RALibretro
RALibretro is a multi-emulator that can be used to develop RetroAchievements and, of course, earn them.
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.
The integration with RetroAchievements.org site is done by the RAIntegration.
