It contains the three games Galaxian (1979), Ms. Pac-Man (1981), and Galaga (1981). Galaxian resembles the Famicom port instead of it representing the original arcade game. Galaga is cropped into a "window" while the status (lives, score, etc.) is moved into the background. Ms. Pac-Man resembled Tengen's ports of the game and even included the extras from their ports (like multiple sets of mazes, simultaneous multiplayer, etc.).
