Twice,  load the coordinates and address pointer for the first sprite...call 
FastSprite...load the coords and addy for the 2nd sprite...call FastSprite
again.

What FastSprite does is... displays a sprite if it's not there already, or
erases it if it is there (all by way of XOR).  If you load the first sprite
and then load a different sprite on top of the first one, then you will get
a garbled mess.  FastSprite was made to be able to display and erase single,
non-overlapping, 8x8 sprites.  I made it for a Bomberman clone but abandoned
that project when BomberBlokes was announced.  (Have I talked enuf yet?)

Hope it helps.
