I read in another forum these hacks are also working on real PSP. But i tested the gta vice city 60 fps on my PSP 2000, and it did nothing.

CWCheat can show cpu usage and fps counter on real psp, so i saw GTA VCS was not using 100%, and it kept running at 30 fps. Huh

Anyone found a 60 fps hack for mercury and mercury meltdown?

Actually I have a PSP 3000 and I test with it most of the codes that are posted here.

GTA games are special because they have slowdowns to a fixed 30 FPS with the codes enabled even on PPSSPP (you must increase the CPU speed to over 333mhz to fix this), so they only run at 60 or 30 FPS and not at intermediate FPS like with most games.

It's safe to say that if a game has a 20/30 FPS cap and you try to play it at 60 FPS on a real PSP, it won't be able to maintain this higher framerate with stability, except in some rare cases where "light" games were still capped by the developers (like Sonic Rivals) and run OK at 60 FPS.

However, I can confirm that most of the games that are capped at 20 FPS can be run at 30 FPS on a real PSP without big speed problems, a few examples I remember: Metal gear series, Star Wars games, GUN Showdown, the Simpsons game, Marvel Ultimate Alliance (I only managed to make this game run at 60 FPS and not at 30 FPS, which a real PSP can't maintain, yet it runs a lot better using the cheat).

And about Mercury games...

Archer Maclean's Mercury [EUR], ULES00011.ini
_S ULES-00011
_G Archer Maclean's Mercury [EUR]
_C0 60 FPS
_L 0x20058CCC 0x00000000
_C0 30 FPS [Default]
_L 0x20058CCC 0x1640000A
*Cheat Status: ??
I made some quick comparisons and the game seems to run OK, but as you are the one with experience with them, please report if you have any problem related to the code.

If you don't have the EUR release of the game, you can try the tutorial posted by LunaMoo about using the PPSSPP disassembly to unlock the games, as this is how I found this code. The same method should work with the second game too if they are very similar.

As an additional option, you can upload for me savestates with the game running on actual gameplay and using a "recent" PPSSPP version with the PSP model option as PSP1000, then I can port the codes to other game releases or to the second game.

Thank you very much!.

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 Smile)

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?.
