I would like to firstly say thank you to all that have helped me already, but I'm a little confused. I've made some backup copies of my games so I can take to school and not carry around all my UMDs. They have been dumped/backed up successfuly and I can play most on 3.03OE-C. There are some I can't get to work on 3.03OE-C so to see if they was bad isos I downgraded to 1.50 again and used devhook 0.46. I loaded up the games that would not work on 3.03OE-C and they work totally fine! How come they work fine on Devhook and struggle to load of 3.03OE-C? I don't really want to use Devhook on 1.50 because I love 3.03OE-C too much (I also feel safer). If you want the names of some of my backup games then I shall post them.
