• Thanks for the info Blueberry. I wasn't paying attention to skips and jumps taking longer than a move. You're workaround is very clever.

  Wanted to correct that and say it's staying up for 4ish seconds.

  ... maybe something like an extra move (nop) after two lines in order to waste some extra time (2 cycles) ...

  
  
  So, yes I'd been trying exactly that, one nop every other line. It definitely works, you can display 56 colors on each line.
  
  The problem is that without the loops your code now has to fill all four rows with color data. With all the bitplane and copper activity there just isn't enough bandwidth to do that.

  Any bean-spiller intentions and willing to give a hint?

  
  
  In fact there isn't enough bandwidth in Blueberry's version to run the rot-zoom and fill just 54x71 colors.
  
  This is where Photon's version has an advantage, he has less bitplane activity because he's using the sprites in place of the right-hand side of the image.
  
  So, how is Blueberry's version running at 50hz? Well, notice that it only stays up for at most a second of activity before the screen goes black again.
  
  From what I can tell Blueberry is pre-filling a huge ring buffer of copper lists, then when the effect runs the code tries to keep filling but eventually the display drains the buffer and that's when it goes black.
  
  So, does that really count? I don't know, I really love it all the same!
  
  I'd love to hear from Blueberry, especially if I've gotten that all wrong.

• I’m pretty sure I know the main trick being pulled here. Very sneaky! Does it count as a record?
