[Discussion] 60FPS patches for PSP games that run at 30FPS

North American Version (ULUS10505)
_C1 Force 60 FPS Mode
_L 0x21722E08 0x00000000

I tested this code and now the game runs at a smooth 60vps/60fps. I noticed the code filled an address with zeroes, is it possible to search memory for a similar value in other games?

Yes and No. There's not a direct answer to that, to be honest I'm not even able to answer that myself yet. The idea could work, the address or value thing might vary though, sometimes it may be more than just one (like Where's My Heart, it needs more than just one address and even then it has more tha 2 possible settings for FPS modes (30,60,90 or maybe more FPS).

Depends with what you mean with easy. I do it with Cheat Engine and by finding manualy every single time the offset the memory is mapped, it's quite a pain in the @$$ for me too. Also CWCheat cheat searching tool is soooooo slow and soooooo limited that I'm not using a real PSP to search my codes.

My question was for what your are searching to find possible addresses for the code your are looking for

I really want to set the FPS to 30\60 on Fate Unlimited Codes because it's running at 20FSP(internal)and it looks kinda slow(compared to the PS2 version)

Not really.
The first link is a preset syscall of PS2's Emotion Engine that either calls 60 or 50 Hz. With that you can set the video mode the game runs in, not it's internal framerate. PSP's hardware doesn't work that way at all. And the second is the speed which has little to nothing to do with it. Technicaly you could set PPSSPP to 120FPS on it's framelimmit and half the game's internal speed and this would result into 60FPS effectively but music and video would be in double speed. (This is what I did on PCSX2 and Kingdom Hearts 2 Final Mix+ before the real hack for 60FPS got out).
