PCSX is a WIP for RetroNX and there are some compatibility issues that may occur:
-If the game has five or more .bin files, loading the .cue will crash your console. This is NOT alleviated by using different file formats such as .pbp, .m3u, or converting multi-bin games into single-bin games. Sometimes loading the first .bin file will get the game going, but there are side effects, such as no cd music.
-There is an included config specifically for PCSX that includes the base settings for best performance. This must be renamed to "retroarch.cfg" for these settings to take effect. Or you can change them manually to match the settings listed in the spreadsheet linked below.
-For specific game compatibility, please check the the Compatibility Spreadsheet linked here.
-If you have specific questions about PCSX, please refer to the libretro doc here. Info about bios, supported file formats, and so on can be found there.
