Emulating PSP CPU overclock?

[bugmenot]

I think you're mistaking thing here, see PSP has CPU which is being emulated by jpcsp, this emulated cpu is just like the real PSP cpu has standard clockspeed of 222MHz (iirc) and can clock itself dynamically from 1 to 333MHz according to wikipedia, if you ever tried CFW you'll know that you can force PSP to clock itself to its max clockspeed which result in smoother gameplay for most games but at the expense of battery life.
