Game Genie (Sega Game Gear)

The Sega Game Gear version of the Game Genie is a specialised "cheat cartridge" (or "video game enhancer") developed by Codemasters which allows the user to manipulate video games.

Though developed by Codemasters, distribution was handled by Camerica in Canada and Galoob in the United States (and Europe, with the help of third-party distributors). Following the controversy of a Nintendo Entertainment System version of the device - of which Nintendo unsuccessfully tried to block, the Game Gear (and Mega Drive enhancer) were adopted by Sega as officially licensed products.
