But that means you pretty much can't do any branching during that scanline, unless you want to go to great difficulty to make sure the cycle counts always work out the same. It works for the invaders thing because during the display kernel (actually, Piero, during the first scanline of each pair used in the invaders), all I'm doing is loading, rotating, and storing data rather than checking and branching. -- Stella list is Administered by krishna@xxxxxxxxxxxx <Glenn Saunders> Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/stella.html +-shameless plugs-------------------------------------------------------+ | Stella documentary at http://www.primenet.com/~krishna | | Nick's VCS links via http://www.primenet.com/~nickb/atariprg.htm | | Write the best game, win framed autographs of famous Atari alumni!! | +-----------------------------------------------------------------------+
