Is running emulators at 333mhz safe?
This isn’t necessarily overclocking the PSP since the CPU *IS* a 333mhz CPU. However it will be quite a drain on your battery, which is why the current PSP UMD games do not utilize this CPU speed. So far there have been NO reports of 333mhz harming the PSP, but this option is relatively new so still use at your own risk.
