This unit contains Ms. Pac-Man, Galaga, Mappy, Xevious, and Pole Position. After Jakks Pacific introduced their proprietary GameKey expansion card concept, a revision of this model included a GameKey slot. Two GameKeys were released for this model: one with Dig Dug and New Rally-X and one with Pac-Man, Rally-X, and Bosconian. The GameKey-enabled model saves high scores.
Unit guaranteed to work.
