The $15 Million Lawsuit Nintendo Lost in Federal Court

In May 1990, toy maker Lewis Galoob took Nintendo to federal court over a gold pass-through adapter called the Game Genie. Engineered in Britain by Codemasters, the device intercepted the Nintendo Entertainment System's 8-bit data bus in real time to alter game code on the fly. Instead of backing down, Nintendo countersued under federal copyright law, secured a preliminary injunction that blocked U.S. sales for over a year, and posted an escalating $15 million cash security bond. This documentary breaks down the complete forensic, technical, and courtroom history of the Game Genie: from 6502-derived RP2A03 inline bus interception and 16-letter encoding to the 8-bit compare byte, the parallel Canadian court battle through distributor Camerica, the two-week trial over "Nintendo Culture" before Judge Fern M. Smith, and the landmark 1992 Ninth Circuit decision in Lewis Galoob Toys, Inc. v. Nintendo of America, Inc. Main Sources Primary Legal Authorities Lewis Galoob Toys, Inc. v.
