I don't understand the question. Are you looking for a tool which converts images to 1-bit? With dithering to simulate greys?

This art is super cool, btw! Where can I find more?

yes I'm looking for C algorithms for that. I just searched for "1bit old-school image"

Search for Floyd Steinberg dithering. That's the algorithm used by a lot of classic Mac software.

This web utility seems like exactly what you're describing. I think this was a small app someone made for themselves while developing a game for Playdate. The source might be available on their Github. If not they seem friendly, you could ask for it.

It took me some time, but I realized they're asking "Does anyone have". I think.

They tried to use verb raising, which is where the verb is moved to the start of a sentence to ask a question. We usually only do it for "to be" (e.g., "is"), but we very rarely do it with "to have", so maybe that's where that came from.

(Think "John is good" becoming "Is John good?", instead of needing a question word or "do" at the start of the sentence)
