Hello, First time posting here, and I'm having a bit of trouble playing PSX games in .ISO (or .CSO) format on 3.03OE-A. Every place I've read says to create an "ISO" folder in the root of your memstick, and just throw the ISO (or CSO) files in there. When I do this, and then go to the memstick section of the Game menu...it just says "Data is corrupted" and I cannot launch the game. I also read that you need to have a UMD game in the drive, which I do. I can take the same exact ISO file and convert it to an EBOOT.PBP and it plays fine (from the PSP\GAME\ directory). I've tried about 4 different game ISO's, and I always get this result when trying to use an ISO/CSO. What am I doing wrong, what do I have to do to run ISO/CSO files on 3.03OE-A? I know I've got to be missing a critical step, but I've been reading for hours and can't find anything about my problem. Any help is greatly appreciated, thanks in advance!
