• Indeed there was a gap to be filled here, for two reasons:
  - Cranker is designed to be fast at both compression and decompression, ruling out compressors like ZX0, which rely on a heavy, (near-)optimal parse by the compressor to achieve its good ratio.
  - At the 64k size target, decrunching while loading doesn't make that much of a speed difference relative to just having a fast decruncher, so it makes sense to avoid the complexity (and thus size overhead) of decrunching while loading.
  
  Speaking of ZX0, I find it quite amazing that it often beats DEFLATE even without entropy coding of literals. Just goes to show how awful DEFLATE is. ;)
  
  With a decompressor size of just 78 bytes, I would guess it can sometimes be competitive at the very low end, like 1k, especially if you add a mode without relocation support, like Shrinkler's MINI mode. I have been contemplating using it (or something like it) for bootblocks.
  
  How often do you see DEFLATE having a size advantage over ZX0 for 64k when the decruncher size is taken into account?
  
  Feature request: manual choice of compression algorithm. Presumably, DEFLATE decompresses much slower than ZX0, so I wouldn't want that to be picked by accident.
  
  Which other compression algorithms are you considering?

• 8k Windows ܲ by Nuance [web]
• Just wonderful! The whole setup, the colors, the lighting, the progression, the tight connection with the music.
  
  As others have pointed out, it's quite painful to watch in 30 fps, so I made a 120 fps capture. All hail kkapture. :)

• It was fun to reflect on the whole rotozoomer saga in this format, and to read the perspectives of everybody involved.

• Succeeds in conveying an impression of variety in the repeated animations. Also cool "fadeout" effect.

  Cool, I didn't know about the top bits in BPLCON4, that would be even faster!

  
  Yeah, the color switching provided by BPLCON4 is an extremely useful (and probably quite underutilized) feature of AGA. The layer polarity of the 8 layers in the checkerboard effect in No-CPU Challenge is controlled entirely through BPLCON4. :)

  I wonder why Blueberry saw 376 and you and Photon see 369. Maybe some hardware sees the hsync signal and use previously received colors on the hardware Blueberry used? This is fascinating.

  
  I don't remember exactly which hardware I used to measure the maximum width back then, but most likely it was a MicroniK SCANDEX scandoubler.
  
  I have brought my old 1084 down from the attic. It needs a bit of cleaning, but then I'll do some testing on that one and report back.

• It's a hallmark of quality when a prod entices you to fire up the DMA debugger. ;)

• I get this distinct sense of being very close to the copper when watching this. Very happy that it got second place. Well deserved. No-CPU ftw! :-D

• This race entered the ridiculous territory (in a good way) when it surpassed 80 columns. At least it's still displayable. :)
  
  Congratulations on your record, Hannibal!
