Emulator

If something is similar to PC it doesn't make it easy. You have an xbox1 that is basicaly PC and yet we don't have decent emulator for it.

That's because almost no one cares about xbox1 emulation, most good games were ported to PC at the time anyways.

Being close to a PC in structure does make things easier and faster. Early xbox1 emulators consisted in converting the xbox game files to the windows executable format on the go. You can't do that with a playstation

Even so, port of Halo on PC was catastrophic : too slow, much further slow than with xbox 1rst gen
