* Play the original Pac-Man: At the game select screen press Up(x3), Down(x3), Left, Right, Left, Right, Left. If you did it correctly, the sound heard in both Pac-Man and Ms. Pac-Man when you gain an extra life will play, and Pinky will take Blinky's place on the Press Start screen. Press the Ms. Pac-Man Start button and you will play "Pac-Man". After the game is over, the original Pac-Man's attract mode sequence will run for one cycle.

* To toggle the built-in speedup, insert coins then enter the following sequence: Left, Right, Left, Right, Up(x3), Fire. If you did it correctly, the sound heard in both Pac-Man and Ms. Pac-Man when you eat a bonus fruit item will play. This will toggle the speed in both Ms Pac-Man & Pac-Man as well as provide a 'Fast Shot' in Galaga.

Play Galaga for free: During the Galaga demonstration, wait until the Galaga Commander uses the tractor beam. Before it sucks up the ship, press fire and kill it. You now have total control and can play the sample level. However, finish quick or an error screen will come up. The game will function normally though.
