handsourcedyko,
the xbox is basically a broken down pc. Yes it runs linux. but it does not run windows. there was a port of windows ce done fo rit, but it is not fully functioning. it was more of a proof of concept thing.
The xbox does not launch EXE files, it launches xbe files. That is why there are teams at the xbox-scene that were or are dedicated to porting things to the Xbox, becaues the Xbox does not run windows games.
Of course you can use wine under linux, but with the limited capability to doing that, and sometimes wine won't run the games either.
The only linux that runs properly under Xbox is XDSL . all other ones have a hard time running and are slow becuase of the original Xbox's limited resources.
