Libretro is a simple but powerful development interface that allows for the
easy creation of emulators, games and multimedia applications that can plug
straight 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.

Flycast is a multi-platform Sega Dreamcast, Naomi, Naomi 2, and Atomiswave
emulator derived from reicast.
