Open Emu – Game emulation for Mac OS X
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
* Gens/GS
adds support for Sega Genesis, Sega CD and Sega 32x
* Nestopia
adds support for NES/Famicom
* SNES9x
adds support for SNES and Super Famicom
* Visualboy
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.
Requirements
Open Emu requires Mac OS X 10.5 (Leopard) or greater (and is untested on incremental versions below 10.5.7). The Quartz Composer plugins require Quartz Composer.app to be present in /Developer/Applications. Install the Developer Tools from your OS X install discs or download them from developer.apple.com.
