Some additional notes I have for anyone who wants to investigate further:

8100h appears to store the y coordinate for the mouse (LCD driver style)

8101h is the x coordinate (byte aligned)

986Dh holds the actual pixel coordinates. Or maybe it's 8122h. Not sure.

When it paints the mouse, it seems to store a copy of the former background to 811Ah

This routine loads data to 0032h and 000Ah. Yeah, ROM. I have no clue.
