List of games with compatibility issues

This article lists games that have compatibility issues with the emulators used on the FunKey S that may make it difficult or impossible to play them without the modification of the emulator or the game itself. This includes games that need to be patched to function properly, games with emulation issues, games that require hardware that the device's emulators do not support, and games that crash at startup or have significant graphical glitches that render them unplayable. As inaccuracies with the FunKey's GBA emulator, gpSP, cause several games to crash or experience severe graphical glitching, third-party (though more CPU intensive and at times slower) GBA emulators are an alternative option to improve GBA compatibility. As the games on this page are divided into sections based on the glitch that affects them, users searching for specific games should use their browser's text search feature to locate them. While PlayStation compatibility is relatively good, several emulation issues with a number of its games have been documented on this page as well. Before adding a PlayStation game to one this article's lists, however, test an alternate version of it to ensure that the issue is with the emulation of the game and not the game backup itself.

Fully-compatible games
This section lists games that are fully-compatible on the FunKey S, having no emulator-caused glitching if the instructions listed in each subsection are followed.

Games with region-specific glitches
The following table lists games that have a regional variant that glitches and another that doesn't. For the best experience, it is suggested to use the alternative regional variant listed below.

Games that require patching
The following table lists games that must be modified to be fully playable on the FunKey S. To avoid system shortcuts interfering with their custom button combinations, Boktai 2: Solar Boy Django and Boktai 3: Sabata's Counterattack also need game-specific .key files, as listed below.

Games that require an SBI file
The PAL regional variants of the following PlayStation games require the use of an .SBI file to function properly (any NTSC regional variants of these games, however, generally do not need the additional file). To configure one of these files for a specific game, download and unzip the linked-to file for that game and place it in the PS1 folder of the FunKey S alongside the ROM file(s) of that game. Ensure that each game's .SBI file has the same file name as that game's ROM file(s) (example.sbi for example.bin and example.cue). While the .SBI files of the most recent English language variant of games have been uploaded directly to The FunKey Wiki for convenient access, should you be using an alternate PAL variant of a game, additional .SBI files can be found here.

Games that require pre-existing save files
The following games crash during their opening sequences, so should be loaded with a pre-existing save (.SAV) file created in an external emulator. Once you load this save file onto the FunKey, navigate to it in the main menu of the game rather than going through the game's opening sequence.

Games that require a modified configuration file
The following games are not emulated properly by default. After changing settings in the automically-generated configuration (.cfg) file for each of those games, however, they can run normally on the FunKey S. For the convenience of users, zipped .cfg files can be downloaded here for each affected game. To install one of the following game configuration files, remove it from the .zip archive and place it in the \mnt\FunKey\.fceux\cfg location of the FunKey S file system. Ensure that the name of the configuration file matches the name of the game's ROM file and that any pre-existing configuration file for that game is deleted.

Games that require adapted controls
Due to the multipurposed nature of the Function and Select button, in rare cases game functionality enabled by button combinations can be impaired by system shortcuts. While most such shortcuts are non-essential to core gameplay, the ones that are cannot be played without adapted controls and have been highlighted in green. Depending on a game's system and functionality, there are a number of ways of improving control functionality and compatibility, with the primary method that works with all games being .key files that allow the controls of games to be remapped on a per-game or per-console basis. In the case of the .key files linked-to below, gameplay functionalities have been made compatible by removing the overlapping FN functionalities. In the interest of maintaining the most useful system shortcuts for use, in some cases shortcuts in .key files are manually remapped in a manner to prioritize screenshots, then aspect ratio swapping, then volume, then brightness, with zooming having the lowest priority level. Games with a ¹ symbol next to their .key file download have the zoom shortcuts removed, games with a ² symbol have both the zoom and brightness shortcuts removed, while games with a ³ symbol have the zoom, brightness, and volume shortcuts removed. The controls of Treasures in the Deep, a PlayStation game that requires the additional inputs made available by the combined use of FN and the shoulder buttons, have been further modified, with the shoulder and trigger inputs swapped with the directional inputs to allow for complete game compatibility. To use the a .key file, unzip and place it in the same FunKey S folder as the game it's for (the Wing Commander.key file goes in the SNES folder, for instance). As Game Boy and Game Boy Color games use fewer buttons, their interfering shortcuts have instead been relocated to the shoulder buttons, with mapping priority given to L2 and R2 to avoid the accidental use of shortcuts during gameplay (as these games are able to retain the use of all shortcuts, they are marked with a ⁰ symbol). Should you prefer to retain normal shortcut mappings for these games, another option for GB/GBC games specifically is the addition of secondary Select and Start mappings to the device's shoulder buttons. This can be accomplished by following the Game Boy palette tutorial on the FunKey S documentation website, as the same gnuboy.rc configuration file that modifies the Game Boy palette can also adjust the controls of the gnuboy emulator. For the convenience of users, a zipped pre-configured gnuboy.rc file can be downloaded here, which can optionally be modified with one's preferred Game Boy color palette as described in the tutorial linked-to above. While Final Fantasy VIII's in-game button remapping functionality makes a .key file non-essential in it's case, for the convenience of users one has been prepared and made available for download here. As an inversion of the shoulder and trigger buttons is all that is needed to make the game's control scheme fully-compatible, no system shortcuts have been removed from the game's .key file. While each game's .key file is correctly detected and used whenever that game is loaded from the main menu of the FunKey S, returning to a game after using the device's Instant Action feature currently results in the default system control scheme being mistakenly loaded. To restore game-specific controls, simply exit and reopen the affected game.

Games that temporarily freeze
The following games freeze during opening video sequences. To fix this, simply close and reopen the FunKey S when this occurs and the videos should continue normally. For Vampire Hunter D, simply press the Start button three times and the game will continue on normally.

Games with opposing directional button glitches
The following table lists games that have one or more glitches that occur when opposing directional buttons are pressed, something that cannot normally be done on original hardware. These glitches rarely affect gameplay substantially or permanently, but remain notable nonetheless.

Fully-playable games
This section lists games that are fully-playable on the FunKey S, but have a glitch that affects gameplay in some way. Sometimes these glitches are minor, such as transparency flickering or graphical glitches during instances of menu changing, while other glitches are more noticeable, such as slowdown or sporadic crashing. Unlike games listed in the incompatible games section, however, games listed here should be fully-playable from beginning to end without crashing, severe graphical glitches, or severe slowdown. If you find that any list in this article is missing a game or that one of the games listed works as intended, feel free to edit that list yourself or inform the wiki admin!

Games with slowdown
Games listed below have light to moderate slowdown, though not sufficiently severe to render them entirely unplayable.

Games with transparency glitches
In some games, transparency effects are mimicked by rapidly enabling and disabling a texture overlaying a background, making an object appear transparent if done rapidly enough. Emulation errors and differences in timing can at times diminish the effectiveness of this trick, rendering the flicking more visible than intended, creating a mildly unpleasant effect. Below is a list of games where such a glitch has been found.

Games with left edge graphical glitching
Games listed below have been found to have graphical glitching along the left edge of the screen at times. This glitch usually only occurs during certain portions of a game and does not significantly affect gameplay.

Games with menu-change graphical glitches
Games listed below have been found to have graphical glitching occur during infrequent instances of menu changes. As these glitches only occur during menu changes (and often only once or twice when a game is started for the first time), this type of glitch usually does not affect core gameplay.

Games with sporadic crashing
The following games have been found to crash sporadically during gameplay. Chrono Cross has been found to randomly get stuck on a black screen after closing the in-game menu. Videos illustrating the issue can be found here and here; the regular updating of save states and/or in-game saves to restore the game to is the recommended counter-measure. In addition to freezing sporadically when cutscenes are triggered, Roswell Conspiracies: Aliens, Myths & Legends also freezes if audio from the game's logbook is played. Thrasher Presents Skate and Destroy has been found to crash sporadically crash infrequently during gameplay, though this issue has so far not been found in the PAL variants of the game. As there is no set point at which the GBA games on the list crash, they are partially compatible, though it is recommended that one of the alternate, albeit slower, emulators be used with these games instead to entirely avoid the risk of crashing. If you decide to play these games in the default gpSP emulator, be sure to create regular save states as a means of reloading in case a crash does occur.

Games with non-sporadic crashing
The following games have been found to crash non-sporadically during gameplay. While the level of gameplay interference caused by non-sporadic crashing depends on the game, ranging from inconsequential in the case of Mortal Kombat 4 to frequent in the case of the homebrew Air Hockey, all of the following games nonetheless remain fully-playable.

Games with other graphical glitches
The following games have graphical glitches that do not fit into any graphical glitch category above. Graphical glitches in the following games range from barely to extremely noticeable, but none prevent the player from playing the game to completion. Should you find the graphical glitches in any of the GBA games listed below to be too severe, an alternative option is to play them in one of the slower, but more compatible, third-party emulators.

Games with audio glitches
The following games have audio glitches that affect gameplay to varying degrees.

Games with other issues
The following games have issues described in the fourth column that cannot be categorized in any of the categories above.

Incompatible games
Games listed below either do not run at all on the FunKey S or cannot be normally played beyond a certain point due to either a glitch or unemulated hardware. While the lists are sizeable, note that the number of games that function normally with little to no glitching is far higher, so if a game isn't listed below it will most likely run on the FunKey S. If you find that a game functions on the FunKey S but has a glitch of some sort, consult one of the lists above to see if that game is listed. If you find that a game is missing from any list in this article, please inform the the wiki admin.

Games that require unemulated hardware
The following table lists games that cannot be played on the FunKey S due to the requirement of hardware that the FunKey S does not currently emulate.

Games that are improperly emulated
The following table lists games that are unplayable in the emulators currently used on the FunKey S due to emulation issues. Most GBA games listed below, except those highlighted in yellow, can be still be played on the FunKey S through the use of one of the third-party (though more CPU intensive and at times slower) GBA emulators. While there is currently no alternative SNES emulator, the SNES emulator used by the FunKey S has a comparatively higher compatibility rate than the GBA emulator, with many of the incompatibilities listed below being due to the use of SNES enhancement chips in certain games. If you find that the list is missing a game or that one of the games listed works as intended, feel free to edit the list yourself or inform the wiki admin!

At least 148 licensed games are incompatible with the FunKey S due to emulation inaccuracies. Additionally, 6 homebrew releases have been found to be incompatible as well. The combined 154 games are on the following systems:

NES           1 SNES         21 SMS          1 PS1         32 Genesis       8 GBC          1 GB           1 GBA         89

While GBA Video, Classic NES (Famicom Mini), and GBA multi-pack games (highlighted in orange) are also listed, they are excluded from the above counts.

The following games appear to function correctly at first, but have been reported to eventually crash. If further testing confirms this, they will be moved to the main list above. If further testing disproves this, they will be removed from this list.
