I'm having a problem playing ISO games on my PSP. I have a phat PSP with CF v4.01 M33-2 and a 8GB memory card. I use UMD Dumper to BACKUP my STORE BOUGHT game to memory card. A few of the games work just fine. The others show up on my memory card but when I click "x" to play them it goes to a black screen. The only way I can get it out of the black screen is to pull the bat and put it back in. Any ideas would be great...

Try updating the firmware to 5.00 M33-3 and then trying to play them

If that doesnt work then your memory card could be fake

If you are 100% sure that your memory card isnt fake then you probably have a virus from your "store bought" games :P
