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

Currently Open Emu can load the following game engines as plugins:

  • CrabEmu - adds support for Sega Master System, Game Gear, SG - 1000
  • Gambatte - adds support for Game Boy and Game Boy Color
  • Genesis Plus - adds support for Sega Genesis/Mega Drive
  • NeoPop - adds support for Neo Geo Pocket and Neo Geo Pocket Color
  • Nestopia - adds support for NES/Famicom
  • FCEU - adds support for NES/Famicom
  • SNES9x - adds support for SNES and Super Famicom
  • BSNES - adds support for SNES and Super Famicom
  • Visualboy Advance - adds support for Game Boy Advance

Open Emu also supports high quality scaling with Open GL, multi-threaded video and audio playback as well as individual features and preferences per game engine, such as NTSC video signal emulation for the Nestopia core.

Minimum system requirements:

  • OS X 10.7
  • Core 2 Duo Processor
  • GMA X3100 Graphics
