Well it looks same like in Superman!

Code:

--gs-vert-precision=8

did you try?

yes, and sadly it did not fix. I also tested without the widescreen patch and without freeze fix.

also tried:

vu clamping combinations
vif1-instant-xfer=0
vu-const-prop
cop2-const-prop
gs-vert-precision=16
gs-flush-ad-xyz=always
assert-path1-ad=0

Trying different emus also didn't help. I'm currently sticking with Jakx v2 for all the extra options.

I'm starting to get scared of @Coro. Sorry!

It's curious, @Stayhye; Kya suffers from slowdowns due to the equivalent of 'INTC Spin Detection' in pcsx2 but ps4 emu not available disabled this. It probably shares issues with GTA Liberty City Stories and Vice City Stories.

GTA LCS and VCS were both fix easily with h2l commands. Those commands have no effect on kya

Code:

--gs-kernel-cl="h2lpool"
--gs-kernel-cl-up="h2lpool2x2"

Devil may cry 3 SE (SLUS-21361 and SLES-54186, and maybe also the regular editions) on PS4 has the famous mission 18 bug where you'll be unable to progress in the game (You won't be able to fight the boss/monsters in the crystal colours light blue, orange and purple), i don't why the game is still listed as playable it's clearly not, can anyone help ?

Test that game long time before! Well you can try for PAL

Code:

--Open All Levels
eeObj.WriteMem32(0x204A2400,0x00000000)

For NTSC

Code:

--Open All Levels
eeObj.WriteMem32(0x204A1480,0x00000000)

why can't you fight the boss? does the game freeze? what exactly happens there?

*edit - the game needs EE Round Mode to Nearest... unsure how to do that on PS4

Yeah i saw that too in the PCSX2 Wiki, i thought that maybe someone had an idea on how to set the EE Round Mode to "Nearest" on a PS4.

probably something like "--fpu-clamp-range" or similar fpu accuracy command

mrjaredbeta · Aug 10, 2023

I asked and Kozarovv delivered yet again:

Code:

-- SLUS-21361
apiRequest(1.0)
local eeObj = getEEObject()
eeObj.AddHook(0x20A9F0, 0xF8400030, function()
    local sp  = eeObj.GetGpr(29)
    local val = eeObj.ReadMemFloat(sp + 0x84)
    eeObj.WriteMemFloat(sp + 0x84, val - 0.1)
end)

Port of PS3's hook to adjust floats. This hook was made before accuracy commands were implemented in the emulator. This should be a lot faster anyways.

Experimental, may or may not fix the issue. Needs testing!

joker11 · Aug 10, 2023

What's also interesting about this bug is that it was also happening on the backwards compatible PS3 lunch model (The one that had the PS2 chips inside) but was later fixed by PS3 firmware version 2.01.

I think this will be needed after apiRequest for GetGpr to work
