[[TOC]]

First startup and onboarding

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 reset the touch overlay setting as long as you have at least pressed the Begin setup button. 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 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 a few challenges with emulation on Android. Some emulators on the Google Play store have not been updated for a long time, 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 easy 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 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 API which makes it possible for ES-DE to temporarily provide storage access to the game file on launch. This means that most of the time no access permission needs to be setup in the emulator upfront. Access can however only be passed for single files, so for systems that support multi-file games such as disc-based games in .bin/.cue format SAF URIs are often used instead. For those emulators you will therefore 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.

Adding to the FileProvider API confusion is the fact that some emulators will only launch games when using this API even though they need to have scoped storage access setup within the emulator upfront. FPseNG and FPse are two examples of this. So there is unfortunately no definitive rule regarding the use of the FileProvider API, it all depends on how the emulator has implemented the functionality.

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
• DroidArcadia
• FPseNG (still needs scoped storage to be setup in emulator)
• FPse (still needs scoped storage to be setup in emulator)
• GBA.emu
• GBC.emu
• Lynx.emu
• MD.emu (genesis, mastersystem, megadrive, megadrivejp)
• NES.emu
• NGP.emu
• PCE.emu (pcengine, supergrafx and tg16 systems)
• Ruffle
• Swan.emu

Some of these emulators require BIOS files, so they still need to be configured before they can be used with ES-DE.

Splitting system directories across multiple storage devices

While it's possible to split the game system directories across multiple storage devices this is 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:

<system>
    <name>samcoupe</name>
    <fullname>MGT SAM Coupé</fullname>
    <path>%ROMPATH%/samcoupe</path>
    <extension>.dsk .DSK .mgt .MGT .sad .SAD .sbt .SBT .7z .7Z .zip .ZIP</extension>
    <command label="Speccy (Standalone)">%EMULATOR_SPECCY% %ACTION%=android.intent.action.VIEW %DATA%=%ROMSAF%</command>
    <platform>samcoupe</platform>
    <theme>samcoupe</theme>
</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 copy it 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 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):
https://gitlab.com/es-de/emulationstation-de/-/tree/stable-3.0/resources/systems/android

Here's an example of a custom es_systems.xml file that relocates the samcoupe system:

<?xml version="1.0"?>
<systemList>
    <system>
        <name>samcoupe</name>
        <fullname>MGT SAM Coupé</fullname>
        <path>/storage/719F-3A7F/ROMs/samcoupe</path>
        <extension>.dsk .DSK .mgt .MGT .sad .SAD .sbt .SBT .7z .7Z .zip .ZIP</extension>
        <command label="Speccy (Standalone)">%EMULATOR_SPECCY% %ACTION%=android.intent.action.VIEW %DATA%=%ROMSAF%</command>
        <platform>samcoupe</platform>
        <theme>samcoupe</theme>
    </system>
</systemList>

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.

Here's again an example for the samcoupe system:

<?xml version="1.0"?>
<systemList>
    <system>
        <name>samcoupe</name>
        <fullname>MGT SAM Coupé</fullname>
        <path>/storage/emulated/0/ROMs/samcoupe</path>
        <extension>.dsk .DSK .mgt .MGT .sad .SAD .sbt .SBT .7z .7Z .zip .ZIP</extension>
        <command label="Speccy (Standalone)">%EMULATOR_SPECCY% %ACTION%=android.intent.action.VIEW %DATA%=%ROMSAF%</command>
        <platform>samcoupe</platform>
        <theme>samcoupe</theme>
    </system>
</systemList>

If going for this configuration, adding samcoupe games to a custom collection would end up with something like the following:

%ROMPATH%/amiga/OoopsUp.lha
%ROMPATH%/amiga/PacMania.lha
/storage/emulated/0/ROMs/samcoupe/Manic Miner.zip
/storage/emulated/0/ROMs/samcoupe/Prince of Persia.zip

This is obviously a non-portable collection.

You can relocate as many systems as you want, you just need to place them all within the systemList tag pairs in ES-DE/custom_systems/es_systems.xml.

Launching native Android apps and games

As of ES-DE 3.0.2 there is experimental support for launching native Android apps and games from inside ES-DE. For the time being it does however require that you use a separate app to import your apps and games into ES-DE. But following this initial setup launching native apps and games works just like launching games for any other system.

First head to this GitHub repository and download the ES Applauncher APK:
https://github.com/schattenphoenix/es_applauncher/releases

Many thanks to Alex Pferdmenges for developing this app!

After installing the APK on your device and giving it the necessary permissions you'll see a list of your apps and you can classify the ones you want as games, and you can disable the ones you want to skip via the Game and Disable checkboxes on the right side of the screen. You can also choose to extract the icons for these apps and store them into one of the media folders inside the ES-DE/downloaded_media directory. The Media dir dropdown at the top of the screen lets you select the media type. It's generally recommended to use screenshots or covers or you can skip this step altogether as most of these icons are pretty low resolution anyway.

To populate the androidapps and androidgames system directories press the save icon in the upper right corner of the screen and select your ROMs directory from the selector interface. For example this could be ROMs directly on internal storage, or on your SD card. Just press the Use this folder button and the directories and files will be generated for you. Now you can start ES-DE and launch these apps and games directly.

Note that it seems like ES Applauncher has issues working correctly on some Android 10 devices.

It's also possible to scrape Android apps and games using ScreenScraper, but at the time of writing the amount of entries in their database is somehow limited. It's therefore encouraged to participate in improving this situation by contributing metadata and media to their database, this will benefit everyone in the long run.

A built-in import tool for native Android apps and games is also planned for a future ES-DE release.

Running ES-DE as the Android home app

To run ES-DE as the home app (launcher) you'll select it accordingly from the Apps section of the Android Settings app. When in this mode the ability to quit the app is completely disabled as it doesn't make sense to exit the home app. Therefore the Quit ES-DE entry on the main menu is removed and the Back button/back swipe exits app option in the Other settings menu and its corresponding functionality is disabled.

Apart from this it works as you'd expect, ES-DE will start automatically when rebooting the device and pressing the home button will return to ES-DE regardless of which app you have running.

If the operating system runs out of memory when a game is running it will kill ES-DE even if it's set as home app. If this happens ES-DE will reload whenever you return from the game or if you press the home button. This is simply how Android works.

Also be aware that the version check that runs on app startup may not be able to complete successfully when ES-DE is set as the home app, as the device may not have network connectivity enabled yet just after rebooting.

It's generally a very good idea to import your native Android apps into ES-DE prior to setting it as the home app, this way you can easily access things like the Settings app. Note however that even if you somehow lock yourself out of the system by setting ES-DE as the home app and not having any native apps added you can still always access the Settings app via the Android notification shade. On most devices you access this by swiping down from the top of the screen. After swiping down, just select the cogwheel icon to start the Settings app. From there you can change the home app to something else than ES-DE, should you need to.

Known ES-DE problems

• 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.
• Using a mounted USB storage device for the ES-DE and/or ROMs directories will lead to the configurator exiting after finishing the setup instead of launching ES-DE. Restarting ES-DE manually will lead to a successful startup. If the option to create the system directories was selected in the configurator then this will have to be executed again from inside ES-DE. Note that using a mounted USB storage device leads to a very crippled setup anyway, as for example RetroArch can't read any games from such devices (i.e. from the /mnt/media_rw/ directory tree). Only emulators supporting scoped storage will be usable in such a setup.

Emulator installation and setup

Below are specific instructions and considerations for all supported emulators.

RetroArch

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 Samsung Galaxy Store, Amazon Appstore or the F-Droid store.

https://retroarch.com
https://galaxystore.samsung.com/detail/com.retroarch
https://www.amazon.com/dp/B09753XRVF
https://f-droid.org/en/packages/com.retroarch

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 original Citra emulator project is no longer alive, but there is a fork that should work as a drop-in replacement. The Citra MMJ fork is also a viable alternative. Both of these emulators are available for download from their GitHub sites.

https://github.com/PabloMK7/citra/releases
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.

https://play.google.com/store/apps/details?id=com.fms.colem.deluxe

Dolphin

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.

https://play.google.com/store/apps/details?id=org.dolphinemu.dolphinemu
https://f-droid.org/en/packages/org.dolphinemu.dolphinemu
https://dolphin-emu.org/download

Dolphin MMJR and MMJR2

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:

https://archive.org/details/dolphin-and-citra-fork-backup

DraStic

This emulator can be installed from the Play store as a paid app. Note that it does not support launching of zipped game files.

https://play.google.com/store/apps/details?id=com.dsemu.drastic

DroidArcadia

This emulator can be downloaded directly from their website.

http://amigan.1emu.net/releases

DuckStation

The Play store version of this emulator is getting frequent updates and is therefore recommended.

https://play.google.com/store/apps/details?id=com.github.stenzek.duckstation

EKA2L1

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.

https://play.google.com/store/apps/details?id=com.epsxe.ePSXe

EX Plus Alpha emulators

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.

https://play.google.com/store/apps/developer?id=Robert+Broglia
https://github.com/Rakashazi/emu-ex-plus-alpha/actions

There are also some BIOS files and similar that are needed to run these emulators, and which can be downloaded from their website.

https://www.explusalpha.com/

Fake-08

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 downloading it 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 and it has to be renamed to fake08_libretro_android.so before you install it into RetroArch. Details on how to manually install cores in RetroArch can be found on the Internet, but the short version is to use the Install or Restore a Core entry in the Load Core menu. Fake-08 can be downloaded from their GitHub site.

https://github.com/jtothebell/fake-08/releases

Flycast

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).

https://play.google.com/store/apps/details?id=com.fms.fmsx
https://play.google.com/store/apps/details?id=com.fms.fmsx.deluxe

FPseNG and FPse

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.

https://play.google.com/store/apps/details?id=com.emulator.fpse64
https://play.google.com/store/apps/details?id=com.emulator.fpse

iNES

This emulator can be installed from the Play store.

https://play.google.com/store/apps/details?id=com.fms.ines.free

IrataJaguar

This Atari Jaguar emulator can be downloaded from their website. Just be aware that it's very old and has not been updated for modern Android releases, so it may be finicky on some devices or it may not work at all.

After installing the emulator, open it and go to the settings tab, then choose "Select ISO and BIOS directory" and navigate to the ROMs/atarijaguar folder. It seems like you also need to start the game from inside the emulator before you can run it from ES-DE. Starting a game will create a savestate file. If you now exit the emulator and run the game from ES-DE you'll see a list of savestate files, just select the correct one to start the game.

J2ME Loader

This emulator can be installed from the Play store or the F-Droid store, or it can be downloaded from their GitHub site.

https://play.google.com/store/apps/details?id=ru.playsoftware.j2meloader
https://f-droid.org/en/packages/ru.playsoftware.j2meloader

JL-Mod

This emulator can be downloaded from their GitHub site.

https://github.com/woesss/JL-Mod/releases

Lime3DS

This emulator which is forked from Citra can be downloaded from their GitHub site.

https://github.com/Lime3DS/Lime3DS/releases

MAME4droid 2024 and MAME4droid

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.

Note that for MAME4droid 2024 there's an exception when it comes to setting up the ROM path. Instead of selecting each separate system directory (as is done on most other standalone emulators) you must select the root of the ROMs directory tree. To change the ROM path open Settings in MAME4droid 2024, then select General and then Change ROMs path. After restarting the emulator choose External storage and then the ROMs directory which contains all your ES-DE system directories. If you instead choose a specific system directory like ROMs/arcade or ROMs/neogeo then only that specific system will work when launching games from ES-DE.

https://play.google.com/store/apps/details?id=com.seleuco.mame4d2024
https://play.google.com/store/apps/details?id=com.seleuco.mame4droid

Be aware that MAME4droid 2024 requires specific input configuration for some systems. For instance to navigate the mouse cursor when using touch input you'll need to got into the Settings menu, then Input, then Touch controller and change Mode to Analog Stick.

If using a physical controller for mouse input (via the thumbstick) then you will need to map the mouse buttons to physical controller buttons. You do this via the MAME input settings. Bring up the MAME menu by pressing both thumbsticks, or by pressing the Start and Coin buttons on the touch overlay. Go into Input Settings then Input Assignments (this system) where you can assign physical buttons to the mouse buttons.

For some systems you will need to explictly set the Start and Select buttons in the same fashion as when configuring the mouse buttons. Otherwise you'll not be able to start any games.

There are a few more things that you may need to configure for some systems, but that's beyond the scope of this document and should be covered by the MAME emulator documentation.

MasterGear

This emulator can be installed from the Play store as a paid app.

https://play.google.com/store/apps/details?id=com.fms.mg

melonDS

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.

https://play.google.com/store/apps/details?id=me.magnum.melonds

M64Plus FZ

This emulator can be installed from the Amazon Appstore or the Google Play store. The Pro version is recommended to avoid annoying ads.

https://www.amazon.com/dp/B09L5FB7T4
https://play.google.com/store/apps/details?id=org.mupen64plusae.v3.fzurita.pro
https://play.google.com/store/apps/details?id=org.mupen64plusae.v3.fzurita

Mupen64Plus AE

This emulator is very similar to M64Plus FZ and it can be downloaded from their GitHub automatic build system.

https://github.com/mupen64plus-ae/mupen64plus-ae/actions

My Boy! and My OldBoy!

These emulators can be installed from the Play store as paid apps. There are also free/Lite versions available 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.

https://play.google.com/store/apps/details?id=com.fastemulator.gba
https://play.google.com/store/apps/details?id=com.fastemulator.gbc

Nesoid

Nesoid is not available on the Play store but it can be installed from the F-Droid store, or it can be downloaded from their GitHub site.

https://f-droid.org/en/packages/com.androidemu.nes
https://github.com/proninyaroslav/nesoid/releases

NooDS

Although NooDS is available via the Play store that version does not allow game launching from ES-DE. To get that to work instead use the version from their GitHub site. Also note that this emulator does not support launching of zipped game files.

https://github.com/Hydr8gon/NooDS/releases

OpenBOR

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.

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

Panda3DS (pandroid)

This emulator is in early development and there currently seems to be no way to run a game directly from ES-DE. Instead the emulator GUI will be displayed on game launch and you will need to manually select the game from there. Note that the Android build of this emulator is named pandroid, but as the overall project name is Panda3DS it will be referred to as such in ES-DE. This emulator can be downloaded from their GitHub site.

https://github.com/wheremyfoodat/Panda3DS/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.

Play!

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.

Make sure that you press the Browse button in PPSSPP when you're adding scoped storage access to your games directory or you will not be able to launch any games from ES-DE.

Ruffle

This emulator can be downloaded from their GitHub site.

https://github.com/torokati44/ruffle-android/releases

Real3DOPlayer

This 3DO Interactive Multiplayer emulator can be downloaded from their website. Just be aware that it's very old and has not been updated for modern Android releases, so it may be finicky on some devices or it may not work at all.

You need to place the BIOS file in the game system directory, i.e. in the ROMs/3do folder. The file panafz10.bin with MD5 checksum 51f2f43ae2f3508a14d9f56597e2d3ce has been proven to work.

After installing the emulator, open it and go to the settings tab, then choose "Select ISO and BIOS directory" and navigate to the ROMs/3do folder. It seems like you also need to start the game from inside the emulator before you can run it from ES-DE. Starting a game will create a savestate file. If you now exit the emulator and run the game from ES-DE you'll see a list of savestate files, just select the correct one to start the game.

Redream

This emulator can be installed for free from the Play store and can later be upgraded to the Premium version from inside the application.

https://play.google.com/store/apps/details?id=io.recompiled.redream

ScummVM

ScummVM can be installed from the Play store. There are also daily builds available on their GitHub site. Such a build may be required to be able to launch games from ES-DE until the Play store version has been updated.

Skyline

This emulator is not in active development any longer, but the latest release can be found on archive.org.

https://archive.org/details/skyline-edge-all-versions

Speccy

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.

Visual Pinball

Although Visual Pinball is working fine on Android it's not possible to properly integrate it with a frontend, you'll instead need to install your tables inside the app and create dummy .vpinball files for your games in ROMs/vpinball and after launching a table from ES-DE you need to manually start it from inside the Visual Pinball GUI. There are more detailed setup instructions in the Visual Pinball section of the User guide.

You can download Visual Pinball from their GitHub automatic build system.

https://github.com/vpinball/vpinball/actions

Vita3K

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

Winlator

In order to use Winlator to run Windows games you need to use a specific fork named Winlator Cmod as mainline Winlator does not offer frontend support. However the official GitHub page of this fork has disappeared so it's not clear which is the official release and where it can be downloaded from. As there are now multiple builds floating around the Internet you'll need to do some web searches to find a reliable distribution.

There are two variants of the fork, Glibc and PRoot, both of which comes with some pros and cons with regards to compatibility and performance.

The following builds have been successfully tested with ES-DE:

Filename	Type	MD5 hash
cmod-v6-pre-release-v6fix1.apk	glibc	678c6edf341f17128b071daa9756c459
Winlator-7.1.3-glibc-cmod-v7fix5.apk	glibc	a3d935d7d09e7999c43511de333efbcc
Winlator-7.1.2-proot-cmod-v6.5-BETA.apk	proot	540fcc6faf1f0938d1bee3c85235d9ed

Consider these as examples only, there may very well be a lot of other builds that work fine with ES-DE.

It's beyond the scope of this document to describe how to install games in Winlator, but once it's done and you've created a shortcut to your game from inside the container you can export it via the Export for Frontend option in the Winlator user interface. This will generate a .desktop file that you can place in the ROMs/windows folder and launch from ES-DE.

Yaba Sanshiro 2

This emulator can be installed from the Play store. Note that only the paid Pro version supports game launching from ES-DE. Also note that .bin/.cue files can't be launched for the time being, only .chd files seem to work. This needs to be fixed in the emulator so nothing can be done in ES-DE to work around that limitation.
