I backed up MVP 2005 using DVD Decrypter to make and burn and ISO, but the game plays SOOOOO slow locking up for seconds at a time. I did a search for using ISO Buster and other programs to rebuild it, but couldnt find the info I needed. Is there a patch to burn this game? I'm using a Duo 2 mod chip on a PS 7. All my other backups and originals play fine.
