This game install correctly into a win2000/winxp bottle. Applying the official
GP4 0.96 patch removes the warning 'please unload the debugger' (which is usually
related to the cd check mechanism failing), however the title still crashes wine
there-after. You might have more luck checking the WineHQ AppDB and seeing how things
are going there in relation to this title...see;
