Code:

_S UCUS-98700
_G Jeanne d'Arc
_C0 60 fps
_L 0xE0011420 0x0000921E
_L 0x2000921C 0x1000000E
_C0 60 fps [Disable]
_L 0x2000921C 0x1420000E

This completely skips the code that was patched previously, so it doesn't really matter if earlier 60fps patch was disabled before activating new one or not.

Thanks! The cheat code on the first post did not work for me, but this code does!

@LunaMoo Is it normal to not hold 60 FPS in Jeanne D'Arc, even with the 60 FPS cheat? FPS drops to 30-50 in a battle.

PPSSPP 1.12.3 windows. 12700K/3080Ti

EDIT: Nevermind! 60 FPS can be maintained by locking CPU to 333. Thanks fgeds and LunaMoo!

Could also be another timing issues, PPSSPP is far from being as slow as the real hardware and some games behave weirdly when programmed in a lazy, timing dependant manner. In both cases it could be patched via cwcheat, but in the first case it would not be an emulation bug.

Also there's a possibility just increasing emulated CPU clock would stop the FPS from dropping as it might simply be too slow to run at 60fps in that scene with default clocks.

Congrats on the promotion, i can certainly see why. You were again absolutely right, i changed cpu clock from "Auto" to 333MHz, and all drops are gone, it's rock stable everywhere now ( well, if i wildly, and i do mean wildly, rotate and move the map at the same time it drops to 50fps sometimes, but i think it is safe to conclude it's the clocks again) Thanks again!

Change the option in the picture.

Thanks! I tried 333 and max 1000. Still 40 FPS in my screenshot. Even with 60 FPS cheat, perhaps 60 FPS at all times is not possible due to the game itself?

EDIT: Nevermind, 333 works! Had to reload save state and it now locks to 60 FPS. Thanks!

I know this thread is really old but would it be pssible for you guys to make a 60fps patch for gundam battle umiverse(kidou senshi gundam battle universe)? I looked qt all of the cheats here and at anotherthread but i cant find one for it.

Hi, i know this thread is really old and long but i was wondering if there's a 60 FPS cheat for Prince of Persia : Rival Swords (ppsspp) i couldn't find one anywhere.

Bounty is still unclaimed if anyone wants to take a shot at it.

With the 3DS eShop closing and the PSP version being the only physical version of this game released, I really want to see this game the best it can be. It's never had a KAI port or anything to have better FPS, and I'm itching to replay this game.

This game has never been playable in 60FPS (not even the PC release supports 60FPS), so if anyone is able to find it and complete the code I'm more than happy to throw them some money or something.

Any Juiced 2 dinamic game speed code or 30FPS code? Please
