Basically the only difference between your method and the one I described
is that completely erasing the sprite then redrawing it will produce
flickering.  My way, or rather the way I described  gets rid of the
flickering without using the graph mem.  But as I said it is limited to
certain conditions: if there is a bg then you know what's covered and
can redraw only what's uncovered.
