I would use lookups.  You could have the macro assembler compute the rotation bits, but I wouldn't compute it on the fly in the game.  You'll have your hands full with updating sprites.

The cheap way would be to XOR the fireballs as an overlay.  It wouldn't look as pretty, but it would make it easier to redraw the screen (xor the old fireballs, update the screen, xor the new location of the fireballs, etc)

Your only other option would be to tag the surrounding blocks as "moved" so that you force them to be redrawn in order to get rid of the old fireball sprites.  This would allow you to draw better fireball overlay sprites but at a cost of a slower redraw.
