My ball sprite was chomping up an eighth of my 4K and I was starting to feel cramped for space, so I had to make a design decision. Now it's only a sixteenth of my ROM.

(Which hasn't stopped me from coding a LOT of low priority features before the high priority ones) Hehe -Lee >From XXX Wed Sep 01 15:45:14 2004
