Lyman Sheats programmed the video mode for GnR, it was subsequently recycled in Sega's 1997 'The Star Wars Trilogy Special Edition' (with different art) and in Stern's 1999 'Harley-Davidson� (1st Edition)'. Prototype software is missing the video mode. It is replaced by the following DMD text: "Under construction 5 million awarded". Many quotes and sounds are missing in the prototype software but no significant mistakes or problems seem to exist in it. According to Brian Schmidt, the GnR song Ain't Going Down can be heard only on this pinball machine. In an online interview, designer John Borg stated some games in the production run had head phone jacks, located on the cabinet front. An example of this is pictured in this listing. We previously listed the Manufacture Date as July, 1994. This game was produced from June-20-1994 to Aug-19-1994.
