I just purchased devil may cry 4 (awesome game btw) and I have just downloaded a pal copy to usr as a backup and I have a couple of Q's: 1. Even though devil may cry 4 is region free, will there be any video problems/problems in general playing on a ntsc-u 360? 2. If I save the backup PAL copy, can I play the NTSC-U copy from where I left off? Thanks!
