yeah, as you probably found out, the only things interface-wise that you can edit are under pictures/game and include such things as cursors and window borders.

on the other hand, there are some odd little border things under general.bmp and also on the main list of component images that i always thought were just placeholders. maybe those are the mine / waypoint borders? probably not?

my money is on hard-coded, but you might want to experiment with those things and see if they do serve any real function.
