The Game Genie: How an Unlicensed NES Accessory Revolutionized Gaming

"We didn’t have a license to create Nintendo games so we found a way of bypassing Nintendo’s lock-out chip and released games that way. We had an idea of placing a switch on the cartridge to add extra lives, weapons, and things like that. Then we made the mental leap of saying that if we could do this with our own games, then maybe we could build an interface for other people’s games too. It was a game that morphed into an industry."— David Darling

"For an unlicensed game accessory, the Game Genie sure casts a long shadow. It reshaped the games we already owned—and had a profound effect on copyright law."
