I'm repositioning both sprites, Setting REFP0 & REFP1, 
setting three sprite, one color and one delay pointer, 
write the background color. While I'm doing this I'm 
taking into account the current "sinklevel" of an object 
for both the colorscheme and the spriteshapes. Not to 
forget, I'm also drawing the torpedos on (almost) every 
line and take care of an overall scanline count. Also 
I'm losing up to two scannlines worth of cycles before 
and after the WSYNC'd block.

Hm... :-)
