Nintendo World Championships 1990 (1990)

The competition cartridge from Nintendo's 1990 touring championship, which gave players six minutes and 21 seconds to collect 50 coins in Super Mario Bros., finish a custom track in Rad Racer and then score as many points as possible in Tetris. Gray carts were used at the events, and Nintendo Power later gave away gold versions in a reader contest. Accounts of the numbers disagree, with 25 or 26 golds and gray figures that vary widely, and that uncertainty is part of the legend. Each gray cart carries a unique number, so with this one the provenance matters far more than the shell.
