   As long as the doves stay in the sky and the fire stays OUT of the sky and   
   away from the ground, they might have used vertical interrupts to switch   
   sprite sets as the electron beam hit certain parts of the screen. Think of it   
   like a layer cake. Each    
   layer can have up to eight sprites which are independent of the sprites in any   
   other layer. On the 64, the layers can be different widths. You can have   
   dozens of sprites on the screen at the same time but each group of eight can   
   only stay in its own    
   layer.
