Nintendo sued to keep this thing off shelves. Sega put its own Seal of Quality on the box instead. That's the entire story of how the Game Genie ended up on the Sega Genesis in 1992, and it's one of gaming's better legal footnotes.
The Game Genie was designed by UK studio Codemasters and sold in America by Lewis Galoob Toys, first launching for the NES in 1990. Nintendo went after it immediately, arguing in court that letting players alter their games created an illegal derivative work, and won a preliminary injunction that pulled it off American shelves for roughly a year. It never stopped selling in Canada though, and Galoob ran ads in gaming magazines at the time literally thanking Canada for keeping business alive while the US fight played out. Galoob won the actual trial in 1991, the Ninth Circuit upheld it in 1992, and the Supreme Court refused to even hear Nintendo's appeal in 1993. Galoob walked away with 15 million dollars in damages for a year of blocked sales, and the ruling became a genuine landmark in fair use law. It got cited almost immediately in Sega's own legal fight with Accolade over reverse engineering the Genesis itself, the same console this ad is selling for.
By the time Galoob brought the Game Genie to the Genesis in 1992, Sega had clearly drawn the opposite conclusion from watching that whole fight play out. Instead of suing, Sega handed the Genesis Game Genie its own official Seal of Quality, the exact stamp of approval Nintendo had refused to give its version. This release also came with real upgrades, including a power switch and activation light so you could toggle every code off without yanking the cartridge, plus the side effect of disabling the console's region lock entirely, letting owners run import games that would normally refuse to boot.
Across every platform it landed on, NES, SNES, Game Boy, Genesis, and Game Gear, the Game Genie family sold about five million units combined. One console fought it in court. The other one just put its name on the box.
