Description
PSX has a Geometry Transformation Engine that is capable of doing multiple matrix operations. A lot of games uses this to speed up their math, and in assembly it becomes the "cop2" instructions. no$psx has a similar feature where you can open a window to watch the GTE registers changing in real time as you step in the instructions when debugging. Adding this feature would be essential to debug these instructions.

Research direction
No file, test, or entry point is named. Start by locating the PSX debugger and its cop2/GTE handling, then review how debugger windows expose live state. Done means a debugger window can show GTE registers updating while stepping through PSX instructions, with the behavior verified against the existing debugger workflow.
