@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.
@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.
@root I tried this one too, but it only outputs c64 file formats (or executables), and the result isn't great:
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."
