IMO is just a jumped up PC, which going on hardware alone should be a peice of piss to emulate especially with my computer, 1.4 ghz twice as fast as X-Box and (Maybe more importantly) NVidia GeForce3 the same GFX chip.
Who knows, X-Box may actually be a PC that boots direct from DVD/CD's for all we know (Highly likely if you ask me) I'm sure developers will release identical games (Just using Windows) for GeForce3 equiped PC's as they do for the Crap-Box.
BTW there are a couple of emulators for the Saturn my friend, links can be provided if you wish
PS You'll need some Saturn CD's though
