Change CPU Clock make PPSSPP run faster, can jpcsp do that? I'd want run jpcsp faster.

RE: Could JPCSP Change CPU Clock
If you're speaking about MIPS CPU. I believe JPCSP and PPSSPP don't work the same. I think PPSSPP emulates cycle count, so it's probably limiting some events or PSP thread execution according to the cycle count. If your machine is fast enough to have some long idle thread execution with a lower MIPS CPU clock (222 Mhz), so growing that MIPS CPU clock will allow shorter idle thread execution and more events or longer PSP thread execution, giving you the feeling ppsspp is running faster whereas it was restrained. I think JPCSP is running as fast as it can.

RE: Could JPCSP Change CPU Clock
There's one more aspect to it. If you lower the CPU clocks/second artificially, some games start frameskipping internally when they can't keep up, which can "improve" gameplay performance (although wrecking the framerate) on very weak machines.

This can cause strange issues in some games though so it's best viewed as an ugly performance hack.
