(There's no video for Generator/MacOS yet. Please contribute to MR and add a video now!)
Generator is a Sega Genesis emulator made originally by James Ponder and ported to the Macintosh platform by Richard Bannister. It supports full sound emulation, with accurate emulation of both the YM2612 FM chip and the SN76489 PSG. Two different video rendering engines are provided; one for maximum speed, and one for accuracy.
