If you want to use the ball, the way you do it is to not do a solid beam. Do a dashed line basically, so you are only doing one ball per scanline. The dashed lines would not line up perfectly. You'd start the left or the right side earlier than the opposite side. You'd have a slight timing issue there because of the two lazy cannons, but I think it would animate nicely, especially if the gap between the dashes got smaller as the lines converged, as you'd have an extra hint of perspective that way (think Babylon 5 Star Fury here). You might be able to get away with it if all 4 cannons fired in series so there is always a slight delay between each cannon.

If you do it in playfield it's going to be blocky and might be more difficult to update in the kernel vs. the ball.
