The emulator known as XQEMU is being developed and worked on as we speak. XQEMU is an open source, cross-platform emulator for the original Xbox (and Sega Chihiro). It is currently in very early stages of development. XQEMU is built on-top of QEMU.
It's far from playable, this is on these specs.

All videos are sped up a TONNE... some as far as x8 the original pace!
However this is the furthest XBOX emulation has come thus far... so welcome to XBOX emulation!
Dead or Alive 3

It's finally happening but god it needs some resources O.O
I'll finally maybe be able to play Kingdom Under Fire The Crusaders without the game crashing? I've already tried it on 3 original xbox systems. The sequel works, but sadly not the original, I think I need a version 1.6 xbox.
they should really only be working on like 3 games, metal wolf chaos, KuF The crusaders, and Jet Set Radio, I don't think those are available on any other platform, might be a few other exclusives to work on as well
