I don't know without testing it...

Can you test and add configuration for this game?

--ee-ignore-segfault=RW is what should get rid of segfault, but even then game can crash. This is just error remover.

Edit: Nevermind, you have different error. No idea.

Thank you very much, maybe giving up is also a good choice. I will test other games!

My God, this should be the most serious graphics problem in the games I have tested

Kind of. But is more complicated.

Because of sync issues between EE-VU.

You should take a look at these two files:

Rayman 3

Rayman M:

In rayman 3, nopping these two addresses:
00101194 4846E800 cfc2 a2,VPU-STAT--
001011B4 4846E800 cfc2 a2,VPU-STAT--
The game will create an infinite loading screen loop and it will show this error in the register (PCSX2):
sceGsSyncPath: VU1 does not terminate

Here are games that require xgkick hack + value to use. Bold are ones that are most promising to be tested on ps4, titles that aren't bolded probably require a lot more patching. Remember to test titles with

Code:

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

Nope, different issue.

Possible fix for Castlevania: Curse of Darkness SLUS_211.68 only
I'm correcting some calculations on VU to get correct clipping. That should remove SPS. At least on PCSX2 it worked without changing clamping. Please test. Issue was massive gfx corruption since start, and after going into chamber. So is easy to check. FYI @sabin1981

Code:

apiRequest(0.1)

-- loi 255.0 to -255.0 to fix cliping calculation
emuMediaPatch(0xba2, 12 + 0x528, { 0x437f0000 }, { 0xc37f0000 })

The European, American and Japanese versions of this game have gfx problems, which are not as perfect as the European version on WIKI, which is misleading. I will apply the configuration you issued and test it.

This configuration has no effect。

I have KOF98 config, is different situation. Problem is that most of things like that will be game specific, and require specific patches. Here is KOF98 fix for that from official config.

Code:

apiRequest(2.0)

local gpr = require( "ee-gpr-alias" )
local eeObj = getEEObject()

            if (stat ~= 0) then                            -- if not, we need to fix           
                if (i > 1) then                            -- if this is any but the first entry
                    stat = eeObj.ReadMem64(pTbl-0x10)    -- fix by replacing the x, y with

                        stat = eeObj.ReadMem64(pTbl+0x10)

As you said, the situation of each game is different, even if it is the same game, the problems to be fixed in different versions are different. I have the official European version of the King of Fighters 98 configuration. Compared with what you have issued above, they are not the same. Thank you for your contribution to PS3 and PS4 simulation PS2, I know that you no longer have PS4, if there is a new game configuration to be tested, I can provide testing help

I stripped texture replacement, and shaders from config, that why they aren't the same.

Just wanted to point how that exact issue is resolved there. Original config will break game without shader/texture files. One i posted above should work fine on custom iso (with cli from original, and without uprender (set to none)).

I want to apply the above configuration to the Japanese version of the King of Fighters 98UM for testing. Can you transplant them for me? Because I mostly play the Japanese version in our area, I have some requests! SLPS_25783

Pm me SLPS_257.83 file. I will see they are differ much

Well, that function is different in JPN release. This can not work. But try.

Code:

apiRequest(2.0)

local gpr = require( "ee-gpr-alias" )
local eeObj = getEEObject()

-- Fix bug 10414 - large stretched polygons block view of player characters

local FixPointTable = function()
        
        local s6 = eeObj.GetGpr(gpr.s6)                    -- obj in question

        local numPts = eeObj.ReadMem32(p5Tbl+0x110)        -- num points in list
        local pTbl = 0x1D47840                            -- bg_point_buff (we need to scan this)
        for i = 1, numPts do
            local stat = eeObj.ReadMem32(pTbl + 0xc)    -- check 4th word, should be 0
            if (stat ~= 0) then                            -- if not, we need to fix

                end
