This trick requires you to constandly hit the RESPx registers.
Since there three pixels for every processor cycle, you can't get
8-pixel gaps between the sprites. If you used both players and
positioned them in turns, then you could get 18 sprites in a
scanline with 9-pixel gaps between them. I think this is the
maximum number of sprites that you could get out of this trick.
