I revisited this stuff again ( i don't know why LOL) adding more cores and improving the experience using retroarch on original xbox a little bit. It's based on retroarch 1.7.7. It's a little old version but it have a lot of nice features. Here some other interesting features, but there's more... - Almost all retroarch common options
