Uh. I didn't mean pushing the entire table and the display shift caused by
that. I was referring to the ball (mouse cursor) itself which is jumpy. I
thought it should be stable and pointing at the same pixel, if the mouse
doesn't move?

If you can play the MNGs, you'll see what I mean.

Yes. I think I got the CRAM reads/writes and jumping to RAM/ROM code right
