What is Libretro?

Libretro is a simple but powerful developement interface that allows for the easy creation of emulators, games and multimedia applications that can plug stright into any libretro-compatible frontend. This development interface is open to others so that they can run these pluggable emulator and game cores also in their own programs or devices.

What is possible with libretro?

  • Play games (retro and more current ones)
  • Watch movies (through the ffmpeg libretro core)
  • Other stuff (augmented reality, etc) (experimental test cores that showcase camera and location API support)

With libretro, you can make cross-platform applications that can use rich features such as OpenGL, cross-platform camera support, location support, and more in the future.
