libretro-atari800

Libretro port of the Atari800 emulator — Atari 8-bit computers (400/800/600XL/800XL/130XE/XEGS) and the Atari 5200 console.

The bundled Atari800 core is version 5.2.0. The upstream emulator is maintained by the Atari800 Development Team (see atari800/DOC/CREDITS) and is released under the GPL (see atari800/COPYING).

Controls

Four controllers are supported when the emulated system is set to 400/800 — useful for games such as M.U.L.E.; see the Atari 4+ player list.
