Regen

Regen is a new Sega Mega Drive/Genesis emulator for Windows (although there is a Linux port) developed by AamirM, written for maximum accuracy. The compatibility is probably at or near 100% for licensed games. About the accuracy, well, Regen already runs many games even more accurately than Kega Fusion. Everything has been accurately emulated to the last detail.
