You know, I had remembered that as being some playfield-only monstrosity, but I just put the cartridge in and it does have three 16-pixel-wide shapes per scanline like I was planning to do, but they're not tightly spaced like the standard 6-sprite approach. All the shapes seem to be bilaterally symmetric, so I'm guessing both players are set to wide spacing and the same data is being put into both of them, and the intervening 16 pixel space gives enough time to do an indexed load. It looks like there's something going on with the vertical delay registers, too, because the right two digits of each player's score are offset by a scanline from the left two digits. Hmm. Gee, I hope mine wouldn't have looked as ugly as this if I had gone ahead and written it... eric -- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/stella.html
