Hi there not sure if my problem has already been stated but I've gone through the first three pages and haven't seen anything yet so I'm going to go ahead and shoot. I just installed PRO 6.60 B9 on this PSP 2000 and I'm not able to play the ISO's. I place it into the PSP/GAMES/ISO folder but when I go to run it I get an error saying that the data is corrupt. I've tried this with a couple ISO's now so I know it's not the ISO that's messed up.
So I've tried downgrading to a previous version of PRO but when I run the downgrader I get a message saying that the firmware is not supported. I'm at a complete loss, could somone please tell me what I'm doing wrong? Thanks.
