**Note:** This document is intended as a quick start guide, for more in-depth information and details on how to compile EmulationStation and perform more advanced configuration, please refer to the [INSTALL.md](INSTALL.md) document.
Getting started with EmulationStation is very easy, just make sure to install the software properly, either manually as built from source code or using one of the supplied packages. On Windows you'll use the installer instead of a package.
The installation procedure will not be covered here as it differs between operating system, so please refer to your operating system documentation for information regarding this topic. EmulationStation Desktop Edition is currently supplied as .deb and .rpm packages for Linux and as a standard NSIS installer for Windows.
On Unix this defaults to /home/\<username\>/.emulationstation/, on macOS /Users/\<username\>/.emulationstation/ and on Windows C:\Users\\<username>\\.emulationstation\
A settings file, **es_settings.cfg** will be generated with all the default settings, and a **es_systems.cfg** file will also be copied from the program resource folder. This file contains the game ROM and emulator settings and can be modified if needed. For information on how to do this, refer to the [INSTALL.md](INSTALL.md) document.
There's a log file in the home directory as well named **es_log.txt**, please refer to this in case of any errors as it should provide information on what went wrong.
After ES finds at least one game file, it will populate that game system and the application will start. If there are no game files, an error messsage will be shown, explaining that you need to install your game files into your ROM directory. You will also be given a choice to change the ROM directory if you don't want to use the default path. Please refer to the game installation procedure below in this document for more information regarding this.
When first starting ES, the application will look for any attached controllers (joysticks and gamepads). If no devices are found, it will be assumed that only keyboard navigation is to be used and the default keyboard mappings will be applied. It's recommended to change these default values, and a message will be displayed describing just this. It's however possible to hide this notification permanently and continue to use the default keyboard mappings indefinitely if you're happy with them.
If a controller is attached when starting ES and no **es_input.cfg** input configuration file exists, you will be presented with the input configuration dialog. Just follow the steps as described to map the inputs.
If an es_input.cfg configuration file exists, you will not be presented with the input device configuration screen as that would normally just be annoying. If you however need to configure a device to control the application (i.e. you've replaced your controller), you can do so by starting ES with the command line argument **--force-input-config** or you can manually delete the es_input.cfg file prior to starting the application. Alternatively you can navigate to the menu using your keyboard and select **Configure input** manually to configure your new device.
The actual procedure to map the inputs should be self-explanatory, just follow the on-screen instructions.
Both new and old devices can be (re)configured at any time by pressing the Start button and choosing "CONFIGURE INPUT". New devices will be appended to the existing input configuration file, so your old devices will retain their configuration.
When starting EmulationStation with the default settings, you will see the main screen first. From here you can navigate your game systems and enter their respective gamelists. If there are no game systems installed, you will not see this screen but rather an error message will be displayed, informing you that no games could be found.
Depending on the theme, the system navigation carousel can be either horizontal or vertical. The default theme rbsimple-DE provides horizontal navigation, i.e. you browse your systems be scrolling left or right.
Upon startup with the default settings, ES is set to the gamelist view style to **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 will be selected. Note that this automatic selection is applied per game system.
Also 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 very ugly indeed.
In additions to the styles just described, there is a **Grid** view style as well, but as of version 1.0.0 this is very limited and not recommended. Future versions of EmulationStation may update this style to a more useful state.
There is a help system available throughout the application that provides an overview of the possible actions and buttons that can be used. It's possible to disable the help system for a somewhat cleaner look using a menu option. Note that some general button actions are never shown, such as the ability to quick jump in gamelists, menus and text input fields using the shoulder and trigger buttons.
The help system will provide an overview per screen on the navigation options for the application, however here is a general overview. These are the inputs you mapped in the previous input device configuration step. Note that this is not an exhaustive list, but it covers most situations.
For most systems, this is very straightforward, just put your game files into the folder corresponding to the platform name. (These names can be found at the end of this document.)
Let's start with the simple scenario of a single ROM game file per platform, which is the case for the majority of systems. In this example we're setting up ES to play Nintendo Entertainment System games.
The supported file extensions are listed in [es_systems.cfg_unix](resources/templates/es_systems.cfg_unix) and [es_systems.cfg_windows](resources/templates/es_systems.cfg_windows).
Here is the snippet from the es_systems.cfg_unix file:
It's highly recommended to use filenames that are corresponding to the full name of the game, or otherwise you will need to manually feed the scraper the game name when scraping which is very tedious.
The default game directory folder is ~/ROMs. On Unix this defaults to /home/\<username\>/ROMs/, on macOS /Users/\<username\>/ROMs/ and on Windows C:\Users\\<username\>\ROMs\.
Assuming the default ROM directory is used, we need to create a directory corresponding to the \<path\> tag in es_systems.cfg, in this example it's **nes**.
That's it, start ES and the NES game system should be populated. You can now scrape game information and media for the games, and assuming you've setup RetroArch correctly with the FCEUmm core, you can launch the games.
For some systems, there are sometimes (or always) multiple gamefiles 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-disk images as this simplifies the disk swapping in the emulator. It's then this .m3u file that should be selected for launching the game.
It's of course also possible to skip this type of directory structure and put all the games in the root folder, but then there will be multiple entries for the same game which is not so tidy. Another approach would be to put all the files in the root folder and the hide the game files, showing only the .m3u playlist. But it's probably quite confusing to start a game that looks like a single-disk game and then be prompted for disk swaps by the emulator.
When setting up games in this fashion, it's recommended to scrape the directory in addition to the .m3u file as it looks nicer to see images and metadata for the games also when browsing the folders. ES fully supports scraping folders, although some metadata is not included for folders for logical reasons. If you only scrape the folders and not the actual game files, it looks ok when browsing, but when a game is part of a collection, the metadata and images will be missing there. This includes the **Last played** and **All games** collections for instance. Also note that while it's possible to mark a folder as a favorite, it will never be part of a collection, such as **Favorites**.
As well it's recommended to set the flags **Exclude from game counter** and **Exclude from automatic scraper** for the actual game files so that they are not counted (the game counter is shown on the system view) and not scraped if running the multi-scraper. It's enough to scrape the .m3u playlist file and the game folder. But if you only intend to manually scrape file-per-file then you don't need to bother with this.
Not all systems are as simple as described above, or sometimes there are multiple ways to configure the systems. So specifics to such systems will be covered here. Consider this a work in progress though as there are many systems supported by ES.
For all the supported MAME variants as well as Final Burn Alpha/FinalBurn Neo and Neo Geo, single file archives should be used. However these should retain the MAME names as filenames since ES ships with MAME lookup tables, meaning the MAME names are expanded to the full game names.
This is used by the TheGamesDB scraper where the expanded file name is 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.
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-disk 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-disk images as this simplifies the disk swapping in the emulator. It's then this .m3u file that should be selected for launching the game.
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 computer. So this means one folder per game in ES. 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 (the binary or a .bat batch file). This is done so that the game counter on the system view screen 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. Both of these fields can be set using the metadata editor.
Apart from this the game should work as normal. 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 **Last played**, **Favorites** and **All games** as well as any custom collections will miss the game metadata and media. If you don't have these collections activated, then this can of course be skipped.
Ports are not really executed using emulators, but is instead software running natively on your 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 of course possible to add these as single files to the root folder, but normally it's recommended to setup a separate folder per game as there may be more than a single file available per game. You very often want to have easy access to the game setup utility for instance.
For steam, it's recommended to put shell scripts/batch files directly in the root folder, where the file names of these scripts correspond 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:
EmulationStation 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.cfg** 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.cfg file, please refer to the [INSTALL.md](INSTALL.md) document which goes into details 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.
In order to use the default es_systems.cfg file, for Unix and Windows you need to make sure that the emulator binary directory is in the operating system's path variable. On Unix systems this is normally not an issue as a package manager has typically been used to install the emulator, and there is a standardized directory structure. But for Windows you may need to add the emulator directory to your %PATH% variable manually. If on Windows, a simple test is to open a command window and type the name of the emulator and press enter, if the emulator is not found, then EmulationStation won't find it either and you need to update your %PATH% variable.
As an alternative, if the emulator is not in your search path, you can either hardcode an absolute path in es_systems.cfg or use the %ESPATH% variable to set the emulator path relative to the EmulationStation location. Again, please refer to the INSTALL.md document on details regarding this.
For macOS the emulator directory is normally not an issue as there is a somehow standardized installation structure, and the es_systems.cfg template for this operating systems has absolute paths defined for the emulators.
Scraping means downloading metadata and game media files (images and videos) for the games in your collections.
EmulationStation Desktop Edition supports the two scrapers ScreenScraper.fr and 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 is an overview of what's supported by ES and these scrapers:
| Media type or option | ScreenScraper | TheGamesDB |
The category **Other game metadata** includes Description, Release date, Developer, Publisher, Genre and Players.
There are two approaches to scraping, either for a single game from the metadata editor, or for many games and systems using the multi-scraper.
### Single-game scraper
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. The metadata editor is explained in more depth later in this guide so it won't be covered here.
### Multi-scraper
The multi-scraper is launched from the main menu, it's the first option on the menu actually. Here you can configure a number of scraping options, all which are explained in more depth below when covering the main menu entries.
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 just removing some extra characters such as disk information or other data from the search name yields a better result.
In general the actual file name of the game is used for the scraper, the exception being MAME/arcade games when using TheGamesDB, as the MAME names are then expanded to the full game names.
Hopefully the scraping process should be self-explanatory once you try it in ES.
### Manually copying game media files
If you already have a library of game media (images and videos) you can manually copy it into ES.
The default directory is ~/.emulationstation/downloaded_media/\<game system\>/\<media type\>/
Remember that on Unix files are case sensitive, and as well the file extensions must be in lower case, i.e. .png intead of .PNG or .Png or the file won't be found.
As an alternative, you can also locate your game media in the ROM directory. This is explained below in this guide under the option **Display game art from ROM directories**. This is however not recommended and the built-in scraper will never save any game media to this folder structure.
Note that it's possible to change the game media directory from within ES, see the option **Game media directory** detailed below.
This menu can be accessed from both the main screen and from the gamelist views. It contains the scraper, the quit menu as well as the application settings. When it comes to saving settings, this is done automatically when navigating back from a screen, or when closing the menu altogether.
Whether to scrape the names of the games. This does not affect the actual files on the filesystem and is only used for viewing and sorting purposes. The downloaded media files are also matched against the actually game file on the filesystem, not against this name.
It's possible to set a flag per file to indicate that the file should be excluded from the multi-scraper. With this flag it's possible to override this setting and scrape all files anyway.
If this settings is enabled and a directory has its flag set to be excluded from the scraping, then the entire folder contents are skipped when running the multi-scraper.
**Scrape actual folders**
Enabling this option causes folders themselves to be included in the scraping. This is useful when games are grouped into folders that should themselves be scraped. For instance for DOS games or any multi-disk games where there is a folder for each game.
Defaults to Full which enables all functionality within the application. If set to Kid, only games marked as being suitable for children will be displayed, and there will be an option to disable the menu. In Kiosk mode, most settings are disabled.
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.
Whether to place all folders on top of the gamelists. If done so, the folders will not be part of the quick selector index, meaning they can no longer be quick-jumped to. Also, if this option is enabled, folders marked as favorites will not be sorted above non-favorite folders.
After how many minutes to start the screensaver. If set to 0 minutes, the automatic screensaver will be deactivated. It can however still be started manually, if the Screensaver controls settings is activated.
This includes the ability to start the screensaver manually, but also to browse Left and Right between images or videos, and to launch the game shown by the screensaver using the A button.
Enable or disable 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 will fall back to built-in sounds.
Handles collections, which are built using the games already present for your game systems. _(Details on how this works are discussed later in this guide.)_
If the theme set in use provides themes for custom collections, then this can be selected here. For example, there could be themes for _"Fighting games"_ or _"Driving games"_ etc. As of version 1.0.0, the default rbsimple-DE theme set does not provides such themes for custom collections.
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 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.
Enables the system name to be shown in square brackets after the game name, for example "CONTRA [NES]" or "DOOM [DOS]". It's recommended to keep this option enabled.
The amount of video RAM to use for the application. Defaults to 128 MiB which seems to work fine most of the time. The allowed range 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 edit the es_settings.cfg file manually, ES will log a warning and automatically adjust the value within the allowable range.
This gives you a choice between Normal and Borderless modes. With the borderless being more seamless as the ES window will always stay on top of other windows so the taskbar will not be visible when launching and exiting from games. It will however break the alt-tab application switching of your window manager.
The metadata for a game is updated both by scraping and modifying data in the metadata editor, but also when launching a game, as the play count and last played date is then updated. This settings enabled 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. In theory "On exit" will give some performance gains, but it's normally recommended to leave the setting at its default value which is "Always".
Here you can override the directory to your game media, i.e. the game images and videos. The default location is "~/.emulationstation/downloaded_media".
If enabled, you can override the launch command defined in es_systems.cfg on a per-game basis. It's only recommended to disable this option for testing purposes, such as when a game won't start and you're unsure if it's your custom launch command that causes the problem.
Allows hiding of hidden files, which on Unix means files and directories starting with a dot, and on Windows it's directories set as hidden as an NTFS option.
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.
If enabled, only ROMs that have metadata saved to the gamelist.xml files will be shown in ES. This option is intended primarily for testing and debugging purposes so it should normally not be enabled.
Using this option, you can locate game images in the ROM directory tree. The images are searched inside the directory "\<ROM directory\>/\<system name\>/images/" and the filenames must be the same as the ROM names, followed by a dash and the image type. For example "~/ROMs/nes/images/Contra-screenshot.jpg" and "~/ROMs/nes/images/Contra-marquee.jpg". This option is mostly intended for legacy purposes, if you have an existing game collection with this media setup that you would like to open in ES. The scraper will never save files to this directory structure and will instead use the standard media directory logic. It's recommended to keep this option disabled unless you really need it since it slows down the application somewhat.
Displays the framerate and VRAM statistics as an overlay. You normally never need to use this. **Note:** As of version 1.0.0 the VRAM usage statistics is not accurate; this issue will be addressed in future ES versions.
Gives the ability to hide the "Reboot system" entry on the quit menu. Anyone who has accidentally rebooted a system from such a menu will appreciate this.
Gives the ability to hide the "Power off system" entry on the quit menu. Anyone who has accidentally powered off a system from such a menu will appreciate this.
This menu is opened from the gamelists, and can't be accessed directly from the main screen. The menu changes slightly depending on the context, namely whether a game file or a folder is selected, and whether the current system is a collection or a normal game platform.
You open this menu by pressing the **Select** key.
This provides the ability to jump to a certain letter using a quick selector. If the setting to sort favorite games above non-favorites has been selected (it is enabled by default), then it's also possible to jump to the favorites games by choosing the star symbol. If there are only folders or only favorite games in a certain game list, these games and folders will be indexed as well, making it possible to jump betwen them using the quick selector.
This is the sort order for the gamelist. There's is a global sort order setting that can be changed in the main menu, and it's this sort order that is also shown here unless it's been modified during the program sessions. The sort order is persistent per game system throughout the program session.
### Filter gamelist
Choosing this entry opens a separate screen where it's possible to apply a filter for the gamelists, which is persistent throughout the program session, or until the filter is reset. The option to reset the filter is also shown on the separate screen.
### Edit this game's metadata / Edit this folder's metadata
This opens the metadata editor, which will be described in detail below.
### Add/remove games to this game collection
This is only shown if the system is a collection. This will also be described in more detail below.
## Metadata editor
In the metadata editor, you can modify the metadata for a game, scrape for game info and media files and delete media files or the entire game.
The following entries can be modified:
**Name**
This is the game that will be shown when browsing the gamelist. If no sortname has been defined, the games are sorted using this field.
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"_.
Usually provided by the scraper although it's possible to update this manually or write your own game description.
**Rating**
Ratings in half-star increments. Can be set as such manually or be scraped, if the scraper service provides ratings (currently only ScreenScraper does).
**Release date**
Release date in ISO 8601 format (YYYY-MM-DD).
**Developer**
Developer of the game.
**Publisher**
Publisher of the game.
**Genre**
One or multiple genres for the game.
**Players**
The amount of players the game supports.
**Favorite**
A flag to indicate whether this is a favorite. Can also be set directly from the gamelist by using the **Y** key.
**Completed**
A flag to indicate whether you have completed this game.
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, configuration tools etc. If a file or folder is flagged as hidden but the correponding option to hide hidden games has not been set, then the opacity of the text will be lowered significantly to make it clear that it's a hidden game.
A flag to indicate whether the game should be excluded from being counted. It's only used for the game system counter on the main screen, but is quite useful for multi-file games such as multi-disk Amiga or Commodore 64 games, or for DOS games for configuration executables that you want to keep in ES and therefore can't hide. Games 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-disk games for example. There is an option in the scraper settings to ignore this flag, but by default the scraper will respect it. Note that the manual single-file scraper will work regardless of whether this flag is set or not.
This option will hide most metadata fields in the gamelist view. The intention is to be able to hide the fields for situations such as general folders (Multi-disk, Cartridges etc.) and configuration files and similar (e.g. SETUP.EXE or INSTALL.BAT for DOS games). It could also be used on the game files for multi-disk 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. Using the description it's possible to write some comments regarding the file or folder, should you want to. It's still possible to display game images and videos with this setting enabled.
Here you can override the launch command for the game, for example to use a different emulator than the default for the game system. Very useful for MAME/arcade games.
**Play count**
A statistics counter that counts how many times you're played the game. You normally don't need to touch this, but if you want to, the possibility is there.
There is a screensaver built into ES with four different behaviours: _Dim_, _Black_, _Slideshow_ and _Video_.
There are numerous options for the screensaver, refer to the Main menu section above to find out about them.
The _Dim_ screensaver simply dims the current view and _Black_ will show a black screen. The _Slideshow_ and _Video_ screensavers are a bit more interesting as they can display images and videos from your game collection. (In addition to this, Slideshow can be configured to only show images from a specified directory).
If the option **Screensaver controls** has been activated, you can manually toggle the screensaver from the system view by pressing the 'Select' key. In addition to this the controls will allow you to jump to a new random image video or by using the left and right buttons on your keyboard or controller, and it allows you to actually launch the game just shown by pressing the 'A' button.
ES provides two types of collections, automatic collections as well as custom collections defined by the user. Each collection can be individually enabled or disabled in the main menu.
Collections are, as the name implies, only collections of games already present games from your game systems and any given game can be part of as many collections as you want.
There are multiple settings for the game collections, but these are covered above in the 'Main menu' section so that information won't be repeated here.
### Automatic collections
These are **All games**, **Favorites** and **Last played**. The 'All games' collection simply groups all your game system 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**.
Note that you should only enable these collections if you really need them as they slow down the application quite significantly. By default these collections are therefore disabled.
### Custom collections
These are collections that you create yourself. Example of such collections could be grouping in genres like _Shoot 'em up_, _Fighting_ 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, as of version 1.0.0, rbsimple-DE does not provide such themes.
But if you have enabled the option **Group unthemed custom collections** (it's active by default), any collections you add will show up in the special 'Collection' system. Here you can access them just as you would access folders inside a regular game system.
To create a custom collection, go to 'Game collection settings' in the main menu and choose 'Create new custom collection'.
Select a name and press enter, let's use the name '1980s' for this example.
The collection will now be added and the collection edit mode will be automatically selected. You can now add games to your collection by navigating to any game system and adding a game by pressing the 'Y' key, just as you would normally do to flag the game as a favorite. Any number of games from any of your game systems can be added to your collection.
Removing games works in the same way, just press 'Y' to remove it if it's already present in your collection. You can do this either from the game system 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 '1980s' collection' or you can open the game options menu and select the same option there. The latter works from within any game system, you don't need to 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 collection are implemented is very simple. There is a folder for the collections in `~/.emulationstation/collections` with a separate file for each collection.
For this example a file will have been created named `~/.emulationstation/collections/custom-1980s.cfg`.
The file contents is simply a list of ROM files, such as the following:
Note that if you for example copy or migrate a collection from a previous version of EmulationStation or if you're setting up EmulationStation Desktop Edition on a new computer, even though you copy the files into the collections directory, they will not show up in the application. You always need to enable the collection in the menu. ES looks inside the es_settings.cfg file during startup to see which collections should be shown.
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. Be aware though that if at this time the ROM was not found by ES, the corresponding entry in the collections file will be deleted.
## Themes
ES is fully themeable, and although the application ships with the comprehensive rbsimple-DE theme set, you can replace it with a number of themes available from various locations on the Internet.
>>>
Somewhat confusingly the term 'theme' and 'theme set' are used to refer to the same thing. The correct term for what you apply to the application to achieve a different look is actually 'theme set' as it's a collection of a number of themes for a number of game systems. The supplied rbsimple-DE is an example of such a theme set. But in this guide and in other EmulationStation resources on the Internet, the term 'theme' is often used to refer to the same thing as a 'theme set'.
>>>
Note that this Desktop Edition fork adds additional features to the themes and more still will be added in the future. This means that you may not get the full benefit of the application if you're using a different theme set. But effort is spent trying to make sure that the application is backwards compatible with the available themes used by other ES versions, even with the limited functionality.
Themes are most easily installed in your ES home directory, i.e. `~/.emulationstation/themes`. By just adding the theme sets there, one folder each, they will be found by ES during startup and you're given an option to choose which one to use from the 'UI Settings' on the main menu.
Note that although you can put additional themes in your ES home directory, the default rbsimple-DE theme is located in your installation folder. For example this could be something like `/usr/local/share/emulationstation/themes` on Unix, `/Applications/EmulationStation.app/Contents/Resources/themes` on macOS or `C:\Program Files\EmulationStation\themes` on Windows.
Note: If you would like to customize the rbsimple-DE theme, simply make a copy of the complete rbsimple-DE directory to ~/.emulationstation/themes and then that copy of the theme will take precedence over the one in the application installation directory.
In this example, we've downloaded the Carbon and Fundamental themes and uncompressed them to the ES folder:
```
~/.emulationstation/themes/es-theme-carbon
~/.emulationstation/themes/es-theme-fundamental
```
You will now have three entries for the Theme set selector in the UI settings menu, i.e. rbsimple-DE, es-theme-carbon and es-theme-fundamental.
Here are some resources where additional theme sets can be downloaded.
There are numerous locations throughout ES 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.
On Windows, ES can be installed to and run from a removable media device such as a USB memory stick. Together with games and emulators this makes for a fully portable retro gaming solution. The setup is somewhat technical, please refer to the [INSTALL.md](INSTALL.md) document to see how it's configured.
For details regarding the systems such as which emulator or core is setup as default or which file extensions are supported, refer to the **es_systems.cfg** templates [es_systems.cfg_unix](resources/templates/es_systems.cfg_unix), [es_systems.cfg_macos](resources/templates/es_systems.cfg_macos) and [es_systems.cfg_windows](resources/templates/es_systems.cfg_windows).
**Note:** The following list is what the default es_systems.cfg files and the rbsimple-DE theme supports. This theme is very comprehensive, so if you're using another theme, it may be that some or many of these systems are not supported. EmulationStation will still work but the game system will not be themed which looks very ugly.
The column **Game system name** corresponds to the directory where you should put your game files, e.g. `~/ROMs/c64` or `~/ROMs/megadrive`.
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 people 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 modified in the es_systems.cfg file if you wish to.
Sometimes the name of the console is (more or less) the same for multiple regions, and in those circumstances the region has been added as a suffix to the game system name. For example 'na' for North America has been added to `snes` (Super Nintendo), as this is the minority region corresponding to around 7,5% of the world population. The same goes for Japan, as in `megacd` and `megacdjp`. Again, this only affects the theme and theme graphics.
