I've also heard Codemasters European games have had issues running on NTSC/US-Canada systems too. I don't have much interest in those yet so I don't definitively know off hand. I am including a text file (zip'ed) I believe I got off Gamefaqs a while ago which does cover all overseas issues/compatibilities though.
