[Seeadler]

Maybe!

In my widescreen dll I have hooked the DirectX function CreatePixelShader() and then dissassembled the buffer with the actual pixelshader code and dump it in a text file. Now I have every hardcoded pixel shader of SH3 as asm shader source code in separate files.

Unbelievable but SH3 uses only 5 pixel shaders

1 = shadow shader
2 = water reflection shader
3 = water shader
4 = terrain shader
5 = ??????

in comparison SH4 approx 200

Now in a second step I loaded this simple asm shader code

ps.1.1
tex t0 
mov r0, t0

from a file into the buffer and replaced the hardcoded water shader with it. This shader code simply takes the texture stored in register t0 and moves it to the output register r0



This is just a proof of concept to change the pixel shaders in SH3 from external files such in SH4/5. It needs allot more work, ...extend to shader version 2.0, make use of more texture registers, storing own textures in the registers and so on...
