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

I have Archer Maclean's Mercury [EUR] and it runs perfect. Animations in menus seem to have just 30 fps so they move at 2x. But the gameplay itself runs at normal speed with no slowdows, on PSP and PPSSPP.

It is a shame the programmers locked most games to 30 fps, my PSP is runing Archer Maclean's Mercury at 60fps with default cpu speed 222 Mhz.

Can you post the link to LunaMoo's tutorial?

If i upload savestates, do I have to look for 60 fps and 30 fps scenes?. Mercury meltdown does not have any 60 fps part, all menus and game are always at 30.

I can upload savestates from Crazy Taxy Fare Wars, Mercury Meltdown, Snoopy vs the red baron (this one would look amazing at 60 FPS), The lego ones (they NEED 60 fps )

Would it be possible to disable that hardware filter many games use by default?. All PSP Lego games use it, or Flow, you can see dots and lines all over the screen in the attached image.

In pspsdk the function that activates this ugly filter is: sceGuEnable(GU_DITHER), Would it be possible to look at disassembly in a pspsdk sample with that function, and then look at the same code in another game?.

Yeah, I have always hated that ugly dithering/16 bit like effect in PSP games (especially the old ones), fortunately I can't see it while we play the games with PPSSPP (it's not emulated). It is a REALLY GOOD idea the use of pspsdk and some disassembly of samples to binary patch/disable the effect on retail games. I have never tried to code a PSP homebrew but I will try your idea.

About the savestates, doesn't matter at what framerate the game is running when you save them, but they MUST be from ingame/actual gameplay, not menus.

*Cheat Status: No issues.
*Game compatibility: Crazy Taxi Fare Wars has serious compatibility problems (not related to the cheat) with PPSSPP right now. It includes Crazy Taxi 1 and 2, but they are NOT running the same engine, they are individual games within this Fare Wars "collection" and each game has its own BIN file.

- Crazy Taxi 1 is unplayable as it freezes at most loading screens, and if you manage to get ingame, everything seems to be ok but when the race starts all the game graphics disappear.
- Crazy Taxi 2 doesn't have the graphic disappear problem but still has random crashes, especially at loading screens.

*How to use these cheats in a PSP.
I tried to test the codes on a REAL PSP and for some reason CW CHEAT freezes the PSP if you try to open the plugin menu after booting the game, so you have 2 options:

- Mills got an idea and said that if you set the 60 FPS codes to _C1 in the cheat.db file, and set cwcheat to activate the cheats by default, both crazy taxi 1 and 2 will run perfect at 60 fps, and without the need to open the plugin menu in the PSP.
- Alternatively, you can use NitePR plugin (CW CHEAT alternative for PSP), you just need to convert the format of the codes using THIS PAGE and they will work. But as NitePR doesn't have conditional codes(?), enable the FPS cheat you want ONLY while playing the specific game for it or the game may freeze. I recommend Mill's idea, it's easier.
