Game Genie - Nintendo NES
The Game Genie attaches to the end of the NES cartridge, causing the cartridge to protrude from the console when fully inserted, making the depression impossible. Therefore, the Game Genie was designed in such a way that it did not need to be depressed in order to start the game. This design put even more stress on the LIF socket than standard game insertion, bending pins and eventually causing units to be unplayable without the Game Genie present.
The design of the Game Genie also made it very difficult to insert into a newer top-loading NES without pressing very hard. An adapter was created to deal with the problem, which Galoob offered to Game Genie owners free of charge, but few were requested, and the stock was liquidated.
There also exists a version of the Game Genie for the Family Computer, distributed by Realtec and sold in areas where Famiclones were common
