with giant rats. The port was released in Japan on February 10, 1994, under the name Wolfenstein 3D: The Claw of Eisenfaust before being released in North America and Europe later that year. Using the source code of the SNES port, on a whim John Carmack later converted the game to run on the Atari Jaguar. Atari Corporation approved the conversion for publication and Carmack spent three weeks, assisted by Dave Taylor, improving the port's graphics and quality to what he later claimed was four times more detail than the DOS version. He also removed the changes that Nintendo had insisted on. However the game's code had to be slowed down to work properly on the console. Since its initial release, Wolfenstein 3D has been ported to numerous other platforms as well. In 1993, Alternate Worlds Technology licensed Wolfenstein 3D and converted it into a virtual reality arcade game. The 1994 Acorn Archimedes port was done in UK by programmer Eddie Edwards and published by Powerslave Software. By 1994, a port for the Sega Mega Drive was under development by Imagineer, who intended to release it by September, but it was cancelled due to technical problems. The 1994 Classic Mac OS version of the game had three releases: The First Encounter, a shareware release; The Second Encounter, with 30 exclusive levels; and The Third Encounter, with all 60 levels from the DOS version. An Atari Lynx version of the game was offered earlier by Atari for id, but work on the port was never started, save for a few images. A 3DO version was released in October 1995. The Apple IIGS port was started in Fall 1994 by Vitesse with Rebecca Heineman as the initial developer, with later graphics assistance by Ninjaforce Entertainment, but due to licensing problems with id it was not released until February 1998. An open source iOS port programmed by Carmack himself was released in 2009. An unofficial port for the Game Boy Color was made in 2016. An Android port titled Wolfenstein 3D Touch (later renamed ECWolf) was released and published by Beloko Games. Other releases include the Game Boy Advance (2002), Xbox Live Arcade, and PlayStation Network. These ports' sound, graphics, and levels sometimes differ from the original. Many of the ports include only the Apogee episodes, but the iOS port includes Spear of Destiny, and a 2007 Steam release for PC, macOS, and
