The weirdest thing happeneded today. I installed DEVHOOK and HEN for a long time and never had any problems before. I haven't played my PSP ever since X'mas, and I tried it today. I loaded DEVHOOK and make my FM to 1.5. It just stopped loading my ISO games. Each time I try to load my ISO games, it kept saying that I need to update my system software. Any great guy can help me, please!!!
