Heck with Vista, that demo doesn't even work on XP due to DEP issues.
Depending on which version of Blitz3D you have, the demo source code shipped with the Idigicon (physical product) version. You can probably just compile it with the latest Blitz3D and get one that works on both Vista and XP.And yes it's still a pretty cool game. It has just the level of golf game complexity that I care for.
