Getting the game to run on XP is no problem anymore (or did you have vista in mind?) and the corruptions we are talking about here will not be gone if you boot the same machine into Win98 (are there any drivers for the 8800 for Win9x systems anyway?). So this wouldn't do any good.
However, I thought about buying a Voodoo1 Addon card for PCI slots on ebay. Since my TFT has DVI and Vga connectors, I'd need no loop cable and this should work at the side of my main video card that has only DVI. But this is no elegant solution at all, because it is additional hardware, it blocks one pci slot (I only have two of those precious old things), not everyone has a monitor that has two input connectors and there will not be an endless supply of old PCI accelerators.
