Regen is a new Sega Mega Drive / Genesis emulator for Windows (although there is a Linux port) developed by AamirM and aimed at maximum accuracy. Its compatibility is probably at or near 100% for licensed games. In terms of accuracy, all system components are accurately emulated to the last detail, and AamirM considers that Regen already runs many games even more accurately than Kega Fusion.
