The Game Genie 2 was in the works in 1993. It could wipe saves of such games if the console was turned on while the Game Genie was inserted. One of Sega's requirements for being on the system was that it would be incompatible with games that require a save feature. It was available for all it's current systems and one was in development for Sega CD. Sega fully endorsed the Game Genie on all it's system. It was then released for SNES, Genesis, Gameboy, and Game Gear. Later versions of the Game Genie had the ability to hide Genie modifications from checksum routines.
This was partially successful but some could be bypassed with additional codes. Nintendo tried other methods to thwart the Game Genie, such as using ROM checksums in later titles to detect cheat modifications. Before the lawsuit was filed Galoob offered to make the Game Genie an officially liscensed product but was turned down by Nintendo. When Nintendo lost the lawsuit it was finally released in the US. It was sold openly in Canada with Galoob placing 'Thank You Canada' in their ads. The case was called Lewis Galoob Toys, Inc. It was met with strong opposition by Nintendo and it was prevented from being distributed in the US as a lawsuit was underway. The first Game Genie to be released was for the NES.
