Just wondering: do you think if would be possible to get soundtracks as additional downloads for the Pro Pinball games? I love this series, and I've always especially liked the soundtracks, but I've never seen them available anywhere. As one of the other pinball games on GOG (Pure Pinball Redux) has a downloadable soundtrack as an extra, I would be ecstatic to see this for the Pro Pinball games as well.

I second this.
The music was actually on the CD on the original version. You could play it through a CD player, but it was all on one track (as is the case with most games). It would be great to have this as a download, since it did come with the original. The music in Timeshock is incredible.

If it's like previous games here.
pptime.gog & pptime.inst is the CD & track data. It's mounted as an ISO in the DOSbox game directory *.conf file.
It's not the easy solution, but you can mount these as an Audio CD and play. There is details in another game/thread on it.
That said, the music is fairly rocking good, and I'd also like an easy to grab MP3 edition.
