This opcode pair is heavily involved in the RSP graphics ucode, so there should be tests for them.
Gamemasterplc did a widescreen hack with better HUD/borders support. Can it be applied to the LOD hack? https://www.youtube.com/watch?v=gN67svpB60E Thanks!
The VSAR/VSAW instruction is not fully explained in the RSP official doc, but it clearly shows that the vector source is always written into the accumulator after the read part....
From this test: https://github.com/PeterLemon/N64/blob/105fd6cfc3f863f0a128802a20ee1137907ba78e/RDP/16BPP/Triangle/ShadeTriangle320x240/Cycle1ShadeTriangle16BPP320X240.asm You'll find this line: Shade_Coefficients 256.0,0,0,0, 5.12,5.12,-5.12,0, 256.0
This work allows to measure SI DMA/IO speeds. It polls SI_STATUS and compute how many C0_COUNT increments have happened during DMA/IO transfer. Precision of timing is not absolute, as there...
This work allows to measure PI DMA speeds. It polls PI_STATUS and compute how many C0_COUNT increments have happened during DMA transfer. Precision of timing is not absolute, as there...
This is not necessarily an issue with the according [test rom](https://github.com/PeterLemon/N64/tree/master/RDP/8BPP/Rectangle/TextureRectangle/TLUT/InternalPalette), assuming the screenshot was taken from real hardware, but since the results are somewhat unexpected I'd like to at...
I have ran into the issue that the cart bootrom is writing 0 for osMemSize (vaddr A0000318) therefore breaking program execution, and don't know what is causing it. A test...
The current set of CP1 test roms all test against the FPU while using the default rounding mode: nearest. Having tests using the other 3 modes would be helpful: toward...
