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

Rather than patching 60 fps i really want to patch 30 fps instead.
Some games run 60 fps natively, and that is too demanding to run on mid range devices, 30 fps will be a sweet spot.
I managed to cap 30 fps in some games by CPU clock, but it also drop the performance despite the 30 fps. Like your phone in low-battery mode.

I read this by LunaMoo about breaking down Vblank function related to games code but really couldn't get my around it.

Anyone with experience can give this a look ?

If a game runs natively at 60fps, you can easily force 30fps by changing the Frameskipping value to 1.
(My device isn't very strong, and suffers performance drops in 60fps games. This helps a ton.)
