RALibretro is a multi-emulator that can be used to develop RetroAchievements.

The "multi-emulation" feature is only possible because it uses libretro cores to do the actual emulation. What RALibretro does is to connect the emulation to the tools used to create RetroAchievements.


RALibretro is a Work-in-Progress!!!

Currently the development is going on this repo:
