Nintendo created this special cartridge, which contains modified versions of Super Mario Bros., Rad Racer and Tetris, for use in the 1990 Nintendo World Championships. The three games are played in order, and specific goals must be met in order to progress. In Super Mario Bros., the object is to collect 50 coins. In Rad Racer, you must complete the first level. In Tetris, the only goal is to earn the highest possible score. Gameplay for all three games is limited to a total of six minutes.
According to tsr's NES Archive, only 116 copies of the cartridge exist (90 given to competition finalists, and 26 to the winners of a Nintendo Power contest).
