Conversely, games with improved compatibility via the use of the default BIOS rather than the official PlayStation one have their listings highlighted in grey.

The fifth section of this article lists PlayStation games that have compatibility issues if the official PlayStation BIOS file is not added to the FunKey S as instructed here. Bold-formatted games that are also italicized require additional testing to see if a change of settings and/or emulators fixes their compatibility issue. While games in the first two sections should generally be played via the default emulators and those in the last two should generally be played via third-party emulators, any game listed in this article not marked in bold should have improved compatibility in at least one of the higher CPU usage third-party emulators. These categories list games that are glitch-free if configured correctly, slightly-glitched, heavily-glitched, and incompatible, respectively. As the compatibility of such games can range from fully-compatible to fully-incompatible, compatibility issues have been divided into four main categories based on severity: fully-compatible, fully-playable, partially-compatible, and incompatible.

This article lists games that have compatibility issues with the default FunKey S emulators.
