Joust is an arcade game published by Williams Electronics that was released on July 16, 1982. Atarisoft officially released only two Joust games under the Atarisoft name, which are the Apple II and IBM PC versions. Besides the two computers, Atarisoft had plans to release the game on more systems like the BBC Micro, ColecoVision, Intellivision, etc. However, the ports (except for the Apple and IBM release) were all cancelled before released. As of June 2021, the only two prototypes that were dumped online are the ColecoVision port and the Commodore 64 port. [1]
