Make "Slave of the VU" work.

Worked a little bit more on the reflection tables for the VU Upper and Lower instructions today. I might have all of the instructions used in this microprogram disassembled for tomorrow.
I'm still not really sure how the VU is supposed to send vertex data to the GS. I've seen that the microprogram uses the FTOI4 instruction to convert the vector to a format that's near to the format used in the GS XYZ2 register, but I don't know how it can generate the actual GIF tags without shift instructions. Anyways, I guess that'll clear itself up once I finish the disassembly. |
