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

[LunaMoo]

Cheats are just memory patches.

You can for example use them to modify game code that tells the game to reduce your hp when you're hit to never do it or do the dumb way of freezing HP variable stored in memory, but it doesn't matter if you care about HP or FPS or anything else, if you know MIPS, you could in theory reprogram the game into a different game, so small modifications are often very easy, althrough low level programming can be a bit tedious and time consuming.

Most PSP games were designed with 30 fps in mind and often are very hard to patch without many game breaking issues, however there are games where FPS was limited afterwards and those often don't have any problems when you remove it's internal frame skipping.

As for why - you have to remember that PSP is a handheld device with pretty small battery, that only got worse with time, it might not matter to you, but for most people running a game for 5 hours at 30 fps was much nicer than running it for 2.5hours at 60 fps especially when all the early PSP screens had ghosting and not much benefit of running in higher fps. Many games ran under 30 fps and also often didn't had to, but the difference in gameplay time vs smoothness on the real hardware was making the time more important factor.

Guys, I'm trying to follow the tutorial but my debug console doesn't show the mem thing, what gives?

Would anyone be able to create a slowmotion code to complete the 60FPS code for Gurumin? I gave it a shot and wasn't able to find it.

This game has never been playable in 60FPS (not even the PC release supports 60FPS), so if anyone is able to find it and complete the code I'm more than happy to throw them some money or something.

This code dont work. Game still work on 40fps. Anyone know why?
I love this game and I would play this game on 60fps. Please help <3

This completely skips the code that was patched previously, so it doesn't really matter if earlier 60fps patch was disabled before activating new one or not.

Thanks! The cheat code on the first post did not work for me, but this code does!

Any have working 60 fps cheat code for TOCA/DTM RACE DRIVER 2. Previous code on this site for this game not working and game work on 40 fps. Anyone know how to play on 60fps?

I'm going to put a bounty on this. If someone adds a slow motion code to complete Gurumin's 60FPS code, I'll send them $50 via PayPal. No strings attached. With the 3DS eShop closing and the PSP version being the only physical version of this game released, I really want to see this game the best it can be. It's never had a KAI port or anything to have better FPS, and I'm itching to replay this game.

Anyone here could please give a guide on how to made a game speed modifier? I managed to get Fate Extra running at 60fps but as expected, it runs at double speed. I've already tried the trick on searching what floating values switch when I change fps but freezing them does not work. I don't know any MIPS but I found values in the disassembly such as zz_scedisplaygetframespersec, zz_scedisplaysetframbuf, zz_scedisplaysetmod, zz_scedisplaywaitvblankstart, and zz_scedisplaywaitvblankstartcb. Could anyone give me on some advice with getting the game modifier code to run properly at 60fps?

the 60fps patch doesn't appear to work for Jeanne D'Arc on Android.

here is some other guy also not being able to apply the patch on android

Would be great if someone knowledgeable looked into it.

If it doesn't work, you're probably using wrong cheat, old one was ment to workaround bug causing weird fps. To run Jeanne D'Arc with 60 fps in any reasonably new PPSSPP version you need new patch.

I made one right after solving the game's timing issue and posted here, but the whole 60 fps list is poorly maintained and full of outdated and broken codes.

[fgeds]

Omg indeed. How could i not find it.. In fact the same question was posted like 5 comments before. Navigating on Android got the better of me, i'm sorry. And ye, your version works. Thanks!



Although i did a little testing, on fogged maps, ( forested ones, but not the tutorial starter map, it has no fog), with fog in play fps starts to fluctuate. Example: https://imgur.com/a/QEO81gV just by moving the cursor fps changes from 60 to 52 to 40 to 30. Choosing to show all possible moves, drops fps to 30 100% of the time on this map. And never on some other maps i tested. And in all cases uncapping fps, regardless of map or current fps, it accelerates to ~90fps.

This is (latest) PC version v1.12.3-1264 ( same behavior on Android)


By no means this is any sort of criticism! Looks like game issue.

For science, i started my main PPSSPP version, don't laugh, v1.2.2 ( hey it still works, and is full of save states), with the old Jeanne's patch too, it exhibits the same behavior when picking to show all possible moves and drops from 60fps to 30fps.

[LunaMoo]

If you could provide a save or savestate to reproduce it, preferably before triggering the problem with steps to cause it, I could check it out, but no promises, since I got promoted in my real life job I rarely look things up in PPSSPP. But there are others that could improve it that lurk around the forums as well.

My guesses would be game might be programmed to reduce FPS in specific conditions to conserve power, using additional frameskip to the one that was patched. Could also be another timing issues, PPSSPP is far from being as slow as the real hardware and some games behave weirdly when programmed in a lazy, timing dependant manner. In both cases it could be patched via cwcheat, but in the first case it would not be an emulation bug.

Also there's a possibility just increasing emulated CPU clock would stop the FPS from dropping as it might simply be too slow to run at 60fps in that scene with default clocks.

@LunaMoo Is it normal to not hold 60 FPS in Jeanne D'Arc, even with the 60 FPS cheat? FPS drops to 30-50 in a battle.

PPSSPP 1.12.3 windows. 12700K/3080Ti

EDIT: Nevermind! 60 FPS can be maintained by locking CPU to 333. Thanks fgeds and LunaMoo!
