Displaying position when scaler=0

[a92126]

When I set the scaler to zero, the image with original size is displaying in the bottom of the top screen.

Is there a way to make the image displaying in the center of the top screen? Or some source code to generate the gbaGPUInitList?

The code used to generate the GPU command list is here. However open_agb_firm does patch the cmd list at runtime and multiple addresses in the cmd list need to be fixed.

Since i have no proper GPU driver yet adding more patches for centering would be a bit much.

From the source, the scaler 0 and 1 implemented by command list, and 2 by legacy frame buffer translate. The output will get some burrs on edge, which cause by the lack of sampling. I wonder if a pixel shader is possible to filter the source of gba video. I think a scaler of 3 can apply a xBRZ shader to create a 720x480 render target and downscale it to 360x240.

Unfortunately no fancy shaders are possible. There are only fixed fragment shader stages (6 tex envs). No real fragment shaders. I wanted to do a GBA color shader similar to what mGBA offers but it's very tricky to do without fragment shaders.

No reason to close this. The original request of centering the output is valid and doable. It just won't happen for a while.

Oh, I forgot the original request. Thanks.

this is fixed now, isn't it?

I guess? But it's still hardcoded.
