Lossy compression for NES screens

A mirror of this script with improvements from tepples is located at my personal site: jrtilevq.py

In case the original Tweet disappears, the drawing is mirrored on Danbooru at https://danbooru.donmai.us/posts/2178017

illustrator: Kiyohiko AZUMA
series: Yotsuba&!
characters: Yotsuba KOIWAI and her teddy bear Duralumin
Mirror's translation of caption:

Yesterday's daily calendar image is "A pair of slime sisters who mimic another party's form and appeal to friendship, Youtsuba somehow figuring it out, and Duralumin not understanding a thing."

EDIT: I missed something. Clarify purpose of this post in light of this.

The first post in this thread already contains a link to the source, and it's the artist's Twitter account instead of a reupload on an image gallery...

Oops, my fault. I misread something. Clarified.

A much improved rewrite of this tool which is orders of magnitude faster, slightly better looking, and can handle tile flips, can be found at https://git.jroatch.xyz/jrrtilevq/
