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.

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.

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, some games are not currently fully-playable using their default control schemes due to interferences between system shortcuts and required button combinations. The following games, while having this issue, remain fully-compatible as they allow the player to modify the controls in-game. In addition to a general Select + Start + A + B button combination that can be used to soft reset Game Boy and Game Boy Color games, several have game-specific button combinations that clash with the shortcut functionality of the FunKey S. While the majority of these are not required, they can nonetheless be accessed by modifying the control scheme of Gnuboy, the default Game Boy and Game Boy Color emulator, via a configuration file that adds additional mappings of Select and Start to the L and R buttons, respectively. 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 emulator controls. 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. The following is a list of Game Boy and Game Boy Color games with affected button combinations.

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.

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 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 visual glitching
Games listed below have been found to have visual 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 visual glitches
Games listed below have been found to have visual 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. As there is no set point at which the GBA games on the list crash, they are partially compatible, though it is recommended that the alternate, albeit slower, VBA Next emulator 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 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. 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 the slower, but more compatible, VBA Next emulator.

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 with incompatible control schemes
Due to the multipurposed nature of the Function and Select button, the following games are currently not fully-playable due to the interference of system shortcuts with button combinations required for gameplay.

Games that are unplayable
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 a third-party (though more CPU intensive and at times slower) GBA emulator. 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!

Excluding GBA Video and Classic NES (Famicom Mini) games, at least 96 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 102 games are on the following systems:

NES           2 PS1          4 Genesis       9 GBC          1 GB           1 GBA         64 SNES         21

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.
