I have a phat PSP. I updated to the prometheus things with 5.50(forget the exact number). It allowed to me to play newer games, but they'd often freeze, same with emulators. So I decided to update to 6.35 pro-B3. and it's no better. I've tried mutliple ISOs, ROMs, Eboots, emulators on 3 different memory sticks.

Anyone else have troubles like this?
