Auto adjust emulated FPS

[GuilhermeGS2]

The results of my test:

As Soul Calibur: Broken Destiny uses too little the CPU of PSP, only very low CPU clock values affects the FPS, with ~60MHz I still got 60 FPS even on PC, below 60MHz the FPS is affected. I found a confortable value that keeps the emulation speed between 95-100% and the FPS between 30-45 on my phone, I'm using 45MHz.

Change CPU clock doesn't work correctly for games thar have 30 and 60 FPS cap depending on clock speed, like Midnight Club 3, if you try to get a framerate between 30 and 60 with a clock higher than 222 and lower than 333, the game simple will run at 60 FPS and will suddenly drop to 30 when can't keep 60. It works if you try to run below 30 FPS, on MC3 you still will get 30 FPS untill ~160MHz, below this the FPS will be affected. It's usefull for Android, most phones can't even reach 30 FPS in this game, it's a CPU intensive. Anyway racing games are more playable above 30 FPS, it's more valid for non-racing games "playable" below 30 FPS.

As I can confirm on my test too, a feature that auto change the internal CPU clock woudn't work on PPSSPP, because the manual clock changes only affects the game after a reload the game or load a saved state, in Dolphin the manual clock change works realtime while the game is running. I don't know if it's a PSP limitation or a emulator limitation, but I doubt someone will want to work on this, so this thered is irrelevant.
