"--vu-xgkick-delay" accepts decimal values
"--vif1-instant-xfer" accepts values up to 60000+ in my testing

Is there any obvious difference between a high value and a low value?

Stayhye · Feb 9, 2021

I discovered this while tinkering with virtua fighter 2. No difference I could see in that game.

--vu-xgkick-delay=0.58 fixes Def Jam Vendetta's missing character models, and stage assets.

edit* 0.58 appears to stop the random crashing. Still testing, but everything is all good for now

This is just 0, or non 0. There should be no difference between 1, or 60000.

And that i don't know why even work. You are using float for command that expect integrer. You can't delay something by 0.58 cycle. So it is rounded to 1, or... 0. is ignored, and value 58 is used. In second case using 8 probably will be enough.

In my testing
0.50 broke Def Jam vedetta
0.54 all graphics started working but randomly crash
0.76 goes back to no models, graphics, etc
1,2,-->16 no change. no models, textures, etc
17 crash emu

kozarovv · Feb 10, 2021

Can you try just 58 then?
Edit: I just want to know that we really can use float value. Because that will be stupid on emu side. :P

--vif1-ignore-cmd-ints= accepts decimals too. 0.9 doesn't boot onimusha blade warriors, 1.0 does, 1.1 back to black screen

I'm sure it doesn't accept floats, that way just create undefinied behavior. This work similar to --vif1-instant-xfer
But in --vif1-instant-xfer case default value is enabled, so check in code is 0 or not. In --vif1-ignore-cmd-ints= default value is 0 so compiler made check more complicated, and compare value to 1. Still not sure why it even accept 1.0 as correct value tho.

58 boots past PS2 logo. No change in graphics, still broken and crashed the emu the moment I would have taken control in the fight.

0_0 That make no sense. Emulator just can't delay something by 0.58 cycle, cycle counting accurate like that will make it slow af. No idea what's going on, but i'm sure it use 0.58 value as something different.
I will try to dig in emu code later to see how parser read that value. Because this just can't be possible from coding pov.

Edit: It even say in emu code:
--vu-xgkick-delay',0
'vu_cycles/integer`

Integer can't store values that are not whole numbers

Fix for SecondSight (SLES-52670) should work with NTSC too.

The game is beautiful ! Thanks a lot.

A large number of commands for text repair are basically universal as long as the code is not involved. This is the experience in repairing PS4 emulation PS2

But crash when launch a race.

You can try add this as LUA, game is known to require VIF fifo. Original patch by prafull.
SLUS-20584 only.

Code:

apiRequest(1.0)

local emuObj      = getEmuObject()
local eeObj       = getEEObject()
local patcher = function()
eeObj.WriteMem32(0x22b4a4,0x0)

So if i didn't make any mistake, pcsx2 won't help here.

Here is some fun for people that like 2D games, but not only.

Scanlines enabler config

Yup you read it right. For now you need to create pkg manually.
Properly named lua config goes as usual to patches folder. shader_SL480_p.sb file need to be in feature_data folder in root of game file structure. You can also put there lua if you prefer that way. Just name it XXXX-YYYYY_features.lua (your game id of course).

Remember to unzip it first. And that's all, we got working scanlines filter

Scanlines can be edited like you can see in config. Count/Height/Strength etc.
Big thx to @Stayhye for testing, and his contributions to ps2onps4.

Code:

apiRequest(1.6)    -- request version 1.6 API. Calling apiRequest() is mandatory.

local eeObj       = getEEObject()
local emuObj    = getEmuObject()

local goatman = 0
local sprite0 = getSpriteObject(0)
local sprite1 = getSpriteObject(1)

Global_InitGpuResources = function()
    -- # Fragment Shader 0 is fixed as the default no-thrills as-is renderer.
    emuObj.LoadFsShader(2, "./shader_SL480_p.sb")        -- (2) = 480P ScanLine Sim
end

local scanlineParams = {
    240.0,        -- float scanlineCount
    0.7,        -- float scanlineHeight;
    1.5,        -- float scanlineBrightScale;
    0.5,        -- float scanlineAlpha;
    0.5         -- float vignetteStrength;
}

local scanlines_moder = function()
    if goatman == 0 then
        sprite0.BindTexture(0)
        sprite0.SetPosXY((1920-1440)/2,0)
        sprite0.SetSizeXY(1440,1080)
        sprite0.BindFragmentShader(2)
        sprite0.SetShaderParams(scanlineParams)
        sprite0.Enable()
        sprite1.Disable()
        goatman = 1
    end
end

emuObj.AddVsyncHook(scanlines_moder)

Keep in mind that if you want to combine this config with for example wide screen patch, you need to add new lines, not embed it into that one. For example combined config for
Hunter: The Reckoning Wayward [NTSC-U] (SLUS_205.11) will look like this.

Code:

   240.0,     -- float scanlineCount
     0.7,     -- float scanlineHeight;
   1.5,  -- float scanlineBrightScale;
   0.5,  -- float scanlineAlpha;
   0.5  -- float vignetteStrength;

     sprite1.Enable()

   end
end

just replace

with your own. Big Thx to @kozarovv for script to build on.
