Xbox Emulator needed (for legal purposes)

Hey guys my xbox is broken, and i'd like to play Manhunt on my PC (the xbox version). I have it on DVD, but I can't find any xbox emulators that aren't crap. Help plz!!!

I wonder why there aren't any compatibility layers/virtual machines/Windows NT subsystems/etc. yet, Xbox is basically a tweaked PC with a custom static OS based on a subset of Windows NT.
