It's not for the EUR version.

There's that address:

_L 0x2030C7E0

Setting the value to 0x00000000 it will cap gameplay to 30FPS. Setting it to 0x00000001 will cap the gameplay for some reason to 15FPS.
I guess I'm close to finding how to do it but I may need help for it.
I guess also setting it to 0x00000001 could be a nice cheat to make the game play easily on Android.
Gonna repeat the code on the game's section in case somebody wants to play it on Android and doesn't have a capable device.

nice discovery

Actually, I was just messing around, and I found that setting the value to ANYTHING other than 0x00000000 results in a 15 fps lock. not just 0x00000000. I could put 9x94628562 and it would still lock at 15.

also using software rendering locks the cap at 60, if that's useful.

Yeah that's because the address has a bahaviour to half the current cap of FPS. 0 leaves it as it is and any other halfs it. I need to find which address stores on what FPS the game will display, double them (120 FPS) and then half them with that code.

Thanks for your researches
Anyway, I own the EU version of Monster Hunter Freedom Unite, it means that the codes will be different, isn't it ?

Yes but 99% of the times it's simply an offset on the memory allocation.
Judging from the addresses I see online on the EUR and USA versions of the game, for example, on the Infinite Money cheat I see that USA version has an offset of +00000140 so on the EUR version the address you're looking for must be 0x2030C6A0, try it.

So I tested the following code :

Code:

_C1 15FPS Cap
_L 0x2030C6A0 0x00000001

And indeed, I can see a 15 FPS cap while the game is running...
But here is a question : Is it normal that when the intro video is displayed the game still run at 60 FPS ?

If the question means if I get that too then yes, if the question means if it's supposed to work that way, I don't think there will be somebody that could answer that question. I need to find the exact way the game changes video mode and I found only a clue so far.

OK, thanks for the informations
I hope you will find what you are searching, I can help you in testing and maybe more if you explain to me how to

[VIRGIN KLM]

Technicaly speaking, the base idea is that there is a Byte value changing each time the game swaps video mode. I know this means like 6.000.000 addresses worth of testing but it can get with some clever thinking narrowed down to near 200.

OK, I understand better now, thanks
I wish you a lot of bravery in your researches, and if I can help you, just notify me

Hi, I was directed here from another thread, and I've noticed that Initial D Street Stage is also capped at 30 fps, is there any way for it to be played at around 50-60 fps? Also, i?m playing it on pc instead of Android or ios. Sorry if this game was already addressed previously

[Maverick81PL]

Any fix for Monster Hunter 3rd HD Version to 60FPS?? And how apply this??

I can (attempt) to do this on games that have more than one video mode for the momment, like Kingdom Hearts Birth By Sleep, it is 30FPS on gameplay and 60FPS on menus. If a game doesn't do such thing it doesn't mean importantly that it's impossible, it just means that I'm not able to do it with my near to zero knowledge to do such thing.

I'm really brainstorming what the hell is this thing that instead of making the game 60FPS it's making it 15FPS with my code, people that know what I'm trying to do here could try to give me a help. You can't believe how many times I tried to do stuff and the only thing I succeed was crash the emulator.

Initial D has the exact same issue! 30\gameplay 60\menus. Thanks in advance for looking into it.
