Crazy Kong is an arcade game created by Falcon, released in 1981 and is similar to Nintendo's Donkey Kong. Although commonly mistaken as a bootleg version, the game is officially licensed for non-US markets and is based on different hardware. The game retains all of the gameplay elements of Donkey Kong, but has all of the graphics redrawn and re-colorized. They were allowed to produce a certain amount of printed circuit boards (PCB) and were banned from exporting them. Falcon breached this agreement by producing more than 9000 excess units and also by exporting them to the US. On January 29, 1982, Nintendo terminated their license agreement. It had a second version called Crazy Kong Part II.
