[solved]XBOX 360: WHY wasn't it x86?[NEW QUESTION]How hard would it be for MS to emulate/go BC with original Xbox games?

[Locura XD]

I think BC was not possible before because of DRM policies that very different to the XB360 and not a technical problem because there are some powerpc-x86 emulator, for example the Wii/Gamecube.
With all the resources they have, MS should be able to find a way that worked.
