patch=1,EE,001472ac,word,3c0243d6

With this widescreen code, the game plot is no longer stuck, but there will be missing graphics, can you help me fix it?

patch=1,EE,0019824c,word,3c023f2b try different values for second patch which seems to be zoom, or fov.

3c02 is real code.
3f2b is float 0.667969

Try to find good code that zoom enough, but not freeze game. Maybe:

3f3e

or

3f19

The value of 3f19 fixed it, the game no longer freezes, and the missing graphics are also fixed, thank you very much

Can you help me list all the hexadecimal values of the last two digits of 3f? I want to try more and find a perfect code.

Is just float, paste it to that site in single hex. Add 0000 at the end. For example 3f2b0000

 

[nifengyuexia]

Can someone solve such a problem, I tried multiple ways and nothing worked.
apiRequest (0.1)
local emuObj = getEmuObject ()
emuObj.SetGsTitleFix ("forceSimpleFetch", "reserved", {texMode = 2})
Can be solved, but the quality of the image is degraded, I wonder if there will be other repair methods

 

[kozarovv]

Check that make any difference:
--gs-kernel-cl-up="up2x2simple"

iis Cli

There is no comparison at all, this effect is too bad. But emuObj.SetGsTitleFix works better, with some slight jitter

This is upscaling issue for sure, so try some different options. I remember there was similar issue in VP2, i fixed it by that:

--gs-uprender=2x2
--gs-upscale=Point
--gs-kernel-cl-up="up2x2simple"

All of them are required.

Possible Steambot Chronicles (US SLUS_213.44 only) speedhack. Remove extensive postproccesing. Can have some minor visual effect. But speed up should be HUGE.

apiRequest (0.1)
-- postprocessing removal. Speedhack
eeInsnReplace(0x10fdd8, 0x0c042888, 0x00000000)
eeInsnReplace(0x10fea4, 0x0c04adf4, 0x00000000)

Edit, i see that wiki list also some graphical issues, to help i need picture of them. :/
Edit2: Issues were probably because of blur. I removed it. Game is now sharp, and look stunning.

Speedhack didn't take effect, and the graphics problems were serious, and the character strokes also had colored interference.

 

[kozarovv]

I think that speed is really good. Wiki list Massive performance and graphical issues.
Geometry, and graphical issues looks like standard clamping issues.

 

[kozarovv]

Fast fix, i reproducted the same issue on PCSX2, is clamping issue on VU.

So CLI:

--fpu-no-clamping=0
--fpu-clamp-results=1
--vu0-no-clamping=0
--vu0-clamp-results=1
--vu1-no-clamping=0
--vu1-clamp-results=1
--cop2-no-clamping=0
--cop2-clamp-results=1

LUA

apiRequest (0.1)
-- postprocessing removal. Speedhack
eeInsnReplace(0x10fdd8, 0x0c042888, 0x00000000)
eeInsnReplace(0x10fea4, 0x0c04adf4, 0x00000000)

That should fix whole issues.

Without configuration, the speed is the same

Ah, ok. I wouldn't know it run at that speed, i probably wouldn't try to fix it since start.
Anyway config should now make game playable, or at least with minor issues.

 

[kozarovv]

Actually is safe to use that CLI, to speed up little bit.

--fpu-no-clamping=0
--fpu-clamp-results=1
--vu0-no-clamping=0
--vu0-clamp-results=1
--vu1-no-clamping=0
--vu1-clamp-results=1
--cop2-no-clamping=0
--cop2-clamp-results=1
--vu0-opt-flags=1
--vu1-opt-flags=1
--cop2-opt-flags=1
--vu0-const-prop=0
--vu1-const-prop=0
--vu1-jr-cache-policy=newprog
--vu1-jalr-cache-policy=newprog
--vu0-jr-cache-policy=newprog
--vu0-jalr-cache-policy=newprog

Plus old lua.

Sometimes the audio stuttering problem will cause the illusion that the speed is reduced. If most of the game audio is repaired, the speed will increase.

Without any help, the graphics have not changed, the speed is still the same as when there is no configuration

Do not use it for games with normal speed. I have tested several games with normal speed, but it will become slow after using this command

If clamping on VU not help, then only full clamping can maybe help. Not really sure is worth to try. Is not first time when VU on that emu is pain in the ass Thanks for testing anyway.
