Mac OS X game console emulator : OpenEmu

You can play older console games by either purchasing a genuine console as Super Nintendo or Sega Genesis or you can play them using emulation and ROMs.  I remember when I was a kid, playing games using Nesticle NES emulator or zSNES Super Nintendo emulator, it was giving us ability to play infinite games.  Today I present you with a Mac OS X alternative emulator : OpenEmu.  In fact, OpenEmu is more like a framework on top of all console emulators, it simply make it easier for anyone who want to play any console game on their iMac or MacBook pros.
