This document contains information specific to the Android release, for more general ES-DE documentation refer to the [User guide](USERGUIDE.md) as well as the general [FAQ](FAQ.md).
It's also generally recommended to read the [Frequently Asked Questions (FAQ) for Android](FAQ-ANDROID.md) document prior to diving into the information in this document.
When you first start ES-DE you will be greeted by a welcome screen, this is part of the _configurator_, the ES-DE onboarding interface. The configurator is easy to use and will guide you through the necessary setup steps.
As a first step you need to give ES-DE the required storage access permission or it will not be able to function. Just enable the setting and the configurator will proceed to the next step. Next you will need to define a application data directory where your settings, scraped media, custom collections and so on will be stored. By default this will be placed in the _ES-DE_ directory in the root of your device's internal storage, and this directory will be created for you automatically.
After this step you need to select a ROMs directory where your game files will be stored, by default this will be named _ROMs_ and will be located in the root of you device's internal storage. You can however choose to place this on an SD card if you want to, just change the path using the Android file selector GUI. If you do change the path to the SD card you will however need to manually create the ROMs directory as well as to delete the empty directory that was created for you in the built-in storage.
The next step is optional, and it's whether to create the game systems directory structure inside your ROMs folder. Performing this will also create _systeminfo.txt_ files in each system directory. These files contain information about the system such as what file extensions and emulators that are supported. They are not mandatory for the app to function, they are only there for your convenience. In general it's recommended to create the system directories, although you could remove the ones you don't need afterwards for a slightly faster app startup speed.
This is basically the onboarding process, and ES-DE should now start up. Just be aware that you need to place at least one game with a supported file extension in the ROMs directory tree or ES-DE will only show an information dialog about missing games.
Also note that ES-DE does not install any emulators, you need to install those separately. There is more information about that topic later in this document.
If you need to re-run the configurator for some reason then the easiest way is to go into the Android Apps setting screen and revoke the storage access permissions under _Special app access_. This will make the configurator run automatically next time you start ES-DE. Another way to force it to start is to clear the app's storage under _Storage & cache_ but this is normally not recommended as it also deletes all themes you have downloaded using the theme downloader. A third option would be to rename either the ES-DE or ROMs directory as this will also trigger the configurator on next app startup.
## Touch input overlay
By default the touch input overlay will be enabled which makes it possible to use ES-DE without a controller or physical keyboard by overlaying virtual buttons on top of the ES-DE interface. If you are using a device which has a built-in controller you may however want to disable this feature. That is done via the _Enable touch overlay_ option in the _Input device settings_ menu on the main menu. Just be aware that disabling this option on a device where you have no other input method than touch will lock you out of the application.
If you accidentally disable the touch overlay you can force the configurator to run as explained in the previous section above, this will always reset the touch overlay setting. Another option would of course be to temporarily plug in a controller or keyboard to enable the setting via its menu entry. A third option would be to manually edit the es_settings.xml file in the ES-DE application data directory. The setting you are after is named _InputTouchOverlay_ which should be changed from _false_ to _true_.
Apart from this there are numerous options for the touch overlay, like the ability to change its size, opacity and fade-out time. Setting the fade-out to zero will make it permanently visible. See the [User guide](USERGUIDE-DEV.md) for a complete reference of all app settings and features.
## Retention of files and data
Almost all files saved and used by ES-DE are kept in the shared storage on either the device's built-in storage or on the SD card. This means that uninstalling the ES-DE app will not remove any of that data. The only thing that will be deleted are themes that have been downloaded using the built-in theme downloader, as it's not possible to store these in the ES-DE application data directory for technical reasons.
## Emulation on Android in general
There are some challenges with emulation on Android. Some emulators on the Google Play store have not been updated for a long time, or like in the case with RetroArch they are crippled to comply with Google's rules and policies. And some emulators are not available on the Play store at all. For these reasons you will need to sideload some manually downloaded APKs for a good emulation setup. There is a section later in this document describing the best place to get hold of each supported emulator.
Thankfully sideloading emulators is not very difficult to do, the exact producedure for how to install APKs manually is not covered here but there are many resources available online on how to accomplish this.
There is also the [F-Droid](https://f-droid.org/) app store as an alternative to Google Play, and this service contains a couple of emulators that are not present on the Play store, or that are present there but haven't been updated for a very long time.
A number of emulators support the [FileProvider](https://developer.android.com/reference/androidx/core/content/FileProvider) API which makes it possible for ES-DE to temporarily provide storage access to the game ROMs on launch. This means that no access permission needs to be setup in the emulator upfront. For those emulators which do not support the FileProvider API, you will generally need to manually provide scoped storage access to each game system directory. Note that it's not supported to give access to the root of the entire ROM directory for emulators that use scoped storage, it has to be for the specific system. For instance `/storage/emulated/0/ROMs/n64` rather than `/storage/emulated/0/ROMs`.
Some emulators like RetroArch are still using an older storage access method and for those emulators this is not something you need to consider.
The following emulators are configured for FileProvider access:
* 2600.emu
* C64.emu
* GBA.emu
* GBC.emu
* Lynx.emu
* MD.emu
* MAME4droid 2024
* MAME4droid
* NES.emu
* NGP.emu
* PCE.emu
* Play!
* Ruffle
* Saturn.emu
* Swan.emu
* Yuzu
Some of these emulators still require BIOS files, so not all of them will be completely free from manual configuration.
The following emulators have partial FileProvider access support but are currently not configured for that in ES-DE:
* Dolphin (the FileProvider interface is broken on some devices)
* M64Plus FZ (the FileProvider interface doesn't work reliably and game launching randomly fails when using it)
* PPSSPP (the FileProvider interface doesn't work with .chd files specifically)
## Splitting system directories across multiple storage devices (not recommended)
While it's possible to split the game system directories across multiple storage devices this is definitely not recommended. First it's tedious to setup, but more importantly it breaks portability for the installation. For instance you can't easily migrate between the different operating systems that ES-DE support and your custom collections will not be portable at all, as they will instead contain absolute paths to your games.
The way ES-DE works is that you have a defined ROMs directory which corresponds to the %ROMPATH% variable that is used throughout the es_systems.xml file and the custom collections files. For example this is the system configuration for the samcoupe system:
Here the path tag is using the %ROMPATH% variable to keep it relative to the base ROMs directory as selected via the onboarding configurator when you first installed ES-DE. If you relocate your ROMs directory to a different storage device, or to another device altogether or if you synchronize your games across Android and Linux, macOS or Windows then everything will still work correctly.
Similarly custom collection files contain the %ROMPATH% variable too, such as this:
```
%ROMPATH%/amiga/OoopsUp.lha
%ROMPATH%/amiga/PacMania.lha
%ROMPATH%/samcoupe/Manic Miner.zip
%ROMPATH%/samcoupe/Prince of Persia.zip
```
This makes your custom collections portable if you move your ROMs directory and you can also transfer the collections between various devices and operating systems while keeping everything working seamlessly.
If you still insist on relocating some game system directories to another storage device then you need to make custom system configuration entries for them. See the _Game system customization_ section of the [User guide](USERGUIDE.md#game-system-customizations) for details on how this is accomplished. In short you need to create an es_systems.xml file in the ES-DE/custom_systems directory and replace the %ROMPATH% variable with an absolute path for the specific systems you want to relocate.
You can find the bundled es_systems.xml file for Android here (which contains configuration for all supported systems):\
This example points the samcoupe directory to the external storage device /storage/719F-3A7F which may for instance be an SD card.
Note that doing the opposite, i.e. placing your primary ROMs directory on external storage and relocating a specific system to internal storage requires you to use the /storage/emulated/0 path, you can't use /sdcard in the path tag.
There are two serious issues that seem to be specific to the Ayn Odin 2, although it remains to be seen whether the problem exists also on other devices.
The first problem is that some emulators refuse to run games that you place inside directories that contain dots in their names. This is quite problematic as the [directories interpreted as files](USERGUIDE.md#directories-interpreted-as-files) functionality depends on the ability to add file extensions to directory names.
This has been observed with M64Plus FZ, Play!, Saturn.emu, FPse and FPseNG and it's working fine with RetroArch, NetherSX2, ePSXe, DuckStation and Yuzu. Note however that this is not a complete list as not all emulators have been tested for this problem.
If you run into this issue you can use the _folder link_ functionality as an alternative to the _directories interpreted as files_ functionality. How to use folder links is described in the [User guide](USERGUIDE.md).
The second problem is that a number of emulators can't be launched from ES-DE at all. When attempting to run such an emulator an error popup with the game name followed by "ERROR CODE -1" is displayed. The affected emulators are ColEm, fMSX, iNES, MasterGear, My Boy!, My OldBoy!, Redream and Speccy.
The following devices have been tested and do **not** experience either of these two problems:
* Ayn Odin Lite (Android 11)
* Retroid Pocket 4 Pro (Android 13)
* Google Pixel 4a (Android 13)
* Google Pixel Tablet (Android 14)
There are also some issues with sound quality on the Odin 2, such as large fluctuations in volume where some sounds are quite loud and some are quite silent. There are also some strange aliasing effects when playing samples rapidly.
## Known ES-DE problems
In addition to the issues specific to the Ayn Odin 2 there are a couple of other problems that will hopefully be resolved in the near future:
* Poor performance/low frame rate after startup on some devices, which seems to happen randomly and is usually resolved by itself within 10 to 30 seconds.
* The Android soft keyboard causes rendering issues when navigating using a controller or physical keyboard, as such the ES-DE built-in keyboard is enabled by default for the time being. For testing purposes the Android soft keyboard can be enabled via the _Enable virtual keyboard_ option in the _UI settings_ menu. If only using touch input the issue is not present. This problem is believed to be caused by a bug in the SDL library so it probably needs to be resolved there.
## Emulator installation and setup
Below are specific instructions and considerations for all supported emulators.
The RetroArch release from the Google Play store is problematic. It does not contain all emulator cores and a number of people have reported issues launching games from ES-DE (apparently it doesn't work at all on some devices). For these reasons it's strongly recommended to use the 64-bit release from the RetroArch website instead, or to install it from the Amazon Appstore or the F-Droid store.
Be aware that you need to manually install every core you want to use from inside the RetroArch user interface, and you also need to install all necessary BIOS files. The Android release of RetroArch is pretty unforgiving and will usually just present a black screen on game launch if the core file or the BIOS file is missing, and it will hang there until Android realizes the app is not responding and displays a popup where you can choose to kill the process.
### AetherSX2 / NetherSX2
Although the emulator entry is named AetherSX2 the recommended release of this emulator is actually the NetherSX2 patched version as the AetherSX2 release on the Google Play store doesn't work correctly and probably can't be used with ES-DE at all. You'll need to search for this APK online, the filename you'll want is `15210-v1.5-4248-noads.apk`
If you prefer to apply the NetherSX2 patch yourself (i.e. build the APK) then you can find all relevant information here:
https://github.com/Trixarian/NetherSX2-patch
### Citra
The version of Citra on the Google Play store is very old and barely works. Instead download either the Canary or Nightly builds from the Citra website or use the Citra MMJ fork:
https://citra-emu.org/download \
https://github.com/weihuoya/citra/releases
### ColEm
This emulator can be installed from the Play store. There is a paid version as well named ColEm Deluxe (ColEm+ ColecoVision Emulator is the store listing name).
Although this emulator supports both the Adam and ColecoVision systems it can unfortunately not do both interchangeably. In order to play Adam games you need to go into the Emulation settings in ColEm and tick the _Coleco Adam_ box. And likewise you'll need to untick it any time you want to play a ColecoVision game. This is true for launching games from ES-DE as well as starting them from inside the emulator GUI.
The Play store version is somehow up to date and could be used, otherwise the F-Droid store version is up to date, or you could download the latest release directly from their website.
Although it's not normally recommended to use the unofficial Dolphin forks because they are mostly ancient and have been surpassed by the mainline Dolphin releases, there could still be situations where it's useful. For example on weaker devices where the older release would work better.
There are multiple MMJR forks in existence, but the ones supported by ES-DE are `Dolphin.MMJR.v11505.apk` and `MMJR.v2.0-17878.apk` which can be downloaded from here:
This emulator can be downloaded from their GitHub site.
https://github.com/EKA2L1/EKA2L1/releases
There does not seem to be a way to launch individual EKA2L1 games from a frontend application on Android, instead ES-DE will simply launch the EKA2L1 user interface and you'll have to manually start your game from there.
### ePSXe
This emulator can be installed from the Play store as a paid app.
These set of emulators also known as the "Robert Broglia" emulators consist of 2600.emu, C64.emu, GBA.emu, GBC.emu, Lynx.emu, NEO.emu, NES.emu, NGP.emu, MD.emu, MSX.emu, PCE.emu, Snes9x EX+, Saturn.emu and Swan.emu
You can install them via Google Play (as paid apps) or download them from their GitHub automatic build system.
This RetroArch core is a good port of the official PICO-8 game engine which does not exist on Android. It's not shipped with RetroArch by default though so you need to manually install it. After download you'll need to place the core inside's RetroArch's downloads directory and then install it from the RetroArch app. You must use the 64-bit version with the filename `libfake08-arm64.so`. Details on how to manually install cores in RetroArch can be found on the Internet. Fake-08 can be downloaded from their GitHub site.
Flycast is not available on the Play store or the F-Droid store, but it can be downloaded from their GitHub site.
https://github.com/flyinghead/flycast/releases
### fMSX
This emulator can be installed from the Play store. There is a paid version as well named fMSX Deluxe (fMSX+ MSX/MSX2 Emulator is the store listing name).
These emulators can be installed from the Play store as a paid apps. FPseNG is the more modern version so it's probably best to go for that. Note that these emulators do not support .chd files.
These emulators can be installed from the Play store. It's strongly recommended to go for the _MAME4droid 2024_ version as this is updated with a recent MAME release while the older _MAME4droid_ is using an ancient MAME release.
This emulator can be installed from the Play store but it's quite buggy. Every time you add a new game to the ROM directory you need to start the emulator and manually refresh the game list or you won't be able to launch the game from ES-DE.
These emulators can be installed from the Play store as paid apps. There are also free/Lite versions availble for these emulators but they have not been updated in years and don't run on modern devices. As such they are not supported by ES-DE.
Although OpenBOR is working fine on Android it's not possible to properly integrate it with a frontend, you'll instead need to install your game PAKs into the `/sdcard/OpenBOR/Paks` directory and create dummy .openbor files for your games in `ROMs/openbor` and after launching a game from ES-DE you need to manually start it from inside the OpenBOR GUI. There are more detailed setup instructions in the _OpenBOR_ section of the [User guide](USERGUIDE-DEV.md#openbor).
You can download OpenBOR from their GitHub site, the version named _OpenBOR v3.0 Build 6391_ has for example been proven to work well.
https://github.com/DCurrent/openbor/releases
### Pizza Boy GBA and Pizza Boy GBC
The Pizza Boy GBA and Pizza Boy GBC emulators can be installed from the Play store. There are Basic (free) versions and Pro (paid) versions available.
As of writing this, the Basic version of the GBA emulator does not seem to be able to launch games from ES-DE, but the Pro version is working fine. Both the Basic and Pro versions of the GBC emulator are working correctly.
This PlayStation 2 emulator can be downloaded from their website.
https://www.purei.org/downloads.php
### PPSSPP
The Play store version of this emulator is getting frequent updates and is therefore recommended. There is a paid Gold version as well which is functionally identical to the free version.
This emulator can be installed from the Play store. There is a paid version as well named Speccy Deluxe (Speccy+ ZX Spectrum Emulator is the store listing name).
Although this emulator supports both the Sinclar ZX Spectrum and MGT SAM Coupé systems it can unfortunately not do both interchangeably. In order to play SAM Coupé games you need to go into the Emulation settings in Speccy and select _Sam Coupe_ from the _Computer Model_ selection screen. And likewise you'll need to change it back any time you want to play a ZX Spectrum game. This is true for launching games from ES-DE as well as starting them from inside the emulator GUI.
This PlayStation Vita emulator can be downloaded from their GitHub site. Refer to the User guide for detailed game setup instructions.
https://github.com/Vita3K/Vita3K-Android/releases
### Yuzu
The Play store version of this emulator is getting frequent updates and is therefore recommended. There's an Early Access version as well which is also recommended.
