The bios is not looking for a different xbe, as it is the same bios, and same setup as my own box. It is a freshly downloaded, unedited version of Unleash. It boots to a blank screen, and shows no audio or video.
Like I think I mentioned (or maybe not) Avalaunch also has problems. It freezes on boot, just like he said it did after he 'changed some stuff'. I was able to boot to an avalaunch boot disk, but never tried a UX disk.
He said he accessed the gamesave manager, and deleted some stuff he didn't recognize. He also I think went into E and deleted some random stuff. I figured a clean format/install would fix it, but still had the same problems. EvoX works though! So he's gonna have to stick with that. I'm curious if I format the entire HD, if it would still have problems, because it seems that way.
Thanks for the help everyone!
