Kurohyou 2: Ryu ga Gotoku Ashura Hen,enemies running too fast

[daniel229]

in chapter 5,the enemies running too fast and catch me everytime, so I can't get to the destination,setting whatever I set(software rendering,software transform read framebuffer to memory and so on),it won't help.Testing builds between 0.9.8-90~0.8.1

In JPCSP,it works with software rendering,or disable saving GE screen to texture instead of memory with OpenGL rendering.

savedata

with savedata,load the auto save,and you must fight a battle.

Is it possible to reach this area in the demo?

Hmm. I wonder if it's timing based on the GE or something.

demo does not contain chapter 5,but it can load the savestate,just missing some texture,you can debug it.

Thanks for that code,It works.

[unknownbrackets]

That's interesting. So that implies whatever is supposed to put data there is not working properly.

One of those looks like it's 1056.0f, the other possibly 0.00807189941f if it's a float. What happens to the speed if you make the 0x44840000 one 0x42D20000 (105.0f) or 0x457D8000 (4056.0f)?

[daniel229]

change to 0x42D20000 and 0x457D8000,the speed is a lot fast.

Does this happen with jit disabled (disabled before loading that area)?

-[Unknown]

[daniel229]

Disable jit does not help the game.

[unknownbrackets]

Does this still happen? I suppose it probably does, just wondering if #2921 might've been related. Pretty sure that happened with or without jit.

-[Unknown]

[daniel229]

Still happen.

[daniel229]

Change CPU clock to 25 helps the issue.

[daniel229]

ForceMaxEmulatedFPS = 20 also helps it.

Cars is penetrating through buildings tried both ogl and vk backend.

software rendering is correct

Anyone with chapter 5 save state I want to test it?

[ghost]

This is a Graphics Emulation problem.

[unknownbrackets]

Yeah, that's #9576 - unrelated issue, except that it's the same game. Well, probably unrelated - I guess there's some slight chance this behavior is affected by depth too.

Enemy is not running too fast using the ppsspp latest git build.

Also added this game id to ForceMax60FPS compatibility to slightly improve performance.

This issue can be closed now because I cannot reproduce @daniel229 issue also the reporter is not active anymore.

[unknownbrackets]

Okay, going to close it hoping it's fixed. Will be happy to hear from @daniel229 if it isn't (or if it is.)

I wonder if it's a timing issue we've improved.

This clip is from Kurohyou 1, the issue is in 2. The issue never existed in 1.
