So if an emulator doesn't "get it right" 100%, it's not an emulator? :p
Microsoft got farther than anyone else. The emulation they use in the 360s is the fastest and most accurate thing available to anyone. Fwiw, more games "work" than not (that is to say they're "compatible" in MS' terms), at least the vast majority of NTSC-U games are, though emulation isn't perfect in many games (welcome to the world of emulation Microsoft!). That's not to say that any of the problems were outright technically impossible to fix either.
It's still almost a decade ahead of any other efforts to emulate the original XBOX. So yeah, decent XBOX emulation already is here. I rest my case. Now about excellent XBOX emulation...
