Sega GenesisEdit

Ever doing what Nintendon't, the Sega Genesis Game Genie featured a switch to enable and disable code functions during gameplay. In addition, this version was endorsed by Sega, being officially licensed. A side effect of the shape of the cartridge is that imported games can be played on the Genesis/Mega Drive it is plugged into, provided it is in the same television region.
