Game Genie BIOS (Genesis)/en · the cutting room mirror

The first follow-up to the NES version of the popular cheat device, this one introduced such additional features as support for up to five codes and the built-in effects switch. And unlike their rivals, Sega actually gave this a license. Bless your hearts, Sega.
