I understand what you were saying now. I've been thinking lately on vertical sprite re-use to create a status bar and ground objects; got confused.
I've never tried using the copper to re-use the sprites, but attaching 8 across the screen was one the possiblilites as I was 'writing up' the display attributes.
Been messing with the current display, scrolling it in 1 vbl, with the parallax layer and player sprites updating every 2. Working out the rest of the updates including synching the blits properly, but it's much smoother and runs well with 2 enemy bobs up. Trying this I also discovered a faster and more accurate AI routine which I can definitely use. It pays to go digging sometimes.
Your posts got me trying ASMpro again... ah, maybe one day.
