That depends on reverse engineering the custom chips that they use in those systems.<p>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.<p>Just having a X86 CPU doesn&#x27;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.
