Quoted from McSquid:I recently took a recording of this alternate music from my machine for a friend. I found this thread and saw requests for the recording so I uploaded it for you. After running different roms on Visual pinball I found that the U1 prototype is the only one with this song. (That I found) It also does not have any female callout voices (which is what made me originally notice something was odd with my sound)
I've never resurrected a thread this old, but seeing as though I requested a recording of the prototype music 10 years ago and then saw that I was 6 YEARS late to seeing someone had actually posted it, I just had to respond. Truly incredible and honestly an awesome alternate main theme, I love finding pinball easter eggs like this! Would be awesome if there was a rom hack with both main themes as options, but probably more trouble than someone would be willing to go through to make it happen.
As far as I know, the only three System 11 games with unused complete music tracks are Swords of Fury, Police Force, and now Rollergames.
Oddly, I went down this rabbit hole again today (after a whole decade) because this news clip surfaced in my feed and strangely enough - you can hear the prototype music toward the beginning of this video while Steve Kordek is showing the reporter the Williams showroom. I was like... that sounds like Rollergames, except not? That lead me back here, so belated thanks for sharing!
