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

[solitarius]

This is for Twisted Metal UCUS-98601
If you set that 1E(30 in decimal) to anything higher then 3C(60) the game runs in 60 fps with correct speed but the camera is locked.
If you unlock the fps to 60 and force that 2 in the image to 1 with the following assembly 089A99D0 li a0,0x1 then enemies, animations are correct speed but player is doubled. Maybe Kabuto_Kun or someone else can take it further.

Regarding cutscenes in general, ussualy there are keyframes stored at 30fps, which you cannot unlock to 60. Example: in Halo 1 remaster, enemies are still animating at 30fps, despite the game running at 60, and this with Microsoft having the source code for the game,assets, etc... the same with other remasters which remained at 30 because animations where stored at that framerate.
