Last follow up: it doesn't depend on the GUI, the mouse still can't leave the top left 640x480 area (it is functional, but not drawn). Also, both X and Y viewport offsets are needed.

The mouse bounding box in PST is at

0x432300 => 640
0x432307 => 480

 

Let's see if I can find the various game bounding boxes too

 

EDIT: I appear to have found them. Unluckily, I can't get the action selection window (the one that pops up when you right click the game area) to display outside the original 640x480 box.
