RetroArch

It’s easy to think of RetroArch as a game emulator, but with Libretro they are much more than that. Sure, users can take RetroArch and play old games on their mobile devices, but they can also be used to create games, emulators, and other multimedia apps.
 
Users can choose from a variety of menus, they can scan the system for available games, they can view database information about each game once added to a collection, they can build or remap buttons, and they can even use cheats.
 
As it stands right now, more than 80 programs are already supported by RetroArch and more are on their way.
