Cet article répertorie les applications tierces au format OPK conçues pour la FunKey S. Téléchargeables gratuitement à partir de cette page, ces applications permettent aux utilisateurs d'ajouter des fonctionnalités supplémentaires à leurs appareils. Notez, cependant, que comme la fonction d'enregistrement automatique d'action instantanée de l'appareil est implémentée programme par programme, les utilisateurs doivent se rappeler d'enregistrer manuellement leur progression dans tout programme tiers qui n'a pas implémenté la fonction de sauvegarde automatique. Notez également que bien que de nombreux appareils utilisent OPK comme format d'application, seules les applications OPK compilées spécifiquement pour la FunKey S sont compatibles avec celui-ci. Une fois qu'une application FunKey S OPK est téléchargée, elle peut être installée en la plaçant simplement dans un dossier à la dossiers Applications, Emulators et Native games disponibles par défaut pour la gestion des fichiers. Les applications disponibles en téléchargement sur cette page sont organisées comme elles seraient accessibles à partir du lanceur Gmenu2x - dans les trois groupes suivants :

Si vous souhaitez créer ou modifier vous-même des applications OPK, vous pouvez télécharger une version de SquashFS configurée pour éditer des applications OPK sur Windows ici. Après avoir extrait le dossier SquashFS de son archive ZIP, ajoutez le fichier OPK que vous souhaitez éditer dans le dossier et double-cliquez sur le fichier 1. EXTRACT_OPK.bat. Cela créera un dossier appelé squashfs-root, contenant des fichiers pour les paramètres de configuration de l'application, l'image de l'icône et les données binaires. Sauf si vous avez une expérience préalable de la configuration d'applications OPK, il est cependant recommandé de ne modifier que le fichier icône, un fichier image carré de 32 pixels au format PNG qui représente l'application dans Gmenu2x. Ce faisant, assurez-vous que le fichier d'icône de remplacement est également une image carrée de 32 pixels, au format PNG, et nommé exactement comme le fichier d'origine (icon.png est remplacé par icon.png). Une fois que vous avez fini de modifier l'application, retournez dans le dossier SquashFS et double-cliquez sur le fichier 2. MAKE_OPK.bat, qui appliquera vos modifications au fichier OPK soumis. Après l'apparition et la disparition de plusieurs fenêtres, votre application sera modifiée et prête à être renvoyée sur votre FunKey S. Notez que s'il y a plusieurs applications que vous souhaitez modifier, vous devez le faire une à la fois. Pour obtenir des instructions supplémentaires sur l'utilisation de SquashFS pour modifier ou créer des applications OPK, il est recommandé de rejoindre le Serveur Discord de la Communauté FunKey.

Although the wiki-hosted versions of the applications listed in this article are updated periodically, development repository links are also listed where applicable in case any of them have been updated in the interim.


The following applications are any programs for the FunKey S that are neither emulators nor games. Alongside each application is listed a general description of it.

Name Description Author(s) / Compiler(s) OPK
Gmenu2x Audio Fix Disables the audio amplifier while in the menu of Gmenu2x, preventing a buzzing sound from occurring. Drum78 Link
Clock Used to set the system's time for RTC functionality. Gameblabla Link
EasyRPG Interprets games made with RPG Maker 2000 and RPG Maker 2003. Download
Game Music Emu Music player that emulates the audio of several retro systems. Drum78 Download
KeyKalc Graphing calculator program. Robbi Blechdose Link
MPlayer Enables video playback in both original and stretched aspect ratios. NovemberJoy Download
Pocket CDG Karaoke and MP3 music player; matching MP3 and CDG (can be a blank text file should you just want to play MP3 files) are needed, with a song's CDG file used to play it. As non-standard MP3 file settings can cause music to be played too quickly, should this occur, you should "convert" the MP3 file to a standard MP3 format using a converter such as this.

The emulators listed in this section add to the capabilities of the FunKey S by enabling improved emulation of several supported systems and general emulation of several unsupported systems. As a means of helping users choose which emulators to use, especially for cases in which there are multiple options, the following table lists currently unsupported systems on the left with the best emulators currently available for them on the right:

MAME 2000
Stella 2014
FinalBurn Alpha
Neko Project II Kai
Fake 08

Should a system not be listed above, it is either already officially emulated by the FunKey S or has unofficial emulation that lacks sufficient functionality for use by a general audience. To illustrate cases of the latter, each emulator is rated from low to high for both overall emulation accuracy and speed. In addition to the emulators listed on this page, should you wish to emulate the BBC Micro, CHIP-8, or ZX Spectrum, meta-emulation is an additional option for third-party emulation. Should one of the emulators listed on that page be incompatible with the default gpSP emulator, however, the SDL Retro mGBA core or the standalone VBA Next emulator would be needed to use the meta-emulator.

SDL Retro

Two options for using SDL Retro are available: All-In-One and One-By-One.


As the first of these includes all default SDL Retro cores in the OPK file itself, all the user must do to install it onto their FunKey S is add it to a folder at the root of the device's file system just like any other application, emulator, or game.


Should you prefer to only have the emulator cores you intend to use installed, and thus speed up the SDL Retro's core selection process, you may alternatively download the One-By-One option.

While its download also includes an OPK file, the emulator cores themselves are included in a separate cores folder that must be placed in the /mnt/FunKey/.sdlretro file location of the FunKey S for SDL Retro to function.

BIOS File Location

If one or more required BIOS files are listed alongside a core you wish to use, ensure that those files are named and located in the /mnt/FunKey/.sdlretro/system file location for optimal emulation results.

Game Specific File Locations

  • In the case of blueMSX, download, extract, and place that emulator's Databases and Machines folders in the /mnt/FunKey/.sdlretro/system file location.
  • In the case of Neko Project II Kai, the required PC-9800 files listed in the table below should be placed in the /mnt/FunKey/.sdlretro/system/np2kai file location.

Can't See .sdlretro Folder

If you don't see the .sdlretro folder, your computer's Unix-based operating system is hiding hidden folders. To enable the viewing of such folders on MacOS, use the Shift+Cmd+Period key combination. To do so on ChromeOS, click the three-dot icon at the top-right of the Files application and select the Show hidden folders option.

If one or more required BIOS files are listed alongside an emulator, ensure that those files are named and located in the following file locations for optimal emulation results:

  • /mnt/FunKey/.3doh for 3DOh
  • /mnt/FunKey/.pcfxemu for PCFXEmu
  • /mnt/FunKey/.smsplus/bios for SMS Plus GX

If you choose to use the version of SMS Plus GX included in the SDL Retro OPK, follow the instructions listed in the section above instead. As PCSX ReARMed Ultimate and PicoDrive simply replace their default counterparts when initially loaded, their BIOS files (if not already present) go in the regular /mnt/PS1/bios and /mnt/Sega Genesis/bios file locations, respectively. Should you wish to instead add FinalBurn Alpha 2012, Gambatte, MAME 2000, or VICE to the SDL Retro OPK to lessen the number of icons present in the Emulator tab of Gmenu2x, you can alternatively download, extract, and place their SO format emulator core files in the /mnt/FunKey/.sdlretro/cores location of the FunKey S file system (if the cores folder is not already present, create it first). If you don't see the .sdlretro folder or the .3doh, .pcfxemu, or .smsplus folders disappear upon creation, your computer's Unix-based operating system is hiding hidden folders. To enable the viewing of such folders on MacOS, use the Shift+Cmd+Period key combination. To do so on ChromeOS, click the three-dot icon at the top-right of the Files application and select the Show hidden folders option.

The following applications are freeware games that have either been ported to or natively developed for the FunKey S. To facilitate list navigation and game selection, alongside each game is listed its genre. To play the OPK ports of commercial games, one or more additional files containing necessary copyrighted assets must be provided by the user from their own legally acquired copy of the game. The data files of such games should be grouped together in a folder located at that game's listed file location. Games requiring several of a specified file type to run have an asterisk placed after the applicable file type(s).

Make note of the following information for the following games:

  • While Doom, Doom II, and Final Doom only require a single WAD file each, add-on WAD files also can be used
  • While Quake only requires its PAK0.PAK file to launch, to access the full game, the PAK1.PAK file is also required
  • Due to a change made to the libvorbis package in the FunKey-OS V2.2.0 update, VVVVVV is currently non-functional when using the latest official system firmware. To fix this incompatibility without downgrading the firmware of one's device, a third-party firmware revision can be installed to fix the issue until the next official firmware update is released. Other changes made by the third-party firmware update include:
    • Adding UTF-8 support to Gmenu2x
    • Replacing swap usage with battery percentage on the system statistics overlay
    • Updating the PicoDrive (Sega Genesis/Mega Drive) emulator
    • Switching the default Game Gear emulator from Mednafen to PicoDrive
    • Adding Mona and the Witch's Hat Deluxe to the list of included homebrew Game Boy Color games
    • Removing a buzzing sound from Gmenu2x
As with official firmware updates, simply download and add this FWU file to the root folder of your FunKey S to install the update. Should you wish to flash this version of FunKey-OS directly onto a MicroSD card, an IMG file for the firmware revision is available here. Further instructions on the above processes can be found here and here, respectively.

If you don't see the .local folder, or the .cannonball, .eduke32 or .ecwolf folders disappear upon creation, your computer's Unix-based operating system is hiding hidden folders. To enable the viewing of such folders on MacOS, use the Shift+Cmd+Period key combination. To do so on ChromeOS, click the three-dot icon at the top-right of the Files application and select the Show hidden folders option.
