Interesting. I’ve not had this issue before, but I very rarely have more than 3 stars so I can’t tell you if this is a problem with the port itself or your copy is messed up somehow. Maybe try reinstalling the game? I do remember that one mission would almost always crash for me, so I had to find a way to cheese it in order to complete it as opposed to doing it the normal way, but I don’t remember which one it was.
I don’t believe the sharing of games is allowed here (piracy), plus the project was nuked because of copyright. Otherwise I’d share mine.
However there do exist copies of the port floating around on the internet that might work…
