Pressing X+UP, X+DOWN, X+LEFT or X+RIGHT does nothing and pressing SELECT + Y also does nothing

Use the latest build from the Actions tab above.

I have a question when reading the source code. With scaler = 0, why not transfer the texture at 0x1820'0000 to the screen framebuffer, but process the texture from gpu command list and then transfer the framebuffer at 0x1818'0000? What will happen if using the first solution?

profi200 commented 1 year ago

I don't quite understand your wording. I can't skip any of the steps because the frame coming from the hardware is in a different orientation than what the physical LCDs on 3DS use. So rotation is necessary. The GPU is also unfortunately tile based so all textures processed by the GPU are swizzled which makes the display transfer at the end necessary to unswizzle.

@profi200 The build artifact expired; is there any way we could get another build there?

Thanks!
