The key part there is that the original xbox is a Pentium III PC with, iirc some northbridge/southbridge shenanigans. And the PS4 uses a custom AMD x86-64 chip

An Xbox 360 is slightly more difficult as that is a PowerPC architecture (RISC vs. CISC of x86)
Same for the PS3 except you also have those incredibly weird "SPE" cores to try and emulate as well.
