I sifted through about 50 pages of this forum and couldn't find anything on this. I have absolutely no problem playing any and all backups of my xbox 360 games, but I get that "This original Xbox game cannot be played on this console...blah blah" error about 50% of the time if I try to play one my backed up xbox games. They are all in U/NTSC region and I have the latest update from Microsoft (April 2007) to play original xbox games. Also, my xbox 360 mod is the latest Xeno360 V2. Very weird stuff. Like I said, xbox 360 backup playing is no problem at all, but xbox backup playing is 50% at best. I am thinking there is perhaps a patching software or something similar to 360xtract that could check the image? Thanks for any advice in advance!
