Someone like Uknown though could find the address that calculates how busy the CPU is and kill that or make it return that it's not busy so the FPS cap will go to 60FPS but I can't find that myself with the knowledge I have.

From the demo, it's calling sceDisplayWaitVblankStartCB 3 times per frame. What fps does it run on a PSP (cwcheat can tell you, just go to options)?

Anyway, this game is spending a seemingly ridiculous amount of time in beziers. Also, this seems like a timing problem.

08853C78 0E29E986 jal zz_sceDisplayWaitVblankStartCB

08853C8C 1440FFF3 bne zero, v0, pos_08853C5C

(from the demo, might not be the same in the game.)

Change those to nops, for now, and you'll get 30fps.

08853C5C 0E29E986 jal zz_sceDisplayWaitVblankStartCB

Change this also to force 60 fps at least in cutscenes. It seems to cause a fast forward effect.

08853C00 0E29E986 jal zz_sceDisplayWaitVblankStartCB

Change this too to get 60 fps fast forward elsewhere.
