If we are to answer the question about: “What new video game device which helped kids cheat came out in 1991?”, then the answer is NONE OF THE ABOVE. This is because Game Genie, a video game device containing cheat systems, was originally released in 1990. So, if we are to change the year from 1991 to 1990, then we can choose the correct answer as letter B or Game Genie.
This video game device was designed by Codemasters and sold by Galoob and Camerica. The first release was made for the Nintendo Entertainment System (NES), then it was released to Super NES, Gameboy and Sega. Nintendo filed a case against Galoob in 1990 for allegedly violating the Nintendo copyright law, but the court ruled in favor of Galoob in 1991.
