There's one game I've yet to be able to replay. Diskworld 2. It has compatibility issues that no one seems to be able to solve. What I can understand of it is that the Dosbox(and similar programs) are unable to find the CD for that game for some odd reason. The only way to play it is to fish up an old computer running Win 95 or older. Running Diskworld one is peace of cake though.
This is a longshot but... maybe you can find an emulator to install and run windows 95 on your computer. then install the game. (I have a emulator that allows my mac to run everything back to windows 3.1! )
Virtual PC. But I think that only works on Vista.
Also, it's spelled Discworld, with a 'c'.
