I have the same problem in 2 psp's I upgraded to 3.03oe-c. Problem is the joystick gets stuck when it can be controlled up or down. For ex. playing NBA07 players keep moving even when you don't touch joystick or direction buttons but when I play diner dash (which don't use joystick or d-pad) everything is fine. Has anyone heard of this problem? I can only think it's because of the firmware because it hadn't happened before I upgraded and I was running a 1.5fw with devhook and that never happened. It can't be bad isos either because I used to play the NBA07 with no problem when running devhook. Any suggestions? Please help! Thanks.
