  I mainly care about breaking assumptions in ways that inspire other people to explore new areas, as has happened successfully twice now.
  
  I don't hope this entry into the fight inspires people to make demos without sound. But there are plenty of opportunities for making sound without DMA. That would be a fresh take. :)

  Me neither, but even though it may not seem like it, it only has two channels and there are no pattern-effects. I don't know why Rhino asked me to make the music like that. Ask him.

  
  Because the audio DMA interferes with cycle-exact CPU code if you don't place your instructions properly.
  
  Instead of meeting that challenge and beating previous records, Rhino decided to tackle a different, easier problem.
  
  Hannibal still in the lead. :)

• demotool Amiga AGA Amiga OCS/ECS Cranker by The Electronic Knights
• Ah yes, if fast crunching on Amiga is also a goal, then ZX0 is not suitable, at least with the currently available implementations. I do think it would be possible to make a fast cruncher for ZX0 that would still compress significantly better than LZO, but that is obviously a lot more work.

• Have you considered using the ZX0 compression algorithm?
  
  It compresses the raw data of Retro Dentro down to 193301 bytes, which is more than 10% smaller than Cranker (even taking the 1100 bytes decrunch header into account), and it has a small (80 bytes) decruncher which can decompress that data in just 5 seconds on 68000, which should be plenty fast to keep up with the floppy loading.
  
  There's some work involved in adding chunking support to the decruncher, of course, but given its simplicity, I'd guess that's manageable. :)

  Are we allowing disabling some/all audio dma now though?

  
  No. ;)

  Is any of these attempts using the technique that Flash Production did in
  "Danish Knowhow" from 1990?

  There is a copper splitter on each 4 pixels.
  It uses 5 bpl with %00001111 masks to set all different bitplane 31 colors, and then it sets 32 background colors to see between the 4 px bitplane gaps.
  That makes at least 63 colors that way.

  
  Interesting. I count 52 columns on the effect.
  
  It's a pure copper display, running in 4 bitplanes and using DMA-sourced sprites for the upper colors. Since it's 4x1, not 4x4, there is no copper looping involved, so it just needs one WAIT per scanline on top of the color changes, leaving plenty of time to set 52 colors. The effect itself is drawn with the blitter.

• IIUC, the chipset emulation in the latest WinUAE is completely rewritten based on leaked schematics. :)

• The best part of record breaking is when assumptions are broken. Assuming there's only one way to make the copper loop. Assuming that all colors are written by the copper. Assuming that HAM can't produce crisp pixels blocks.
  
  Also what Leonard and Loaderror said. Every so often, people on other platforms brag about breaking emulators, but it rarely happens on Amiga.

  These width records are getting a tad ridiculous as we are approaching overscan territory...
