OpenEmu 2.0.5


OpenEmu is an open source project to bring game emulation to OS X as a first class citizen, leveraging modern OS X technologies such as Cocoa, Core Animation and Quartz, and 3rd party libraries like Sparkle for auto-updating.


OpenEmu is based on a modular architecture, allowing for game-engine plugins, this means OpenEmu can support a host of different emulation engines and back-ends while retaining a familiar OS X native front-end.


Currently OpenEmu can load the following game engines as plugins:

  • Atari 2600 (Stella)
  • Atari 5200 (Atari800)
