Description

The Game Genie is a series of cheat systems designed by Codemasters and sold by Camerica and Galoob for the Mega Drive, Sega Genesis and Game Gear that modifies game data, allowing the player to cheat, manipulate various aspects of games, and sometimes view unused content and functions. It is known as the first example of consumer-friendly "game enhancement" by means of (temporarily) directly altering the binary code of a game.
