My PSP Slim & Lite is too slow.
The problem may be to to the fact that the CPU speed has been reduced. It often happens when using custom firmware.
You must set the CPU speed to 333.
- To acces the CPU setting, turn on the PSP holding the right trigger button ...
- Go to CPU speed
- Then on UMD/ISO speed and press the "x" button several times to obtain 333
