• 40k demo NES/Famicom Mapperless by Otomata Labs
• Quote:

  I'm quite curious about the 420 color screen, I understand what the code is doing but I'm not sure what I'm _supposed_ to be seeing. Composite artifact colors? Time-dithered blurring?

  
  
  It's using a hardware bug/feature that if all rendering is off and VRAM port address points to the palette memory, it will display the color of that entry as a background color. This is why there's a big PPUADDR read slide during active display.
  
  This effect, combined with color emphasis, had been discovered and made into a full color palette demo almost two decades ago. But nothing more had been done to it until now.

• NTSC NES / Famicom only. As official PAL machines have different PPU timings and we have to cycle count until the last line of raster effects :)

• 32k Atari VCS Twin by All You Can Execute
• This is a remix of original music and (barely) visuals by Petriform https://youtu.be/C0vqrmRgfM8. It is mostly a showcase of our new software pitch engine that expands the original 32 different pitches into 7937!
  
  Also this was ranked 1st in music compo. It's here because I added visuals to the ROM later ^^;

• Good to finally see a SNES demo, let alone the one that won the compo!
