@codewiz When I was searching for one, I ended up instead looking at instructions on how to accomplish that with gimp: reducing resolution and the colours does it. Should also be doable with Imagemagick.
In part, it's because nobody was doing Floyd–Steinberg dithering back in the day (ImageMagick doesn't have a lot of options).
In part, it's also because the #C64 was constrained to 4 colors per character cell in multicolor mode.
@globalc @[email protected] Without dithering at all, it also looks wrong (any #C64 artist would have used some dithering):
@globalc @[email protected] I could make an animgif version using 60hz flickering to create intermediate color shades! #c64 #demoscene
@codewiz That's awesome!
I was just thinking if there were also some "typical c64 colors", one could mass-grab c64 game screenshots for that from the net and look at the used colors.. but your result here is already great!
@codewiz You could try with cutting down resolution a bit more. Cutting down colors might be harder.
@codewiz We didn’t have error diffusion algorithms like FloydSteinberg, got anything cruder?
This mcDRAW totally *RULEZ*!
But why mcDRAW and not c64DRAW? 😜

@codewiz Ahh, now that’s an era appropriate dither. Very nice.
The converter we used for 'trouwfuif' ( https://csdb.dk/release/?id=208435 ) is convertron3000 by fieserwolf; https://csdb.dk/release/?id=155606 . It outputs koala (multicolor) or hires, though I did not use hires. I tried a preview and after initial promising results, "oh yeah that was before color collision removal, hmm, yes, this is very... not the same thing."
