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

I am not sure if this cheat works, please test it and tell us if it worked for you. If it doesn't work, you can upload a SAVESTATE for me of your NPJH-50045 game with the PSP model option as PSP1000 with PPSSPP and I will fix it.
Check it on MGS cheats original post

Yeah, I have only managed to get 60 FPS at double speed with Ratchet & Clank Size Matters, the same for Secret Agent Clank and Jak and Daxter The Lost Frontier (they all use the same engine AFAIK), and after more tests I got double speed with Daxter too (I think it uses an engine similar to the others, maybe the first version).

This is so sad, if someone finds a way to fix at least one of those games, it would be easy to unlock the others.

More updates:
- I unlocked YS Seven with the "easy" method and used a speed modifier to adjust the gamespeed, but some things are still running at double speed (like game time and menus).
Using a different approach, which is adjusting how many frames get rendered, I can speed up the game speed perfectly, but can not make it slower as it uses an 1 (int) as the original value, and a 0 stops the game.

- Fate/Extra can be unlocked with the "easy" method, but runs at double speed. I have to search for a gamespeed modifier.

- I've sort of confirmed that FF Type 0/Reishiki uses an updated version of the FF Crisis Core engine. Using the 60 FPS hack for Type 0 posted by LunaMoo as a base, I finally made some progress with Crisis Core: can be run at double speed and porting other values may change the game speed. I tested a gamespeed cheat posted by VIRGIN KLM here, but I could not make it work. I'll keep trying...
