If you feel the provided auto-configuration could be better or has bugs, please open an issue and I'll take a look. Games support auto-configuration are listed in the src/gamedb/gamedb.json file, along with some information and the configuration required to play them.Ĭurrently, there's no way to change the auto-configuration settings short of recompiling the core after making the changes. Since configuring the core for each game can be a tedious task, 81-libretro now features auto-configuration.

You’re better off finding standalone emulators for those consoles. If you’re wondering where the cores for hit consoles like the Playstation 2 and GameCube are, the PS2 one is unavailable in Retroarch, while the GameCube one isn’t particularly stable.
