Thanks, very informative.

I feel like an idiot now.

Part of the problem is almost any popular Xbox game can be found on PC or Playstation 2. GameCube has a TON of exclusive games, there's no Zelda or Mario Kart available on the other consoles for example.

From the little I remember about the original Xbox I thought it was a Celeron CPU with Nvidia GPU running a Win2K-based cut down kernel? I would have thought that would be very easy to emulate??

Actually, the CPU's a 733MHz PIII according to Wikipedia, which is even easier to emulate. The problem is the OS, which isn't win2k at all, AFAIK, although we don't really know, and the fact the nobody could be bothered to actually cut the code.

Okay, partly wrong, there. There are some issues emulating the hardware. But given how crazy intel is about backwards compatability, the PIII itself might not be too hard...

I have no idea. Probably, nobody could be arsed to put in the work on it.
