Wine, which can be run on a unix environment such as Linux, is such an emulator Strictly speaking, WinE isn't an emu. WinE only runs on Linux machines running on Intel architecture, and doesn't emulate the machine -- it runs them native on the processor. I'm not sure how it deals with DirectX though. Personal use is what I was thinking. Actually, I was thinking that if such a program could be built, it would sell in the marketplace quite well as plenty of people would find it entertaining to set up scenes with their favourite millenium folk battling critters from Final Fantasy as fan art and so on, even if the meshes are lower poly.
