Emulator

What's the problem? Describe what went wrong.

On Wii hardware, it is as if GX_SetCurrentMtx() is called corresponding to the last matrix sent in a draw containing matrix index data. Dolphin maintains the current matrix after these calls.

What steps will reproduce the problem?

(This is an example)

1. Load 2 different matrices into GX_PNMTX0 and GX_PNMTX1
2. Call GX_SetCurrentMtx(GX_PNMTX0)
3. Draw a model with no matrix index data. It will use the first matrix.
4. Draw a model with matrix index data. It's last vertex points to GX_PNMTX1.
5. Draw a model with no matrix index data. On Dolphin, it will use GX_PNMTX0. On hardware, it will use GX_PNMTX1.

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible. Screenshots showing what it is supposed to look like from either console or older builds of Dolphin will help too.

The black of the character's eyes is erroneously using the same matrix as one of the pupils, because GX_SetCurrentMtx was not called after drawing the pupils. It draws correctly on the emulator.
