gSPDMATriangles about gliden64

[gonetz]

The current code uses the second nibble of the command to get the number of triangles.
As you can see, in command 0x05110020, it is also 2.
I checked, for command cmd, the second nibble is always equal to the sixth nibble + 1:
((cmd>>20)&15)+1) == ((cmd>>4)&15)
But if the ucode actually uses value of the sixth nibble, ok.

if 0, texturing is set off.
if 1, texturing is set on

I was not used. I added that code.

The rest is already implemented exactly as you described, see gSPDMATriangles function.

Fixed in commit b021d8e.
I don't expect any changes in Mickey Speedway USA and JFG, which use that ucode.

Super :)

I am going through the whole ucode actually. Interesting code, mainly when it comes to matrix and vertex.

There is not much difference with current implementation but there is some details which we can add, even if it won't lead i guess to much changes :)

@gonetz

actually DKR has exactly the same code for gSPDMATriangles. No distinction should be made here so between DRK and JFG.

Done.
