The Atari 2600's port of Namco's Pac-Man was released in 1982. Controlled with Atari's famous 'Joystick', the player guides 'Pac-Man' through a maze while avoiding four ghosts; Blinky, Pinky, Inky & Clyde. The game was programmed by Todd Frye for the 2600 console. Frye managed to complete the game in record time and did it inspite of the limitations of the hardware. Unfortunately the game did not live up to expectation and was a major flop for Atari. This game was followed by Mrs. Pacman and Pacman Jr. (which is a much better game).
