Click the link below and read the article. Also, scroll down and look at the screenshots - that should tell you whether that's the Star Wars "Arcade Game" which you seek (there have been several SW arcade machines over the years).
The author mentions the bonus disk being included with the GameCube version of RSIII - I'm not sure if it was packaged with the PC version. As pointed out in the linked article, for PC play, the MAME (Multiple Arcade Machine Emulator) software is still the way to go, but you've got to track down the ROM file for that game (possession of which is, of course, illegal).
Unfortunately, neither RSII nor RSIII had a PC version. :(
