Star Wars AND Emulation? In the same thread? I've died and gone to heaven.
The Arcade Version was ported to Atari 2600, the 5200, the ColecoVision, Atari 400, and the Sinclair ZX Spectrum, as well as the Commodore 64, the Atari ST, and the Amiga.
The Emulator Strikes Back, a page hosted by EchoStation, has a complete list of Star Wars games ported to different systems. (http://www.echostation.com/esb/index_javascript.htm)
