions for how to customize the es_systems.xml file can be found in [INSTALL.md](INSTALL.md#es_systemsxml). There you can also find some examples of custom files that you can copy into ~/.emulationstation/custom_systems/ and modify as required.
ES-DE is designed to be backward compatible to a certain degree. That is, it should be able to read data from other/previous EmulationStation versions such as the RetroPie fork. But the opposite is not true and it's a one-way ticket for your gamelist.xml files and your custom collection files when migrating to ES-DE as they will be modified in ways that previous ES versions will see as data loss. For instance ES-DE does not use image tags inside the gamelist.xml files to find game media but instead matches the media to the names of the game/ROM files. So it will not save any such tags back to the gamelist files during updates, effectively disabling the game media if the files are opened in another ES fork.
It's also strongly adviced to not rename an old es_settings.cfg file to es_settings.xml for use in ES-DE. Although this has been tested to some extent, it may cause undefined behavior.
If migrating from Batocera or Recalbox, be aware that ES-DE follows the RetroPie naming conventions for game systems. This means that your game files may not be found unless the folders are renamed accordingly. Such an example is the Sega SG-1000 system which in Batocera and Recalbox has the _sg1000_ system name, but is _sg-1000_ in RetroPie and ES-DE. See the [Supported game systems](USERGUIDE.md#supported-game-systems) table at the bottom of this guide for the correct system names in ES-DE. This issue also means that theme sets that were written or adapted specifically for Batocera or Recalbox may display unthemed systems in ES-DE. All RetroPie theme sets should however work fine (of course assuming that all your systems are actually supported by the theme set).
ES-DE fully supports high resolution displays such as 1440p, 4K, 6K, 8K, ultrawide monitors etc. But many emulators (e.g. RetroArch) will also run using the same resolution which may cause performance problems on slower machines or when using resource intensive shaders. Although some emulator cores will have options to set their internal resolution, they still need to be scaled up to the screen resolution.
A solution to this is to use the custom event scripts functionality to set a temporary resolution upon launching a game that will be reverted when returning to ES-DE. Such a setup is detailed in [INSTALL.md](INSTALL.md#custom-event-scripts) for Unix, but should hopefully be possible to implement similarly on Windows. When going for this setup it's important that the setting _Run in background (while game is launched)_ is disabled or ES-DE may not be able to correctly switch to the emulator window when launching games.
On macOS it's problematic to change screen resolutions on the fly or on a per-application basis as Apple has seemingly disabled most of this functionality in recent operating system releases. The only real option here is to lower the display resolution prior to launching ES-DE.
ES-DE automatically configures the keyboard and any connected controllers using default button mappings, and normally no additional setup is required. But if you would like to apply custom button mappings for your devices or if you have an unusual device which isn't automatically configured, you can run the _Configure keyboard and controllers_ tool from the _Input device settings_ entry on the main menu.
The actual procedure to map the inputs should be self-explanatory, just follow the on-screen instructions. Note that custom button mappings will not change the help prompts.
Any custom configuration is applied per unique device ID (GUID). So if two identical controllers are used with ES-DE, both will have the same configuration applied. If connecting controllers of the same type but of different revisions, the GUID may differ and therefore the custom configuration would need to be applied to each device individually.
If you have issues with your input configuration, as a last resort you can reset all the mappings by deleting or renaming the file ~/.emulationstation/es_input.xml.
When starting ES-DE with the default settings, you will see the System view first. From here you can navigate your game systems and enter their respective gamelists.
Depending on the theme, the system navigation carousel can be horizontal, vertical or displayed as a wheel. The default theme rbsimple-DE provides horizontal navigation, i.e. you browse your systems by scrolling left or right.
The game systems are sorted by their full names by default, as defined in the es_systems.xml file. It's however possible to set a custom sortname per system, as explained in the [INSTALL.md](INSTALL.md#es_systemsxml) document.
Upon startup with the default settings, ES-DE is set to the gamelist view style **Automatic**. In this mode the application will look for any game media files (videos and images) and set the view style accordingly. If at least one image is found for any game, the view style **Detailed** will be shown, and if at least one video file is found, the view style **Video** will be selected (superceding the Detailed style). If no game media files are found for a system, the simple **Basic** view style will be selected. This automatic selection is applied per game system.
Note that the Video view style requires that the theme supports it. If not, the Detailed style will be selected instead. The default theme rbsimple-DE supports both of these view styles.
It's possible to manually set a specific gamelist view style in the UI settings entry of the main menu, but this is applied globally regardless of what media files are available per game system. The manual setting also overrides the theme-supported view styles which has the potential of making ES-DE very ugly indeed if the theme does not support the selected view style.
In addition to the styles just described, there is a **Grid** view style as well, but as of ES-DE version 1.2 this does not work correctly and is set as deprecated. Future ES-DE releases will remove this style entirely.
If the theme supports it, there's a gamelist information field displayed in the gamelist view, showing the number of games for the system (total and favorites) as well as a folder icon if a folder has been entered. When applying any filters to the gamelist, the game counter is replaced with the amount of games filtered, as in 'filtered / total games', e.g. '19 / 77'. If there are game entries in the filter result that are marked not to be counted as games, the number of such files will be indicated as 'filtered + filtered non-games / total games', for example '23 + 4 / 77' indicating 23 normal games, 4 non-games out of a total of 77. Due to this approach it's theoretically possible that the combined filtered game amount exceeds the number of counted games in the collection, for instance '69 + 11 / 77'. This is not considered a bug and is so by design. This gamelist information field functionality is specific to ES-DE so older themes will not support this.
Another feature which requires theme support is **Badges**, which is a set of icons displaying the status for various metadata fields. The currently supported badge types are _favorite, completed, kidgame, broken, controller_ and _alternative emulator_. If any of the first four metadata fields have been set for a game, their corresponding badges will be displayed. If a game-specific controller has been selected via the metadata editor, the corresponding controller badge will be shown, and if an alternative emulator has been selected for the specific game, that badge will be displayed. Setting an alternative emulator system-wide will not display this badge as it's only intended to indicate game-specific overrides. As well, disabling the option _Enable alternative emulators per game_ will also hide the alternative emulator badges.
_Here's an example of what the Basic view style looks like. Needless to say, ES-DE is not intended to be used like this. After scraping some game media for the system, the view style will automatically change to Detailed or Video (assuming the Automatic view style option has been selected)._
* Kiosk - The main menu will be severely restricted, only displaying the entry to change the audio volume. The game options menu will be restricted as well, removing the metadata editor and the ability to modify custom game collections. And finally the ability to flag or unflag games as favorites will be removed. Apart from this all games will be playable.
* Kid - Only games marked as being suitable for children will be displayed (this flag is set manually per game using the metadata editor). Additionally, the game options menu is disabled, as well as the screensaver controls and the ability to flag and unflag games as favorites. There is also a separate option available to enable or disable the main menu when in Kid mode, see _Enable menu in kid mode_ for additional information.
There is an unlock code available to revert to the Full mode from the Kiosk or Kid mode, as is described when changing this setting from the main menu. By default the button sequence is **Up, Up, Down, Down, Left, Right, Left, Right, B, A** (or equivalent buttons if an Xbox controller is not used). Either the keyboard or a controller can be used to input the passkey sequence, but it can't be entered when a menu is open.
The application can also be forced into any of the three modes via the command line options `--force-full`, `--force-kiosk` and `--force-kid`. This is only temporary until the restart of the application, unless the settings menu is entered and the setting is saved to the configuration file (this assumes that the main menu is available in the selected UI mode of course).
There is a help system available throughout the application that provides an overview of the possible actions and buttons that can be used. But some general actions are never shown, such as the ability to quick jump in gamelists, menus and text input fields using the shoulder and trigger buttons. It's also possible to disable the help system using a menu option for a somewhat cleaner look.
The built-in help system will provide a contextual summary of the available navigation options, but here's still a general overview. These are the buttons mappings automatically applied by ES-DE, but they can be customized using the input configurator as described earlier in this document. It's not an exhaustive list, but it covers most situations. The button names are based on the Xbox 360 controller as that is the naming convention used by the SDL library which handles the controller input in ES-DE.
Navigate between gamelists (if the _Quick system select_ option has been enabled), between systems in the system view (if the theme has a horizontal carousel) and between media files in the media viewer. If the _Enable screensaver controls_ option has been enabled, either button also randomly selects a new game when using the Video or Slideshow screensavers.
Opens and closes the game options menu in the gamelist view, or toggles the screensaver in the system view (if the _Enable screensaver controls_ setting is enabled).
Jumps to a random game or system depending on whether pressed when in the system view or gamelist view. Only available if the _Enable random system or game button_ option has been enabled.
Starts the game media viewer (which is accessible from the gamelist views). Used by some other minor functions as explained by the help system and/or this guide.
Marks games as favorites in the gamelist view (if the _Enable toggle favorites button_ option has been enabled). Used by some other minor functions as explained by the help system and/or this guide.
ES-DE is a game browsing frontend and does not provide any emulation by itself. It does however come preconfigured for use with emulators as setup in the `es_systems.xml` file. By default it's primarily setup for use with [RetroArch](https://www.retroarch.com) but this can be modified if needed. If you're interested in customizing your es_systems.xml file, please refer to the [INSTALL.md](INSTALL.md#es_systemsxml) document which goes into detail on the structure of this file and more advanced configuration topics in general.
Installation and configuration of RetroArch and other emulators is beyond the scope of this guide, but many good resources can be found online on how to do this.
Keep in mind that ES-DE will not install any RetroArch cores, you need to do this manually from within the RetroArch user interface.
A general recommendation regarding installation on Linux is to try to avoid the RetroArch releases included in the OS repositories as they're usually quite limited with regards to the number of available cores, and they're usually older versions. Instead go for either the Snap, Flatpak or AppImage distributions or build from source.
If using the Snap distribution you need to run the following command if you intend to place your ROMs on a removable device such as a USB-connected hard drive:
The default es_systems.xml file is paired with a file named es_find_rules.xml which tries to find the emulators and cores using some predefined rules. For Windows this should normally just work, and for macOS too as long as RetroArch is installed at the default location /Applications/RetroArch.app. For Unix/Linux there is one exception that is problematic which is AppImage packages as there is no standardized directory for storing these files. Read more [here](USERGUIDE.md#using-emulators-in-appimage-format-on-linux) on how to get the AppImage release of RetroArch to work.
If ES-DE is unable to find an emulator when a game is launched, a notification popup will be shown. Likewise a notification will be shown if the defined emulator core is not installed. The es_log.txt file will also provide additional details.
## Using the Steam release of RetroArch
On Windows it's no problem to use the Steam release of RetroArch although you may have to add the installation location manually to your Path environment variable. By default the following locations will be searched:
If you have installed RetroArch at another location, simply start the Settings application, search for _path_ in the _Find a setting_ field and choose _Edit environment variables for your account_. Edit the _Path_ variable and add the directory where RetroArch is installed. This is required as there is no apparent way for ES-DE to find where RetroArch has been installed by the Steam application.
Unfortunately on Linux it's at the moment not possible to run the Steam release of RetroArch due to technical reasons. This RetroArch release runs as a type of container which can't be executed from ES-DE while correctly passing the necessary core and game options. Similarly it's not possible to launch RetroArch via the Steam application either as there seems to be a bug in Steam or RetroArch that prevents blankspaces from being present in game ROM files when passed as arguments (this works fine on Windows so it's definitely a Linux-specific issue and as well the same problem occurs if attempting to manually enter the launch command from a terminal window).
AppImages are a great way to package emulators on Linux as they work across many different distributions, and launching and running them introduces virtually no overhead. There is one problem though in that there is no standardized directory for storing these files, meaning ES-DE could have issues locating them.
As such all bundled emulator configuration entries that support AppImages will look for these files in the following directories:
```
~/Applications/
~/.local/bin/
~/bin/
```
But even if the directory is known, another issue is that many AppImages contain version information in the filename, such as:
```
rpcs3-v0.0.19-13103-cc21d1b3_linux64.AppImage
```
ES-DE needs to have a specific filename to be able to find the emulator, so the easiest solution is to create a symlink to the AppImage file, such as the following:
This approach also works when using [AppImageLauncher](https://github.com/TheAssassin/AppImageLauncher) which is recommended as it properly integrates AppImages into the application menu and such. When first launching an AppImage with AppImageLauncher installed a question will be asked whether to integrate the application. If accepting this, the AppImage will be moved to the `~/Applications` directory and a hash will be added to the filename, like in this example:
As the hashed filename created by AppImageLauncher will be retained also after upgrading AppImages to newer versions, ES-DE will still be able to find the emulator.
At the moment the following emulators are supported in AppImage format:
Symlinking RetroArch is only required if using AppImageLauncher as the filename is otherwise not containing any version information, instead simply being named `RetroArch-Linux-x86_64.AppImage`. The same is true for DuckStation.
Note that the names are case sensitive, so for instance _rpcs3.appimage_ will not be found by ES-DE.
Also make sure to set the AppImage as executable or ES-DE will not be able to launch it. You do this on the actual file, not on the symlink. For example:
Normally on Linux you would install emulators using either one of the established package formats, i.e. Flatpak, AppImage or Snap, or you would install them using the operating system repository. Less likely would be to build from source code and install to a standard system directory. In all these instances ES-DE should be able to find the emulator when launching a game. But in some rare cases you may instead manually download an emulator as an archive file to unzip somewhere on the file system. Normally you would want to place these files in your home directory, and if running a distribution that has an immutable filesystem (such as SteamOS), you don't even have the choice to install them to a standard system directory.
For these situations ES-DE looks for emulators in the same directories where it looks for AppImages (as explained in the section above), meaning:
```
~/Applications/
~/.local/bin/
~/bin/
```
So placing a manually downloaded emulator binary in either of these directories will make ES-DE able to locate it during game launch.
The following manually downloaded emulators are supported when using the bundled configuration:
| System name | Emulator | Filename configuration |
In general ES-DE does not pass command line parameters to emulators to start them in fullscreen mode. This is so as for most (if not all) emulators, command line arguments overrides the settings the user has defined. This means that windowed mode would have become impossible to achieve without creating custom systems configuration entries if ES-DE enforced fullscreen mode. There are only a very few exceptions for emulators where there is no other way to enter fullscreen mode than by passing such options during game launch.
So if an emulator starts in windowed mode and you prefer to have it running in fullscreen mode instead, make sure to enable that option in the emulator settings or configuration file (which should be a one-time job).
For most systems this is straightforward, just put your game files into the folder corresponding to the platform name (these names can be found at the [end](USERGUIDE.md#supported-game-systems) of this guide.)
Let's start with the simple scenario of a single ROM file per game, which is the case for the majority of platforms. In this example we're setting up ES-DE to play Nintendo Entertainment System games.
The supported file extensions are listed in [unix/es_systems.xml](resources/systems/unix/es_systems.xml), [macos/es_systems.xml](resources/systems/macos/es_systems.xml) and [windows/es_systems.xml](resources/systems/windows/es_systems.xml) but if you generated the game system directories on first application startup, there will be a file named systeminfo.txt in each game system directory that includes the list of supported file extensions.
It's highly recommended to use filenames that are corresponding to the full name of the game, otherwise you will need to manually feed the scraper the game name when scraping which is very tedious.
**Note:** Symlinks are supported for both ROM directories and individual game files, but make sure to not symlink between files within the same system directory or there may be undefined application behavior when scraping, launching games etc.
The default game folder is ~/ROMs. On Unix this defaults to /home/\<username\>/ROMs, on macOS /Users/\<username\>/ROMs and on Windows C:\Users\\<username\>\ROMs\. Ifthe--homecommandlineoptionwasusedtostartES-DE,thetildesymbolwillresolvetowhateverdirectorywaspassedasanargumenttothisoption.
Assuming the default ROM directory is used, we need to create a subdirectory corresponding to the \<path\> tag in es_systems.xml, for this example it's `nes`.
That's it, start ES-DE and the NES game system should be populated. You can now scrape information and media for the games, and assuming you've setup RetroArch correctly with the Nestopia UE core, you can launch the games. If you instead prefer to use any of the three alternative emulators listed above (FCEUmm, Mesen or QuickNES) you can install one of these cores instead and change your emulator preference using the _Alternative emulators_ interface in the _Other settings_ menu. Note that alternative emulators are only available for some game systems.
For some systems, there are sometimes (or always) multiple files per game. Such an example would be the Commodore 64 when multidisk games are being played. For such instances, simply group the files inside folders.
It's highly recommended to create `.m3u` playlist files for multi-disc images as this normally automates disk swapping in the emulator. It's then this .m3u file that should be selected for launching the game.
Setting the directories to the same name as the .m3u files will interpret them as files, meaning they will behave just like any normal files inside ES-DE instead of being displayed as folders. When launching such a game, the file inside the directory that matches the directory name will be passed to the emulator. See the following section below for more information about this functionality.
This setup is of course entirely optional, you can also leave the directories as normal folders, meaning they will behave just like you would expect, i.e. you will have to enter them and then select the file you want to launch. If going for this setup it's possible to easily hide the files that are not relevant using the metadata editor.
There are two scenarios where it's useful to interpret directories as files inside ES-DE. The first one is to hide the directory structure for multi-disc games and similar while still being able to directly launch files inside these folders, and the second is that some emulators support passing a directory rather than an individual file as the game ROM argument.
In both cases, renaming a directory to one of the supported file extensions will automatically make ES-DE interpret it as a file. This means that the directory can be part of the automatic collections and any custom collections.
The only difference between a real file and a directory interpreted as a file is that the _Delete_ button in the metadata editor will be disabled as ES-DE does not support deletion of directories for safety reasons.
For the first scenario, to automatically launch a file inside a directory, just rename the directory to the same name as the file inside the folder that you would like to launch. For example:
In this case the directory is named _Jet Grind Radio.cue_, i.e. exactly the same name as one of the files inside the directory. This means that when launching the game, `~/ROMs/dreamcast/Jet Grind Radio.cue/Jet Grind Radio.cue` will actually be passed to the emulator.
~/ROMs/psx/Final Fantasy VII.m3u/Final Fantasy VII (Disc 1).chd
~/ROMs/psx/Final Fantasy VII.m3u/Final Fantasy VII (Disc 2).chd
~/ROMs/psx/Final Fantasy VII.m3u/Final Fantasy VII (Disc 3).chd
~/ROMs/psx/Final Fantasy VII.m3u/Final Fantasy VII.m3u
```
In exactly the same manner, the file `~/ROMs/psx/Final Fantasy VII.m3u/Final Fantasy VII.m3u` will be passed to the emulator on game launch. See the section just above this one, _Multiple game files installation_ for details on how .m3u files work.
The second scenario is when an emulator supports passing a directory rather than a file to launch a game. Such an example is the PlayStation 3 emulator RPCS3.
For PS3 games the extension in es_systems.xml is .ps3 so this is what a game directory could look like:
Also in this case the directory will be displayed as a regular game file inside ES-DE and when launching the game the directory is passed as the game ROM argument to RPCS3.
Not all systems are as simple as described above, or there may be multiple ways to do the configuration. Specifics for such systems will be covered here. Consider this a work in progress as there are many platforms supported by ES-DE.
For all the supported MAME variants as well as Final Burn Alpha/FinalBurn Neo and Neo Geo, single file archives should be used. But these should retain the MAME names as filenames since ES-DE ships with MAME lookup tables, meaning the MAME names are expanded to the full game names.
This is required by the TheGamesDB scraper where the expanded filenames are used for game searches. (Screenscraper natively supports searches using the MAME names). It's also quite nice to have the gamelist populated with the expanded game names even before any scraping has taken place.
The Nintendo Switch emulator Yuzu is distributed as a Snap package, Flatpak package or AppImage on Linux and as a regular installer on Windows. At the moment there is unfortunately no macOS release of this emulator and it's unclear if it can run on BSD Unix.
But if using the AppImage release it's a bit more complicated. See [here](USERGUIDE.md#using-emulators-in-appimage-format-on-linux) for more information on how to get it to work.
For Windows, ES-DE will look for _yuzu.exe_ in the system Path as well as in the default installation directory `~\AppData\Local\yuzu\yuzu-windows-msvc\`
Apart from the potential difficulty in locating the emulator binary, there are some special configuration steps required for the emulator, refer to the Yuzu website for more information about this.
This section is specific to Windows as Cemu is currently only supported on this operating system.
Cemu works a bit different compared to most other emulators, with games stored in an unpacked format. The content of each game is divided into the three directories _code, content_ and _meta_.
The first step is to prepare the target directory in the `wiiu` ROMs directory, for this example we'll go for the game _Super Mario 3D World_. So simply create a directory with this name inside the wiiu folder. It should look something like the following:
```
C:\Users\myusername\ROMs\wiiu\Super Mario 3D World\
```
The next step is done inside the emulator user interface. You should install the game, any updates as well as optional DLCs to the Cemu NAND. After the installation is completed, right click on the game and choose _Game directory_. An Explorer window should now open showing the content of the game. Here's the game directory for our example:
Go up one level and copy the _code, content_ and _meta_ directories and paste them into the C:\Users\myusername\ROMs\wiiu\Super Mario 3D World\ directory. It should now look something like the following:
```
C:\Users\myusername\ROMs\wiiu\Super Mario 3D World\code
C:\Users\myusername\ROMs\wiiu\Super Mario 3D World\content
C:\Users\myusername\ROMs\wiiu\Super Mario 3D World\meta
```
Starting ES-DE should now show the _Super Mario 3D World_ entry for the Wii U system. The actual game file with the extension .rpx is stored inside the _code_ directory, and does not normally match the name of the game. For this example it's named `RedCarpet.rpx`. When scraping the .rpx file you therefore need to refine the search and manually enter the game name. ES-DE fully supports scraping of directories, so you can scrape the _Super Mario 3D World_ folder as well.
On Windows RPCS3 does not ship with an installer but rather as a zip file that contains all application files. You will need to unzip the content and manually add that directory to your environment Path variable so that ES-DE will be able to find the emulator binary rpcs3.exe, or you can optionally place the RPCS3 directory inside the ES-DE installation directory in which case it will be found when launching a game. Both these options are described in more detail [here](USERGUIDE.md#specific-notes-for-windows)
On Linux RPCS3 is shipped as a Snap package, Flatpak package or AppImage. If installed as a Snap or Flatpak or if built from source code, ES-DE should be able to easily locate the emulator binary.
But if using the AppImage release it's a bit more complicated. See [here](USERGUIDE.md#using-emulators-in-appimage-format-on-linux) for more information on how to get it to work.
If using the Flatpak release and your games are stored on an external device (such as a memory card if using a Steam Deck), you need to give RPCS3 the necessary permissions. The easiest way to do this is by using [Flatseal](https://flathub.org/apps/details/com.github.tchx84.Flatseal). The option you need to enable is _All system files_ in the _Filesystem_ section.
As for the game installation on both Windows and Linux as well as on macOS, you need to retain the directory structure of the Blu-ray disc or the directory created by installing the .pkg file. Each directory needs to be renamed by adding the .ps3 extension, which will make ES-DE interpret the directory as if it were a file and pass that directory to the emulator when launching a game.
If you've installed a .pkg using RPCS3 you can either symlink to the installation directory or move the directory to the ROMs folder. Also in this case the directory (or symlink) needs to be named with the .ps3 extension.
There are multiple ways to run Amiga games, but the recommended approach is to use WHDLoad. The best way is to use hard disk images in `.hdf` or `.hdz` format, meaning there will be a single file per game. This makes it just as easy to play Amiga games as any console with game ROMs.
An alternative would be to use `.adf` images as not all games may be available with WHDLoad support. For this, you can either put single-disc images in the root folder or in a dedicated adf directory, or multiple-disk games in separate folders. It's highly recommended to create `.m3u` playlist files for multi-disc images as described earlier.
Advanced topics such as the need for the Amiga Kickstart ROMs to run Amiga games is beyond the scope of this guide, but the following page is recommended for reading more about how this setup can be achieved:
The DOS (and PC) platform uses the DOSBox emulator and the recommended approach here is to keep the directory structure intact, just as if running the game on a real DOS PC. So this means one folder per game in ES-DE. It's also recommended to set the metadata field _Count as game_ to off for all files but the actual file used to launch the game, i.e. the binary or the .bat batch file. This is done so that the game counter correctly reflects the number of games you have installed. It's also possible to mark files and subdirectories as hidden to avoid seeing them in ES-DE. Both of these fields can be set using the metadata editor.
Apart from this, DOS games should work the same as any other system. The game folders can be scraped so that it looks nice when browsing the list of games, but make sure to also scrape the files used to launch the games or otherwise the entries in the collections _All games, Favorites_ and _Last played_ as well as any custom collections will miss the game metadata and game media. If you don't have these collections activated, then this can of course be skipped.
ScummVM overlaps a bit with DOS when it comes to the logic of setting it up. It's recommended to keep games in separate folders, so if you have a game distributed as a ZIP file, uncompress it to its own directory.
Although ScummVM supports launching of .exe files, ES-DE is currently not configured as such and it's instead recommended to create a .scummvm file in each game directory and launch that. This makes for a cleaner setup as you don't need to run game configuration utilities like INSTALL.EXE or SETUP.EXE directly as you would with DOSBox. Rather the game configuration is done within the ScummVM emulator.
The .scummvm files should simply contain a single word which is referred to as the _Game Short Name_. You can find the complete list of supported ScummVM games with their corresponding short names here:\
In order to avoid having to display each game as a directory inside ES-DE (that needs to be entered each time you want to launch a game), you can optionally interpret each game directory as a file. Make sure to read the _Directories interpreted as files_ section [here](USERGUIDE.md#directories-interpreted-as-files) to understand how this functionality works, but essentially the following would be the setup required for our example:
```
~/ROMs/scummvm/sky.scummvm/sky.scummvm
~/ROMs/scummvm/queen.scummvm/queen.scummvm
```
In this case the two entries _sky_ and _queen_ will show up inside ES-DE and these will be handled like any other game files and can be part of automatic and custom collections for instance.
The only drawback of this approach is that when scraping using TheGamesDB you will get very inaccurate results as this scraper service does not support ScummVM short names. It can however be worked around by refining the searches. ScreenScraper does natively support ScummVM short names and you should get very accurate results with this scraper service.
Ports are not really executed using emulators, but are rather applications running natively on the operating system. The easiest way to handle these is to add a simple shell script or batch file where you can customize the exact launch parameters for the game.
It's possible to add these files directly to the root folder, but normally it's recommended to setup a separate directory per game as there may be more than a single file required. For instance you often want to have easy access to the game setup utility which may have to be executed separately from the actual game.
These games are executed via the Lutris binary (well it's actually a Python script) and you simply create a shell script per game inside the lutris system directory.
Add the game information to each shell script using the syntax `lutris lutris:rungame/<game name>`
As an alternative, you can add the Lutris games to the Ports game system, if you prefer to not separate them. The instructions above are identical in this case except that the shell scripts should be located inside the `ports` directory rather than inside the `lutris` directory.
**Note:** Launching Steam games currently has some limitations such as missing error messages when a game fails to start as well as missing game output logging. ES-DE also needs to keep running in the background for technical reasons, which has some minor side effects.
On Windows it's straightforward to add Steam games to ES-DE, simply copy the Start Menu entries for your Steam games into the ~\ROMs\steam directory. These files have the .url extension and can be launched directly from within ES-DE.
For Linux and macOS it's a bit more complicated. For these platforms it's recommended to place shell scripts directly in the steam system directory, with filenames corresponding to the game names.
The game ID can be found by going to [https://store.steampowered.com](https://store.steampowered.com) and searching for a game. The Broforce example would have an URL such as this:
ES-DE supports the two scraper services [ScreenScraper.fr](https://www.screenscraper.fr) and [TheGamesDB.net](https://thegamesdb.net). In general TheGamesDB supports less formats and less systems, but in some areas such PC gaming, the quality is better and sometimes ScreenScraper is missing some specific information such as release dates where TheGamesDB may be able to fill in the gaps.
_Here's an example of the multi-scraper running in interactive mode, asking the user to make a selection from the multiple matching games returned by the scraper service._
The single-game scraper is launched from the metadata editor. You navigate to a game, open the game options menu, choose **Edit this game's metadata** and then select the **Scrape** button (alternatively the "Y" button shortcut can be used to start the scraper).
The multi-scraper is accessed from the main menu by entering the **Scraper** menu and then selecting the **Start** button (or the "Y" button shortcut can be used).
The default mode for the scraper is _Non-interactive_ mode, also referred to as _Automatic_ mode. When using this mode the selected systems are scraped without requiring any user input. This is quite convenient, but has the drawback of not asking for input if multiple matching games are returned by the scraper service. This could lead to the wrong game metadata and media being downloaded, but in practice this is quite rare so it's generally recommended to keep the automatic mode enabled. If no result is found for a game, the scraper will skip to the next one in queue.
If _interactive mode_ is instead enabled, the process of scraping games is basically identical between the single-game scraper and the multi-scraper. You're presented with the returned scraper results, and you're able to refine the search if the scraper could not find your game. Sometimes small changes like adding or removing a colon or a minus sign can yield better results. Note that searches are handled entirely by the scraper service, ES-DE just presents the results returned from the service.
When scraping in interactive mode it's recommended to keep the _Auto-accept single game matches_ option enabled as it will run the scraper in semi-automatic mode, only stopping to ask for user input if there are multiple results returned or if no game was found. If this option is disabled, the scraper will stop and ask for confirmation for every game.
By default, ES-DE will search using the metadata name of the game. If no name has previously been defined via scraping or via manually entering it using the metadata editor, the name used for searching will correspond to the physical filename minus all text inside either normal brackets `()` or square brackets `[]`. So for example the physical filename `Mygame (U) [v2].zip` will be stripped to simply `Mygame` when performing the scraper search.
By disabling the option _Search using metadata name_, the physical filename will be used even if there is a scraped or manually entered name for the game.
There is however an exception to this for arcade games (MAME and Neo Geo) when using the TheGamesDB scraper. As this service does not support searches using the short MAME names, these will be expanded to the full game names via a lookup in the MAME name database supplied with the ES-DE installation. But if using ScreenScraper the _Search using metadata name_ option is always respected as this service fully support scraping based on the short MAME names.
The miximages are generated by ES-DE. Normally that takes place automatically when scraping, but in this example of manually copying existing media files, the miximage offline generator should be used instead. This tool can generate the miximages for the complete game collection in one go. How that works is explained elsewhere in this guide.
Remember that on Unix filenames are case sensitive, and as well the file extensions must be in lower case, such as .png instead of .PNG or .Png or the file won't be found.
This menu can be accessed from both the system view and gamelist view. It contains the scraper, application settings and various tools such as the input configurator and the miximage generator. Settings are saved when navigating back from any menu screen, assuming at least one setting was changed. Pressing the application exit key (F4 by default) will also save any pending changes.
The password as registered on screenscraper.fr. This is masked using asterisks on the screen, and the password input field will be blank when attempting to update an existing password. This is by design and not a bug. Be aware that the es_settings.xml file contains the password in clear text.
Whether to use the account that has been configured. If this is disabled, the username and password setup on this screen will be ignored during scraping. This can be useful if you have scraping issues and want to check whether it's related to your account or if it's a general problem. Note that screenscraper.fr does not seem to return a proper error message regarding incorrect username and password, but starting ES-DE with the --debug flag will indicate in the log file whether the username was included in the server response.
Whether to scrape the names of the games. This does not affect the actual files on the filesystem and the game name is primarily used for appearance and sorting purposes. The downloaded media files are matched against the physical game files on the filesystem, and not against this metadata. See the comments under _Overwrite files and data_ below to understand some additional implications regarding game names.
**Controllers (arcade systems only)** _(ScreenScraper only)_
Scrapes controller metadata which is used to set the correct controller badge. This is only available for MAME arcade games, for systems such as _arcade_, _mame_, _neogeo_, _fba_ etc. This is so because ScreenScraper does not seem to provide controller information for other platforms. The type of controllers that are scraped are _joystick_ (separated into entries from no buttons up to 6 buttons), _steering wheel_, _flight stick_, _spinner_, _trackball_ and _lightgun_.
These are the settings for the miximage generator, which can either be run from the scraper (single-game scraper or multi-scraper) or from the offline generator. The miximage combines the screenshot, marquee, box/cover and physical media images to make a composite picture that is displayed in the gamelist view. There are various settings for the generator.
It's possible to select betweeen the 1280x960, 1920x1440 and 640x480 resolutions for the generated miximages. It's normally recommended to use the default option 1280x960 which gives good image quality without slowing down ES-DE too much. But for very weak machines, 640x480 may be a better option. The 1920x1440 resolution is normally not recommended as it brings little quality improvements over 1280x960 and slows down the gamelist browsing.
**Screenshot scaling method**
The _sharp_ scaling method uses nearest-neighbor interpolation which retains sharp pixels and looks better for most low-resolution retro games. The _smooth_ scaling method uses the Lanczos algorithm and produces smoother pixels. This may look better on some more modern games at higher resolutions. If unsure, use the _sharp_ method.
The size of the 3D game box, or the cover image if there is no 3D box and the _Use cover image if 3D box is missing_ setting has been enabled. The available options are _medium, small_ and _large_.
**Physical media size**
The size of the physical media image. The available options are _medium, small_ and _large_.
Some consoles such as Super Nintendo have game boxes with the cover printed horizontally rather than using the more common vertical format. If enabling this setting, those images will be rotated 90 degrees so they stand up like the box images for most other systems.
This is not a setting, but instead a GUI to generate miximages offline without going via the scraper. This tool uses the same game system selections as the scraper, so you need to select at least one system on the scraper menu before attempting to run it. All the miximage settings are applied in the same way as when generating images via the scraper. The prerequisite is that at least a screenshot exists for each game. If there is no screenshot, or if the screenshot is unreadable for some reason, the generation for that specific game will fail. There is statistics shown in the tool displaying the number of generated, overwritten, skipped and failed images. Any error message is shown on screen as well as being saved to the es_log.txt file. Note that although the system selections are the same as for the scraper, the _Scrape these games_ filter is ignored and the generator always attempts to generate miximages for all games in a system.
Multiple languages are supported by ScreenScraper, and this affects translations of game genres and game descriptions. As the option name implies this is the preferred language only as not all games have had their metadata translated. Unfortunately some less used languages have quite few games translated, but hopefully this will improve over time as there's an ongoing community effort to make more translations. If the preferred language is not available for a game, ES-DE will fall back to using the English metadata.
Affects both overwriting of metadata as well as actual game media files on the filesystem. Even with this option disabled, metadata entries which are set to their default values will be populated by the scraper. In other words, this option only affects overwriting of previously scraped data, or data manually entered via the metadata editor. Game names are considered as set to their default values if either corresponding to the physical game file on disk minus the extension (e.g. the entry _Commando_ if the file is named _Commando.zip_), or for arcade games if corresponding to the MAME names as defined in the bundled mamenames.xml. Note that this setting does not affect generated miximages, that is instead controlled by the setting _Overwrite miximages (scraper/offline generator)_ found in the miximage settings menu.
With this setting enabled, if any media files returned by the scraper seem to be invalid, the scraping is halted and an error message is presented where it's possible to retry or cancel the scraping of the specific game. In the case of multi-scraping it's also possible to skip the game and proceed to the next one in the queue. With this setting disabled, all media files will always be accepted and saved to disk. As of ES-DE v1.2 the file verification is quite basic and future versions will improve on this by using file checksums and other file integrity checks. There is an exception in place for box back covers when using ScreenScraper. As many of these specific images are broken, there is an automatic filter built in that is always active and which removes blank images and those containing only a few lines of pixels.
By default ES-DE will perform scraper searches based on the game name that has been manually set in the metadata editor, or that has been previously scraped. If you prefer to search using the physical filename regardless of such data being available, then disable this option. Note that when using TheGamesDB as scraper service for arcade games (MAME and Neo Geo), the short MAME name will always be expanded to the full game name as this scraper service does not support searches using short MAME names. In general it's recommended to disable this option if scraping arcade games using ScreenScraper as the MAME short names is much more reliable than using the metadata names.
It's possible to set a flag per game file or folder using the metadata editor to indicate that it should be excluded from the multi-scraper. This setting makes it possible to override that restriction and scrape all entries anyway.
If this setting is enabled and a folder has its flag set to be excluded from the scraper, then the entire folder contents are skipped when running the multi-scraper.
Enabling this option causes folders themselves to be included by the scraper. This is useful for DOS or ScummVM games or for multi-disc games where there is a folder for each individual game.
With this option enabled underscores _ in game names are converted to spaces when performing scraper searches. This affects both the single-game scraper and the multi-scraper and it will also be applied automatically to the _Refine search_ dialog.
ScreenScraper sometimes has issues with its TLS certificates which causes searches to randomly fail. It's normally resolved within a few days, but in the meanwhile activating this setting will have the scraper automatically make up to eight additional attempts when this error occurs. That is normally enough to complete the search, but if not, just press _Retry_ in the error dialog and ES-DE will try eight more times. This setting applies to both the single-game scraper and the multi-scraper. The following error notification dialog and corresponding es_log.txt entry is displayed when this error occurs: "Error downloading thumbnail: SSL peer certificate or SSH remote key was not OK".
Sets the view style to _Automatic, Basic, Detailed, Video_ or _Grid_. See the description [above](USERGUIDE.md#gamelist-view) in this document for more information regarding view styles.
Sets the user interface mode for the application to _Full, Kiosk_ or _Kid_. See the description [above](USERGUIDE.md#ui-modes) in this document for additional information.
The order in which to sort your gamelists. This can be overriden per game system using the game options menu, but that override will only be persistent during the application session. The _System_ sorting can not be selected here as it's only applicable to collection systems.
Animation to play when opening the main menu or the game options menu. Also sets the animation for the game launch screen. Can be set to _Scale-up_ or _None_.
This configures for how long to display the game launch screen when starting a game. The options are _Normal_, _Brief_, _Long_ and _Disabled_. If set to _Disabled_, a simple notification popup will be displayed instead.
**Blur background when menu is open** _(OpenGL renderer only)_
This option will blur the background behind the menu slightly. Normally this can be left enabled, but if you have a really slow GPU, disabling this option may make the application feel a bit more responsive.
With this option enabled, there are black pillarboxes (and to a lesser extent letterboxes) displayed around videos with non-standard aspect ratios. This will probably be most commonly used for vertical arcade shooters, or for game systems that has a screen in portrait orientation. For wider than normal videos, letterboxes are added, but this is quite rare compared to videos in portrait orientation. This option looks good with some theme sets such as rbsimple-DE, but on others it may be more visually pleasing to disable it. On less wide displays such as those in 4:3 aspect ratio this option should probably be disabled as it may otherwise add quite excessive letterboxing.
Whether to use a shader to render scanlines for videos in the gamelist view. The effect is usually pretty subtle as the video is normally renderered in a limited size in the GUI and the scanlines are sized relative to the video window size.
Whether to place all folders on top of the gamelists. If enabled the folders will not be part of the quick selector index, meaning they can no longer be quick-jumped to. That is, unless there are only folders in the gamelist in which case the folders will be handled like files.
With this setting enabled, there is a star symbol added at the beginning of the game name in the gamelist views. If you're not using a theme set which support badges, it's strongly recommended to keep this setting enabled. Especially so if the option to sort favorite games above non-favorites has been enabled. Otherwise favorite games would be sorted on top of the gamelist with no clear visual indication that they are favorites which would be quite confusing.
**Use plain ASCII for special gamelist characters**
There are some special characters in ES-DE such as the favorites star, the folder icon and the tickmark (seen when editing custom collections) that are displayed using symbols from the bundled Font Awesome. This normally looks perfectly fine, but on some specific theme sets with very pixelated fonts such as [es-themes-snes-mini](https://github.com/ruckage/es-theme-snes-mini) and [es-themes-workbench](https://github.com/ehettervik/es-theme-workbench) these symbols look terrible. For such themes, this option is available, which will use plain ASCII characters instead of the Font Awesome symbols. For the favorites an asterisk `*` will be used, for folders a hash sign `#` will be used and for the tickmark an exclamation mark `!` will be used. This only applies to the gamelist view, in all other places in the application the Font Awesome symbols are retained. Make sure to disable this option if not using such a pixelated theme as it looks equally terrible to enable this option on themes where it's not supposed to be used.
With this option enabled, there will be an overlay displayed when scrolling the gamelists quickly, i.e. when holding down the _Up_, _Down_, _Left shoulder_ or _Right shoulder_ buttons for some time. The overlay will darken the background slightly and display the first two characters of the game names. If the game is a favorite and the setting to sort favorites above non-favorites has been enabled, a star symbol will be shown instead.
**Enable virtual keyboard**
This enables a virtual (on-screen) keyboard that can be used at various places throughout the application to input text and numbers using a controller. The Shift and Alt keys can be toggled individually or combined to access many special characters. The general use of the virtual keyboard should hopefully be self-explanatory.
**Enable menu scroll indicators**
With this option enabled, "up and down" scroll indicators will be displayed in the upper right corner of menus (including the metadata editor and scraper) if there are more entries available than can be shown on the screen at the same time. These indicators will change dynamically as the list is scrolled. If the setting is disabled, a simplified static indicator will be displayed instead.
This setting enables the _Y_ button for quickly toggling a game as favorite. Although this may be convenient at times, it's also quite easy to accidentally remove a favorite tagging of a game when using the application more casually. As such it could sometimes make sense to disable this functionality. It's of course still possible to mark a game as favorite using the metadata editor when this setting is disabled. The option does not affect the use of the _Y_ button to add or remove games when editing custom collections.
This enables or disables the ability to jump to a random system or game. It's mapped to the thumbstick click button, either the left or right thumbstick will work. The help prompts will also visually indicate whether this option is enabled or not.
Some themes (including rbsimple-DE) display the game images briefly before playing the game videos. This setting forces the videos to be played immediately, regardless of the configuration in the theme. Note though that if there is a video available for a game, but no images, the video will always start to play immediately no matter the theme configuration or whether this settings has been enabled or not.
Settings for the media viewer that is accessible from the gamelist views.
**Keep videos running when viewing images**
With this option enabled, the video will continue to run when viewing the images for the game. If disabling this setting, the video will stop immediately when browsing to the first image, and it will restart when navigating back to the video.
**Stretch videos to screen resolution**
This will fill the entire screen surface but will probably break the aspect ratio of the video.
**Render scanlines for videos** _(OpenGL renderer only)_
Whether to use a shader to render scanlines for the videos. Be aware that this is quite demanding for the GPU.
**Render blur for videos** _(OpenGL renderer only)_
Whether to use a shader to render a slight horizontal blur which somewhat simulates a well-used CRT monitor. Be aware that this is quite demanding for the GPU.
After how many minutes to start the screensaver. If set to 0 minutes, the timer will be deactivated and the screensaver will never start automatically. It's however still possible to start the screensaver manually in this case, assuming the _Enable screensaver controls_ setting is enabled. While any menu is open, the screensaver will not start regardless of how this timer setting is configured.
This enables the ability to start the screensaver manually using the _Back_ button from the system view, but also while the screensaver is running to jump to a new random game using the _Left_ and _Right_ buttons, to launch the game currently shown using the _A_ button or to jump to the game in its gamelist using the _Y_ button. If this setting is disabled, any key or button press will stop the screensaver.
For how long to display images before changing to the next game. Allowed range is between 2 and 120 seconds in 2-second increments. The default value is 10 seconds.
This will display an overlay in the upper left corner, showing the game name and the game system name. A star symbol following the game name indicates that it's flagged as a favorite.
Using this option it's possible to use custom images instead of random images from the game library. As is the case with the rest of ES-DE, the supported file formats are JPG and PNG.
The directory for the custom images. The tilde `~` symbol can be used which will expand to the user home directory. It's also possible to use the %ESPATH% and %ROMPATH% variables which will set the directory relative to the ES-DE binary directory or the ROMs directory.
For how long to play videos before changing to the next game. Allowed range is between 0 and 120 seconds in 2-second increments. If set to 0 (which is the default value), the next game will be selected after the entire video has finished playing. If set to a higher value than the length of a game video, it will loop until reaching the swap time.
This will display an overlay in the upper left corner, showing the game name and the game system name. A star symbol following the game name indicates that it's flagged as a favorite.
Whether to use a shader to render a slight horizontal blur which somewhat simulates a well-used CRT monitor. Be aware that this is quite demanding for the GPU.
As the name implies, this sets the overall system volume and not the volume specifically for ES-DE. The volume change is applied when leaving the sound settings menu and not immediately when moving the slider.
Enables or disables navigation sounds throughout the application. Sounds are played when browsing systems and lists, starting games, adding and removing games as favorites etc. The sounds can be customized per theme, but if the theme does not support navigation sounds, ES-DE will fall back to its built-in samples.
Settings related to the input devices, i.e. the keyboard and controllers.
**Controller type**
This setting gives the ability to choose between the controller types _Xbox, Xbox 360, PlayStation 4, PlayStation 5_ and _SNES_ (Super Nintendo). Doing so alters the help icons and help text as well as the icons and text for the input device configurator. The setting is only cosmetic and does not change the controller behavior or the controller button mappings.
If enabling this option, only the first controller detected during startup will send its input to ES-DE (the keyboard input is unaffected by this setting and will be enabled regardless). This is a good way to limit potential chaos with multiple persons fighting over which games to start. Disconnecting and reconnecting controllers while ES-DE is running may change what is considered the first controller. This setting does not affect the emulators in any way, it's only applied to ES-DE.
This tool provides configuration of button mappings for the keyboard and controllers, as explained [here](USERGUIDE.md#input-device-configuration). Normally this is not required as ES-DE automatically configures all input devices, but button customizations may be useful in some special situations. You may also need to run this tool if you have an unusual controller which could not be automatically configured. Be aware that custom button mappings will not change the help icons or help text.
Handles collections, which are assembled using games present in the game systems. See the [collections](USERGUIDE.md#game-collections) section below in this document for more information.
If the theme set in use provides themes for custom collections, then this entry can be selected. For example, there could be themes for _Fighting games_ or _Driving games_ etc. The default rbsimple-DE theme set does not provide such themes for custom collections and in general it's not recommended to use this approach, as is explained [later](USERGUIDE.md#custom-collections) in this guide.
This permanently deletes a custom collection, including its configuration file on the file system. A list of available collections is shown, and a confirmation dialog is displayed before performing the actual deletion. Only one collection at a time can be deleted.
Whether to sort your favorite games above your other games. This is disabled by default, as for collections you probably want to be able to mix all games regardless of whether they are favorites or not.
With this option enabled, there is a star symbol added to each favorite game name. It works identically to the setting _Add star markings to favorite games_ under the _UI settings_ menu but is applied specifically to custom collections. It's disabled by default.
With this enabled, if you have created custom collections and there is no theme support for the names you've selected, the collections will be grouped in a general collection system which is correctly themed. It's strongly recommended to keep this option enabled as otherwise your collections would be completely unthemed which doesn't make much sense. This option is provided mostly for testing and theme development purposes.
Enables the system name to be shown in square brackets after the game name, for example _CONTRA [NES]_ or _DOOM [DOS]_. This is applied to both automatic and custom collections. It's recommended to keep this option enabled.
Using this interface it's possible to select alternative emulators to use per game system, which requires that these alternatives have been defined in the es_systems.xml file. Note that only systems that you have currently populated will be listed. To change to an alternative emulator, you simply select a system from the list and choose which alternative to use from the presented options. If you select an alternative emulator and later remove its corresponding entry from the es_systems.xml file, an error message will be shown on application startup telling you to review your invalid emulator selection. Games will still launch, but the default emulator will be used in this case. How to clear an invalid entry should be self-explanatory once you access the interface. It's also possible to set alternative emulators per game using the metadata editor. If this is done, it will take precedence and override the system-wide emulator selection for the specific game. The alternative emulator badges and the corresponding gamelist filter are controlled by these per-game alternative emulator values and not by the system-wide option.
The amount of video RAM to use for the application. Defaults to 256 MiB (184 MiB on the Raspberry Pi) which works fine most of the time when running at 1080p resolution and with a moderate amount of game systems. If running at 4K resolution or similar and with lots of game systems enabled, it's recommended to increase this number to 512 MiB or possibly more to avoid stuttering transition animations caused by unloading and loading of textures from the cache. Enabling the GPU statistics overlay gives some indications regarding the amount of texture memory currently used, which is helpful to determine a reasonable value for this option. The allowed range for the settings is 80 to 1024 MiB. If you try to set it lower or higher than this by passing such values as command line parameters or by editing the es_settings.xml file manually, ES-DE will log a warning and automatically adjust the value within the allowable range.
This option sets the display to use for ES-DE for multi-monitor setups. The possible values are the monitor index numbers 1, 2, 3 or 4. If a value is set here for a display that does not actually exist, then ES-DE will set it to 1 upon startup. Index 1 is the primary display for the computer. It's also possible to override the setting by passing the --display command line argument. Doing so will also overwrite the display index setting in es_settings.xml. The Display/monitor index option only changes the display used by ES-DE; the emulators need to be configured separately (which can easily be done globally if using RetroArch).
This gives the choice of which key combination to use to close the application. The default value is F4, but this can be changed to Alt + F4 on all operating systems. Additionally on macOS the Command + Q combination is selectable and on all other operating systems Alt + Q is selectable instead. Note that on Windows and most window managers on Unix/Linux, Alt + F4 will close the application regardless of the selected option as that key combination is a default which can't be restricted by ES-DE. Similarly on macOS, Command + Q always closes the application, so selecting this combination simply disables the previously selected exit button.
The metadata for a game is updated by scraping or by manual editing using the metadata editor, but also when launching it as this updates the _Times played_ counter and the _Last played_ timestamp. This setting enables you to define when to write such metadata changes to the gamelist.xml files. Setting the option to _Never_ will disable writing to these files altogether, except for some special conditions such as when a game is manually deleted using the metadata editor, when scraping using the multi-scraper (the multi-scraper will always save any updates immediately to the gamelist.xml files) or when changing the system-wide alternative emulator. In theory _On exit_ will give some small performance gains, but it's normally recommended to leave the setting at its default value which is _Always_. Note that with the settings set to _Never_, any updates such as the _Last played_ date will still be shown on screen, but during the next application startup, any values previously saved to the gamelist.xml files will be read in again. As well, when changing this setting to _Always_ from either of the two other options, any pending changes will be immediately written to the gamelist.xml files.
With this setting enabled, the taskbar will be hidden when launching ES-DE, and it will be restored when the application exits. This can make for a more seamless experience as the taskbar could otherwise flash by briefly when launching and returning from games.
Enabling this option makes ES-DE continue to run while a game is launched. This is normally not recommended as it leads to a slightly strange application behavior and it also removes the ability to capture return codes and log output from the emulators. Generally this option should only be enabled if there are issues with launching games while suspending ES-DE. Note however that some systems like Valve Steam will always keep ES-DE running in the background because they require it for technical reasons (i.e. those systems will override this menu option).
With this option enabled, videos with lower frame rates than 60 FPS, such as 24 and 30 will get upscaled to 60 FPS. This results in slightly smoother playback for some videos. There is a small performance hit from this option, so on weaker machines it may be necessary to keep it disabled for fluent video playback.
When this option is enabled, all gamelists will be loaded on application startup. This will increase the startup time slightly and lead to a higher initial memory utilization, but navigation will be smoother the first time a gamelist is entered. The improvement is especially noticeable when the _slide_ transition style has been selected.
If enabled, you will be able to select alternative emulators per game using the metadata editor, which will be used when launching the game. If disabled, the corresponding entry in the metadata editor will be hidden, the alternative emulator badges will not be displayed and it will not be possible to filter the gamelist based on these values. As well, the game will be launched using the default emulator, or using the system-wide alternative emulator if this has been configured for the game system. It's only recommended to disable this option for testing purposes.
If this option is disabled, hidden files and folders within the ROMs directory tree are excluded from ES-DE. On Unix and macOS this means those starting with a dot, and on Windows it's those set as hidden by using an NTFS attribute. This setting is only intended for special situations and is not to be confused with the next option which hides files based on metadata configuration within ES-DE.
You can mark games as hidden in the metadata editor, which is useful for instance for DOS games where you may not want to see some batch files and executables inside ES-DE, or for multi-disc games where you may only want to show the .m3u playlists and not the individual game files. By disabling this option these files will not be processed at all when ES-DE starts up. If you enable the option you will see the files, but their name entries will be almost transparent in the gamelist view to visually indicate that they are hidden.
It's possible to trigger custom scripts for a number of actions in ES-DE, as is discussed [below](USERGUIDE.md#custom-event-scripts), and this setting decides whether this functionality is enabled.
If enabled, only ROMs that have metadata saved to the gamelist.xml files will be shown in ES-DE. This option is intended primarily for testing and debugging purposes so it should normally not be enabled.
The window manager desktop composition can adversely affect the framerate of ES-DE, especially on weaker graphics cards and when running at higher resolution. As such the desktop compositor is disabled by default, although the window manager has to be configured to allow applications to do this for the option to have any effect. Note that this setting can cause problems with some graphics drivers (notably the Nvidia proprietary drivers) so if you see strange flickering and similar after quitting ES-DE, then disable the setting. In case of such issues, make sure that the emulator is also not blocking the composition (e.g. RetroArch has a corresponding option).
Displays the framerate and VRAM statistics as an overlay. You normally never need to use this unless you're debugging a performance problem or similar. **Note:** As of ES-DE v1.2 the VRAM usage statistics is not accurate. This will be addressed in a future release.
Enabling or disabling the menu when the UI mode is set to Kid. Mostly intended for testing purposes as it's not recommended to enable the menu in this restricted mode.
With this setting enabled, there is a Quit menu shown as the last entry on the main menu which provides options to quit ES-DE, to reboot the computer or to power off the computer. With this setting disabled, there will simply be an entry to quit the application instead of the complete quit menu.
If the option _When to save game metadata_ has been set to _On exit_, the gamelist.xml files will be updated at this point. This applies also if the Quit menu is disabled and replaced by the _Quit EmulationStation_ entry.
This menu is opened from the gamelist view, and can't be accessed from the system view. The menu changes slightly depending on the context, for example if a game file or a folder is selected, or whether the current system is a collection or a normal game system.
You open the menu using the **Back** button, and by pressing **B** or selecting the **Apply** button any settings such as letter jumping using the quick selector or sorting changes are applied. If you instead press the Back button again or select the **Cancel** button, the menu is closed without applying any changes.
_The game options menu as laid out when opening it from within a custom collection, which adds the menu entry to add or remove games from the collection._
This provides a quick selector for jumping to a certain letter. If the setting to sort favorite games above non-favorites has been enabled, then it's also possible to jump to the favorites games by choosing the star symbol. Similarly if there is a mix of folders and game files in the system and folders are configured to be sorted on top, then it's possible to jump to the folders using the folder icon. If there are only folders or only favorite games for the system, these games and folders will be indexed by their first letters and the star and folder symbols will not be disabled in the quick selector.
This is the sort order for the gamelist. The default sorting shown here is taken from the setting _Default sort order_ under _UI settings_ in the main menu. Any sorting that is applied via the game options menu will be persistent throughout the program session, and it can be set individually per game system and per collection.
Choosing this entry opens a separate screen where it's possible to apply a filter to the gamelist. The filter is persistent throughout the program session, or until it's manually reset. The option to reset all filters is shown on the same screen.
With the exception of the game name text filter, all available filter values are assembled from metadata from the actual gamelist, so if there is no data to filter for the specific field, the text _Nothing to filter_ will be displayed. This for example happens for the _Completed_ filter if there are no games marked as having been completed in the current gamelist. The same happens if a metadata setting is identical for all games, such as all games being flagged as favorites.
Note that the _Alternative emulator_ filter only includes game-specific values that have been set using the metadata editor, the system-wide alternative emulators setting has no effect on this filter.
Be aware that although folders can have most of the metadata values set, the filters are only applied to files (this is also true for the game name text filter). So if you for example set a filter to only display your favorite games, any folder that contains a favorite game will be displayed, and other folders which are themselves marked as favorites but that do not contain any favorite games will be hidden.
This entry is only shown if the system is a custom collection. The way this works is described in more detail [below](USERGUIDE.md#custom-collections).
In the metadata editor, you can modify the metadata, scrape for game info and media files, clear the entry which will delete all metadata and game media files, or delete the entire game which also removes its file on the filesystem. When manually modifying a value, it will change color from gray to blue, and if the scraper has changed a value, it will change to red. When leaving the metadata editor you will be asked whether you want to save any settings done manually or by the scraper.
This is the name that will be shown when browsing the gamelist. If no sortname has been defined, the games are sorted using this field. If the scraper option _Search using metadata names_ has been enabled, this name will be used for scraper searches.
This entry makes it possible to change the sorting of a game without having to change its name. For instance it can be used to sort _Mille Miglia_ as _1000 Miglia_ or _The Punisher_ as _Punisher, The_. Note that the _Jump to..._ quick selector on the game options menu will base its index on the first character of the sortname if it exists for a game, which could be slightly confusing in some instances when quick jumping in the gamelist.
Rating in half-star increments. This can be set as such manually or it can be scraped, assuming the scraper service provides ratings (currently only ScreenScraper does). If an external scraper application such as [Skyscraper](https://github.com/muldjord/skyscraper) has been used that may set the ratings in fractional values such as three-quarter stars, then ES-DE will round them to the nearest half-star. When this happens, the rating stars will be colored green to notify that a rounding has taken place and a question will be asked whether to save the changes even if no other manual changes were performed.
A flag to indicate whether this is a favorite game. This flag can also be set directly from the gamelist view by using the _Y_ button (assuming the _Enable toggle favorites buttom_ option is enabled).
A flag to mark whether the game is suitable for children. This will be applied as a filter when starting ES-DE in _Kid_ mode. Although it's possible to also set this flag for folders, this will **not** affect the actual files inside those folders. It will instead only be used to display the Kidgame badge for the folders themselves.
A flag to indicate that the game is hidden. If the corresponding option has been set in the main menu, the game will not be shown. Useful for example for DOS games to hide batch scripts and unnecessary binaries or to hide the actual game files for multi-disc games. If a file or folder is flagged as hidden but the corresponding option to hide hidden games has not been enabled, then the opacity of the text will be lowered significantly to make it clear that it's a hidden entry.
A flag to indicate whether the game should be excluded from being counted. If this is set for a game, it will not be included in the game counter shown per system in the system view, and it will not be included in the system information field in the gamelist view. As well, it will be excluded from all automatic and custom collections. This option is quite useful for multi-file games such as multi-disc Amiga or Commodore 64 games, or for DOS games where you want to exclude setup programs and similar but still need them available in ES-DE and therefore can't hide them. Files that have this flag set will have a lower opacity in the gamelists, making them easy to spot.
Whether to exclude the file from the multi-scraper. This is quite useful in order to avoid scraping all the disks for multi-disc games for example. There is an option in the scraper settings to ignore this flag, but by default the multi-scraper will respect it.
This option will hide most metadata fields as well as any badges. The intention is to be able to hide the fields for situations such as general folders (Multi-disc, Cartridges etc.) and for setup programs and similar (e.g. SETUP.EXE or INSTALL.BAT for DOS games). It could also be used on the game files for multi-disc games where perhaps only the .m3u playlist should have any metadata values. The only fields shown with this option enabled are the game name and description. So using the description it's possible to write some comments regarding the file or folder, should you want to. Game images and videos will also still be displayed if this setting is enabled.
A statistics counter that tracks how many times you have played the game. You normally don't need to touch this, but if you want to, the possibility is there.
This entry provides a selection of controller icons that are built into ES-DE (although the theme set can override the actual graphics files). The selected icon will be displayed as a badge if the current theme set support badges. The gamelist can also be filtered based on the controllers, but apart from this the functionality is cosmetic and will not affect the actual emulators.
**Alternative emulator** _(files only)_
If the option _Enable alternative emulators per game_ has been enabled, there will be an entry shown where you can select between alternative emulators for the specific game. There is a similar _Alternative emulators_ entry under the _Other settings_ menu, but that will apply the selection to the entire game system. If you select an alternative for a specific game using the metadata editor, that will take precedence and override any system-wide emulator selection (the currently selected system-wide emulator will be clearly marked on the selection screen). The alternative emulators need to be defined in the es_systems.xml file, and if there are no alternatives available for the current system, this row in the metadata editor will be grayed out. If you select an alternative emulator and later remove its corresponding entry from the es_systems.xml file, an error notice will be shown on this row. In this case you have the option to remove the invalid entry. But even if there is an invalid entry, games will still launch using the default emulator while logging a warning message to the es_log.txt file. Apart from this, the emulator selection should hopefully be self-explanatory.
For game files, there will be five buttons displayed on the bottom of the metadata editor window, and for folders there will be four. These are their functions:
This will remove any media files for the file or folder and also remove its entry from the gamelist.xml file, effectively deleting all metadata. The actual game file or folder will however _not_ be deleted. A prompt will be shown asking for confirmation.
This will remove the actual game file, its gamelist.xml entry, its entry in any custom collections and its media files. A prompt will be shown asking for confirmation. The deletion of folders is not supported as that would potentially be dangerous, instead use the appropriate operating system tools to handle deletion of directories. Likewise, for directories that are interpreted as files (this functionality is described earlier in this document) the Delete button is disabled.
The game media viewer displays videos and images in fullscreen mode and is launched from the gamelist view by pressing the _X_ button.
If a game video is available, this will be played automatically when launching the viewer. The _left_ and _right_ buttons are used to navigate betweeen the game media files. By default the video will continue to play when browsing the images, but this can be changed with a setting as described earlier in this document.
The media viewer can display the _video, box cover, box back cover, title screen, screenshot_ and _miximage_.
The other settings for the media viewer are similar to what is available for the screensavers; the audio can be enabled or disabled, the video can be stretched to fill the entire screen and scanlines and blur can be rendered on top of it. For screenshots and title screens, scanlines can be rendered. All these options are configurable via the _UI Settings_ menu.
The Dim screensaver simply dims and desaturates the current view and Black will show a black screen. The Slideshow and Video screensavers are more interesting as they can display images and videos from your game collection. In addition to this, the Slideshow screensaver can be configured to only show images from a specified directory.
If the option _Enable screensaver controls_ has been activated, you can manually toggle the screensaver from the system view by pressing the _Back_ button. In addition to this, for the Slideshow and Video screensavers, the controls will allow you to jump to a new random image or video by using the _Left_ and _Right_ buttons on your keyboard or controller. It's also possible to launch the game currently displayed using the _A_ button, and the _Y_ button will jump to the game in its gamelist without starting it.
For the video and slideshow screensavers, an overlay can be enabled via the screensaver options that displays the game name and the game system as well as a star symbol if the game is marked as a favorite.
If the Video screensaver has been selected and there are no videos available, a fallback to the Dim screensaver will take place. The same is true for the Slideshow screensaver if no game images are available.
ES-DE provides two types of collections, **Automatic collections** and **Custom collections**, the latter being defined by the user. Collections are as the name implies only collections of games already present in your actual game systems, so they're basically grouping of games into convenient views. As such the use of collections is entirely optional, but especially the custom collection support is a very nice feature which is worth some effort to setup.
The automatic collections are named _All games, Favorites_ and _Last played_. The _All games_ collection simply groups all your game systems into one big list, _Favorites_ combines all your games marked as favorites from all your game systems, and _Last played_ is a list of the 50 last games you have launched.
These automatic collections can be individually enabled or disabled by going to the main menu, selecting _Game collection settings_ and then _Automatic game collections_.
These are collections that you create yourself. Examples could be grouping in genres like _Shoot em up_, _Fighting games_ etc. or perhaps a time period like _1980s_, _1990s_ and so on.
If the theme set supports it, you can create a custom collection directly from a theme. However, rbsimple-DE and modern-DE do not provide such themes as it's believed that grouping them together in a dedicated _Collections_ system is a more elegant solution. Especially since the theme set would need to ship with an almost endless amount of collection themes for whatever categories the users would like to use for their game collections.
So if you have enabled the option _Group unthemed custom collections_ (it's enabled by default), any collections you add will show up in the special _Collections_ system. Here you can access them just as you would access folders inside a regular gamelist. The amount of games per collection is shown in the description, and a random game is displayed each time you browse through the list. You can also quick jump to this random game by pressing the _Y_ button.
The collection will now be created and the collection edit mode will be entered. You can now add games to the collection by navigating to any gamelist and pressing the _Y_ button. Any number of games from any of your game systems can be added. A game can also be part of multiple collections, there is no real limit for this.
Removing games works the same way, just press _Y_ to remove it if it's already present in your collection. You can do this either from the gamelist where the game was added, or from the collection itself.
When you are done adding games, you can either open the main menu and go to **Game collection settings** and select the **Finish editing 'Platform' collection** or you can open the game options menu and select the same option there. The latter works from within any gamelist, so you don't need to first navigate back to the collection that you're editing.
You can later add additional games to the collection by navigating to it, bringing up the game options menu and choosing **Add/remove games to this game collection**.
The way that custom collections are implemented is very simple. There is a single configuration file per collection inside the folder `~/.emulationstation/collections`
Any changes to custom collections, for example adding or removing a game, will be immediately written to the corresponding collection configuration file.
If you copy or migrate a collection from a previous version of EmulationStation or if you're setting up ES-DE on a new computer, the collection will not be enabled by just copying its configuration file to the `~/.emulationstation/collections` directory. You always need to explicitly enable each collection via the menu.
If you're migrating from a previous version of EmulationStation that has absolute paths in the collection files, these will be rewritten with the %ROMPATH% variable the first time you make a change to the collection.
ES-DE is fully themeable, and although the application ships with the comprehensive rbsimple-DE and modern-DE theme sets, you can use any RetroPie-compatible EmulationStation themes as well. Just be aware that ES-DE has added additional theme functionality compared to the RetroPie fork and more still will be added in future versions. This means that you may not get the full benefits of the application if you're using a theme set which has not been updated specifically for ES-DE. Some themes may also look slightly different as bugs that were present in the RetroPie fork have been fixed. Also note that most Batocera and Recalbox themes are not compatible as these forks are quite different.
As a side comment, the terms _theme_ and _theme set_ are both used when talking about theming. The technically correct term for what you apply to the application to achieve a different look is a _theme set_ as it's a collection of a number of themes for a number of game systems. But in practice it doesn't matter as both terms refer to the same thing and the terms are used interchangeably in this guide.
Themes are most easily installed to your ES-DE home directory, i.e. `~/.emulationstation/themes`. By just adding the theme sets there, one folder each, they will be found during startup and you can then choose between them via the _UI Settings_ menu on the main menu.
For this example, we've downloaded the [Carbon](https://github.com/RetroPie/es-theme-carbon) and [Fundamental](https://github.com/G-rila/es-theme-fundamental) themes and uncompressed them to the ES-DE home directory:
We now have four entries in the Theme set selector in the UI settings menu, i.e. _rbsimple-DE, modern-DE, es-theme-carbon_ and _es-theme-fundamental_.
Although you place additional themes in your ES-DE home directory, the default rbsimple-DE and modern-DE themes are located in the installation folder. For example this could be `/usr/share/emulationstation/themes` or `/usr/local/share/emulationstation/themes` on Unix, `/Applications/EmulationStation Desktop Edition.app/Contents/Resources/themes` on macOS or `C:\Program Files\EmulationStation-DE\themes` on Windows.
So if you would like to customize the rbsimple-DE or modern-DE theme sets, simply make a copy of their directories to ~/.emulationstation/themes and then those copies will take precedence over the ones in the application installation directory.
There are numerous locations throughout ES-DE where custom scripts will be executed if the option to do so has been enabled in the settings. By default it's deactivated so be sure to enable it to use this feature.
**Note:** The following list is what the default es_systems.xml files and the rbsimple-DE and modern-DE themes support. These theme sets are very comprehensive, so if you're using another theme, it may be that some or many of these systems are not supported. ES-DE will still work but the game system will unthemed which looks very ugly.
Note as well that the list and corresponding es_systems.xml templates may not reflect what is readily available for all supported operating system. This is especially true on Unix/Linux if installing RetroArch via the OS repository instead of using the Snap or Flatpak distributions (or compiling from source code) as the repository versions are normally quite crippled.
The column **System name** corresponds to the directory where you should put your game files, e.g. `~/ROMs/c64` or `~/ROMs/megadrive`. This follows the RetroPie naming convention, with some additions for systems that are not supported on RetroPie. So if migrating from Batocera or Recalbox, check this carefully and rename your system folders as required or ES-DE will not be able to find your games.
Regional differences are handled by simply using the game system name corresponding to your region. For example for Sega Mega Drive, _megadrive_ would be used by most people in the world, although persons from North America would use _genesis_ instead. The same is true for _pcengine_ vs _tg16_ etc. This only affects the theme selection and the corresponding theme graphics, the same emulator and scraper settings are still used for the regional variants although that can of course be customized in the es_systems.xml file if you wish.
Sometimes the name of the console is (more or less) the same for multiple regions, and in those cases the region has been added as a suffix to the game system name. For instance `na` for North America has been added to `snes` (Super Nintendo) giving the system name `snesna`. The same goes for Japan, as in `megacd` and `megacdjp`. Again, this only affects the theme and theme graphics.
The **Default emulator** column lists the primary emulator as configured in es_systems.xml. If this differs between Unix, macOS and Windows then it's specified in square brackets, such as [UW] for Unix and Windows and [M] for macOS. If one or more of the platforms are not specified it means that the system is not available on those platforms. For example Lutris which only exists on Unix is marked with only a [U]. There is a special [W*] indication for Windows which means that you need to manually add the emulator directory to the operating system's Path environment variable. This is required as some emulators don't ship with proper installers but instead only as a zip file that can be extracted anywhere on the filesystem. However, if using the portable/ZIP release of ES-DE, then this is not applicable as all emulators placed inside the `Emulators` directory will be automatically found. Unless explicitly marked as **(Standalone)**, each emulator is a RetroArch core. A number of systems are marked as _Placeholder_ which means that although there is a configuration entry present, the actual emulator is not preconfigured. If you want to use such a system, you need to add a custom configuration yourself. The long term goal is to have these placeholders replaced with proper emulator configuration so all systems can be used without requiring manual setup.
The **Alternative emulators** column lists additional emulators configured in es_systems.xml that can be selected per system and per game, as explained earlier in this guide. This does not necessarily include everything in existence, as for some platforms there are a lot of emulators to choose from. In those cases the included emulators is a curated selection. In the same manner as the _Default emulator_ column, differences between Unix, macOS and Windows are marked using square brackets. Unless explicitly marked as **(Standalone)**, each emulator is a RetroArch core.
The **Needs BIOS** column indicates if additional BIOS/system ROMs are required, as should be explained by the emulator documentation. Good starting points for such documentation are [https://docs.libretro.com](https://docs.libretro.com) and [https://docs.libretro.com/library/bios](https://docs.libretro.com/library/bios)
For additional details regarding which game file extensions are supported per system, refer to the es_systems.xml files [unix/es_systems.xml](resources/systems/unix/es_systems.xml), [macos/es_systems.xml](resources/systems/macos/es_systems.xml) and [windows/es_systems.xml](resources/systems/windows/es_systems.xml). Normally the extensions setup in these files should cover everything that the emulators support. For systems that have alternative emulators defined, the list of extensions is a combination of what is supported by all the emulators. This approach is necessary as you want to be able to see all games for each system while potentially testing and switching between different emulators, either system-wide or on a per game basis.
If you generated the ROMs directory structure when first starting ES-DE, the systeminfo.txt files located in each game system directory will also contain information about the emulators and supported file extensions.
For CD-based systems it's generally recommended to use CHD files (extension .chd) as this saves space due to compression compared to BIN/CUE, IMG, ISO etc. The CHD format is also supported by most emulators. You can convert to CHD from various formats using the MAME `chdman` utility, for example `chdman createcd -i mygame.iso -o mygame.chd`. Sometimes chdman has issues converting from the IMG and BIN formats, and in this case it's possible to first convert to ISO using `ccd2iso`, such as `ccd2iso mygame.img mygame.iso` or in the case of BIN files `ccd2iso mygame.bin mygame.iso`.
MAME emulation is a bit special as the choice of emulator depends on which ROM set you're using. It's recommended to go for the latest available set, as MAME is constantly improved with more complete and accurate emulation. Therefore the `arcade` system is configured to use _MAME - Current_ by default, which as the name implies will be the latest available MAME version. But if you have a really slow computer you may want to use another ROM set such as the popular 0.78. In this case, you can either select _MAME 2003-Plus_ as an alternative emulator, or you can use the `mame` system which comes configured with this emulator as the default. There are more MAME versions available as alternative emulators, as you can see in the table below.
There are also other MAME forks and derivates available such as MAME4ALL, AdvanceMAME, FinalBurn Alpha and FinalBurn Neo but it's beyond the scope of this document to describe those in detail. For more information, refer to the [RetroPie arcade documentation](https://retropie.org.uk/docs/Arcade) which has a good overview of the various MAME alternatives.
In general .zip or .7z files are recommended for smaller-sized games like those from older systems (assuming the emulator supports it). But for CD-based systems it's not a good approach as uncompressing the larger CD images takes quite some time, leading to slow game launches. As explained above, converting CD images to CHD files is a better solution for achieving file compression while still enjoying fast game launches.
