I am pretty sure that NFS Pro Street has a 60 FPS code (these games are using the same engine) but I don't have it, so I can't add it here.

I don't know for sure about NFS Shift (the last NFS game for PSP) but if EA used the same engine for the other 5 games, then this one probably is using it too

I said before that I have found a "perfect" 60 FPS cheat for Warriors Orochi 2, the problem is that the addresses are located around 07XXXXXX within PSP ram, not the 08800000 where game memory/CW cheats starts.

I can only activate it with cheat engine because of this. I tried to access that memory area with memory view and disassembly within PPSSPP but then I only see "??", not hex values. So sad...

Here's how Shift looks like



That's sceDisplayWaitVBlankCB. Nop'ing stuff makes the game run in x4 speed or just doesn't do anything at all.
Settings a breakpoint on sceDisplayWaitVBlankStart and sceKernelWakeupThread doesn't do anything.
