It doesn't matter which loader I try, and I've tried them all. I end up with the same thing: a black screen from the moment I press 'X'. I've tried MultiMAN, the original PSJailbreak Backup Mangers v 1 and 2, Gaia manger, you name it. I've also tried numerous combinations of loading it from the internal HDD, from an external HDD, having no PS3 disc in the drive, having a disc in the drive, loading it straight from a manager, or being sent back to the XMB and loading it from 'app_home'.
And, just to be sure I didn't have a bad dump, I backed up another one of my games just to be safe; that also won't run. I've read somewhere that some payloads have backups disabled or something, although I got a payload that was sure to have them enabled, so I don't know whats wrong.
The game, The Orange Box, was on the compatibility list shown as working, which doesn't make much sense if I can't get this to work. If anyone has any experience with this,
How can I get backups to run correctly, and what do I need to do so?
