That depends on reverse engineering the custom chips that they use in those systems. The Amiga had custom chips, but had released the information on how they worked so Amiga emulators could be made. I doubt Sony or Microsoft would release the information. Just having a X86 CPU doesn't always mean the system can be emulated. For example I got BeOS for X86 and there is no emulator that can run it that I know of. My only hope of running BeOS apps is Haiku.
