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

RE: [Discussion] 60FPS patches for PSP games that run at 30FPS
i've tested the PSP2 code and it just seems kind of "off" so for now i'm staying away from it until i've built experience to try and figure out "why" it's going funny.

but i was working on Rengoku II myself to some degree. here's all that i've got so far (double speed at the moment, as you found):
_C0 Rengoku Framerate Code On
_L 0x20083FF0 0x0084202A
_C0 Rengoku Framerate Code Off
_L 0x20083FF0 0x0085202A
_C0 Rengoku MS "60"
_L 0x202B15E8 0x00000001
_C0 Rengoku MS Uncap
_L 0x202B15E8 0x00000000
_C0 Rengoku MS 30
_L 0x202B15E8 0x00000002
_C0 Rengoku MS 20
_L 0x202B15E8 0x00000003
and incase you want the instruction address and values for the framerate code on it's own (for purposes as mentioned later in post):
08883FF0 slt a0,a0,a1 - 0085202A
08883FF0 slt a0,a0,a0 - 0084202A

the MS codes are number manipulation that would require refresh rate (the 60fps and Unlocked ones don't go at 60 in PPSSPP but do on vita) and the framerate codes are code manipulation (On being 60fps, Off being 30fps). is there any good links to a tutorial on finding the game speed code in a game though? if i can start trying to figure that out there might be some hope.

I've also been trying to plug away at simple series 2500 vol 13: the akuma hunters but i can't find it's limiter even (no 60-30 switching at all afaik, following the path of SceDisplayWaitVblankStartCB/Start yields no results thus far). any ideas? i can send a decent save for it (played it so much back in the day on my PSP that i'm nearer to the end of the main levels) if required for research too.

P.S. testing with some stuff on the vita with adrenaline and TempAR has come out that the code manipulation works directly with the in-memory addresses instead of CWCheat codes so rengoku II does go 60fps double speed on vita hardware too when you plug 0084202A at 08883FF0.

take that information and you might be able to really get some form of 60fps action going there too (Onechanbara special's 60fps code works a treat for example when adapted easily)
