List of third-party OPK applications/en

This article lists third-party OPK applications built for the FunKey S. Freely downloadable from this page, these applications allow users to add additional functionalities to their devices. To install an OPK application, simply create a new folder at the root of the FunKey S file system and place the OPK file in it. The application can subsequently be accessed from the Gmenu2x launcher, where it is sorted automatically by its type: application, emulator, or game. As the "Instant Action" feature of the FunKey S is limited to the emulators specifically optimized for it, it is recommended that users save their state in third-party programs before closing the system or returning to the system menu. Also note that OPK applications built for systems other than the FunKey S are incompatible with it and will not function without modification.

Applications
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.

Emulators
The following emulators add to the capabilities of the FunKey S by allowing emulation of several currently unsupported systems and improved emulation of several currently supported systems. To give users a sense of how well these emulators function, each is rated from low to high for both overall emulation accuracy and speed. To improve the CPS2 emulation of the libretro emulators below, this configuration file should be placed in the /mnt/FunKey/.sdlretro/cfg location of the FunKey S file system. For PC-FX emulation, a PC-FX BIOS file must be placed in the /mnt/Funkey/.pcfxemu location of the FunKey S file system.

Games
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 run Doom, a WAD, IWAD, or PWAD file is needed as well. To run VVVVVV, a data.zip file from the either the game's commercial or freeware release must be placed in the /mnt/FunKey/.local/share/VVVVVV location of the FunKey S file system. To run Wolfenstein 3D, all WL6 files from the game's commercial release must be placed in the /mnt/FunKey/.ecwolf location of the FunKey S file system.
