Hi Brian!

for my kernel?

No, of course not. I posted it, because I thought it 
might help. 

The general idea behind it should do, but I'm sure 
you'll have to spend quite some time to get all your 
writes done in time, matching your differing positions.

It depends a bit if buffering is needed or not. The 
spaces between your sprites might be just big enough to 
live without. You should try to start without it, maybe 
it just isn't necessary. Of course it doesn't make that 
much a difference if you spend your kernel cycles with 
TSX/TXS or NOPs, but it saves you the stack restoration 
outside the kernel / and you possibly might use these 
cycles to enable the missiles in order to use them to 
draw centered cards, as someone already suggested.
