Pac-Man Game System: Atari 2600/7800 Cheat Category: Cheat Game Company: Unknown Game Category: Unknown Hint, Cheat, Walkthrough:   Pac-Man ======= Enter escape-tunnel, quickly go up & down in tunnel a few times without coming out. Go down as your last move and Pac-Man will "wipe" into the screen. He can now move up & down in this vertical plane through the walls, but not sideways. Hey may eat vitamins and get killed by ghosts. (Not particularly useful, but interesting.) Frying can cause the walls to starting "glowing" at irregular intervals during the game. Game play is otherwise the same, but its pretty annoying (consider it another level of difficulty =)
