[UNOFFICIAL] Ishiiruka-Dolphin Custom Version

@masterotaku: if you give more detail on the values you tweak i can see if a native modification framework can be added internally to make thos changes more user friendly.
@Ramoth: interesting will take a look.

OK. Here's the content of a vertex shader that controls some shadows in Zelda Majora's Mask, called "36825a742c3b0f39-vs_replace.txt":

Code:

//Zelda MM: shadow behind maks in walls, Skulltulas house.
cbuffer _Globals : register(b0)
{
 float4 cproj[4] : packoffset(c0);
 float4 cmtrl[4] : packoffset(c4);
 float4 clights[40] : packoffset(c8);
 float4 ctexmtx[24] : packoffset(c48);
 float4 ctrmtx[64] : packoffset(c72);
 float4 cnmtx[32] : packoffset(c136);
 float4 cpostmtx[64] : packoffset(c168);
 float4 cDepth : packoffset(c232);
 float4 cPLOffset[13] : packoffset(c233);
}

Texture2D<float4> StereoParams : register(t125);
Texture1D<float4> IniParams : register(t120);

void main(
 float4 v0 : COLOR0,
 float2 v1 : TEXCOORD0,

{
 float4 r0,r1;
 uint4 bitmask, uiDest;
 float4 fDest;

 float4 iniparams = IniParams.Load(0);
 
 r0.x = 255 * v2.x;
 r0.x = (int)r0.x;
 r0.yz = (int2)r0.xx + int2(1,2);
 r1.x = dot(ctrmtx[r0.x].xyzw, v3.xyzw);
 r1.y = dot(ctrmtx[r0.y].xyzw, v3.xyzw);
 r1.z = dot(ctrmtx[r0.z].xyzw, v3.xyzw);
 r1.w = 1;
 r0.x = dot(cproj[0].xyzw, r1.xyzw)*iniparams.x;
 r0.y = dot(cproj[1].xyzw, r1.xyzw)*iniparams.y;
 r0.z = dot(cproj[3].xyzw, r1.xyzw);
 r0.w = dot(cproj[2].xyzw, r1.xyzw);
 o3.xy = r1.xy;
 o4.w = r1.z;
 o0.xy = r0.zz * cDepth.zw + r0.xy;
 r0.x = cDepth.y * r0.w;
 r0.y = cDepth.x + -1;
 r0.x = r0.y * r0.z + r0.x;
 o0.z = -r0.x;
 o0.w = r0.z;
 o3.zw = r0.wz;
 o1.xyzw = v0.xyzw;
 o2.xyzw = v0.xyzw;
 o4.xyz = float3(0,0,0);
 return;
}

The ASM code at the bottom doesn't need to be touched. Only the HLSL part.

The important (and almost only) lines that I modified for the aspect ratio correction are these:

Code:

r0.x = dot(cproj[0].xyzw, r1.xyzw)*iniparams.x;
r0.y = dot(cproj[1].xyzw, r1.xyzw)*iniparams.y;

"iniparams.x" and "iniparams.y" are variables that I defined in the "d3dx.ini" file that comes with 3Dmigoto. I use a variable so I can change its value in real time with a hotkey, for aspect ratio changes in real time. However, that makes it work only with 3D Vision.

If I put the value manually, like "r0.x = dot(cproj[0].xyzw, r1.xyzw)*0.75;" (correction from 4:3 to 16:9. Lower values for wider aspect ratios), it works for all users even if they don't have 3D Vision.

The thing is that all vertex shaders that I modified for aspect ratio mods needed exactly the same changes. The "r0.x = dot(cproj[0].xyzw, r1.xyzw);r0.y = dot(cproj[1].xyzw, r1.xyzw);r0.z = dot(cproj[3].xyzw, r1.xyzw);r0.w = dot(cproj[2].xyzw, r1.xyzw);" lines are always there. So if I had access to the source of the projection, I would be able to change all shaders at the same time.

Ideally, it would be like an improved widescreen hack that works with every game and leaves the HUD and menu elements with the correct aspect ratio. If it were done that way, I don't know if I would still need to make exceptions to some shaders (in some cases, some shaders needed to apply to the entire screen and not be corrected. Exceptions that do need 3D Vision to work because they use variables).

Hey Tino, I found another game with weird depth access Geist . So, while your in a cutscene, ssao/SSGi works perfectly fine as it should, but while in gameplay, it only shadows a weird line in the middle of the screen and not the environment. o.o

EDIT: It got much weirder. I'll post a video in a second.

[Ramoth]

More universal widescreen hack from PCSXR.

@rlaugh0095: one of the post processing shaders is called Depth please select that shader and send a screenshot of the output

Tino ive got a question. would the changes made to this version of the emulator cause TAS to desync? Cause i want to make TAS but play it back using ishiiruka so that i can have that glorious quality.

[Tino]

@CowlScatman: no idea never tested, you will help me if you test and let me kenow if you have any issues

i maid a quick TAS this morning using ishiiruka and when i tried to play it back it just gave me a buzzing sound. Im gonna try it without the shaders enabled.

[CowlScatman]

Okay so the emulator itself just doesnt want to play back TAS input apparently. The game screen just turns white and buzzes as soon as i click it.
