This opcode pair is heavily involved in the RSP graphics ucode, so there should be tests for them.
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
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...
I think testing against Coprocessor 0 such as exception handling, interrupts, reg transferring, TLB, MMU features, etc would be pretty helpful. Thanks!
With the screenshot I can compare my values against the expected values.
This is a tracker for incorporating the RSP into the emulator. * ~~Implement MIPS 4000 instructions.~~ * ~~Handle halt/break commands~~ * ~~Support SP DMA~~ * ~~Implement the 128-bit vector unit...

If the CPU is running a lot slower than the VI, lots of issues happen in OS threading such as audio tasks preventing the game thread from doing much or...
