With a few simple changes to the emulator source code, almost any existing emulator could become a libretro core. RetroArch then handles the input (controls) and output (graphics and audio) while the emulator core handles the emulation of the original system.
RetroArch and libretro provide a way to take an existing emulator and load that emulator as a library or 'core'.
RetroArch is the official front end for the libretro API. Universal Controller Calibration & Mapping Using xboxdrvĮxample Per-System Control Override retroarch.cfgĬonvert RetroPie SD Card Image to NOOBS Image
