Ok i have been making backups for my ps2 for a while now. i got that all figured out so now i'm going to mod my xbox in some form to play xbox backups. i have a friend that wants to backup up his games too but he doenst want to mod his xbox. i know i have to mod my xbox to make the backups but does he have to mod his xbox to play the backs. So the question is doesnt ur xbox have to be modded to play a backup game disc or just modded to make the backup?
