D. Scott Williamson, self-proclaimed Atari fanatic and former Atari employee, has started a Kickstarter campaign to fund production and distribution of a cartridge version of Star Castle for the Atari 2600.
Star Castle, a 1980 Cinematronics arcade game, was planned for release on the Atari 2600 but was never released. Williamson completed his own port of Star Castle for the Atari 2600 in 2010, which received a very positive response when shown at a fan event during the following year.
The Kickstarter campaign is already 64% funded, with 27 days remaining for backers to pledge their support. Williamson seeks $10,000 to have boards made and programmed, cartridge shells cast, manuals and labels printed, reproduction Atari games boxes created, CDs produced and such. The Star Castle 2600 cartridge version will be handmade, serial numbered and be compatible with NTSC Atari 2600 systems. A CD version will also be available, containing everything required to play the game on your PC.
More information about the project and Kickstarter campaign can be found here.
Update: D. Scott Williamson has told Eurogamer that a PAL version in the works.
