Hi all, Ive been looking around to see if anyone has had this problem, and it seems some have. Basically, I was running devhook 0.46 on my downgraded 1.5, when I decided to look more into the custom firmware. I upgraded to 3.03 OE-C, and found that when I ran a few games, the game saves were corrupt. I could save a new game, and that would be fine, but using old game saves made from within devhook, seemed to always be corrupt. So, when I got home that night, I played around, and copied all savedata folder to my pc, ran a "format memory stick" from the XMB, and then copied the savedata back to PSP. Now, using old gamesaves seems to work. Has anyone else had problems with this here, and is the format method a viable way of sorting this problem? Cheers for your time, Jim.
