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.

I did not used LunaMoo's tutorial for these games as they were super easy to find their 60 FPS code.

Most of the PSP games I have tested have an address somewhere that sets the game FPS with only a single value (like a frameskip, where 60(FPS)=1(address value) , 30=2, 20=3 and so on), so this is the first thing I try with a game to unlock the FPS. I have a lot of these 60 fps codes, the problem is that the games are double speed and need some fixing and stuff to be played at normal speed (these can be combined with slowmotion/gamespeed codes that we can find on internet so they can be played at normal speed).

However, a few games do no need any extra code and this change unlock the FPS perfectly. This is the case for a couple of codes that I have posted here: NFS, Sonic Rivals, Project Diva.

@GamerzHell9137 Use cheat engine or similar to scan NFS Shift game memory while it is running (I recommend you to scan only the PSP RAM beyond 0x08800000, so use a range scan), with a exact search of "2" (when the game runs at 30 FPS, see above) and you will get a few hundreds/thousands of results, then just change the values you got in small groups to "1" (60 FPS), at some point you will see that the game is running at 60 FPS, identify the exact address and then you just port it to a CW Cheat address.

This may be a random method for this, but sometimes it is effective. I am not a pro like LunaMoo is (my respects to you and your contributions), I am just fascinated with this 60 FPS trend Tongue and I want to contribute a little on my own (I even posted a 60FPS cheat for MGS3 at the PCSX2 forum).
