Description
Centipede was Atari’s another massive arcade hit and an instant classic. With over 50 thousand total games produced, it was one of the most commercially successful games from the golden age of arcades.
As with all Atari games of that period, Centipede has a unique pinout. While the original game uses a trackball, the game itself is capable of accepting normal joystick inputs, greatly simplifying the conversion to JAMMA. The joystick and button controls are buggy and do not work properly in cocktail mode with some board revisions.
