This is an official education version of Pico-8 which allows for saving. Since Pico-8 can now be used for free, would that make it a potential official chiptune format?

years ago someone tried to fork tic80 into a pico-8 libre clone, i didn't try it yet: https://github.com/afonsojramos/feup-8

This looks nice. I've always wanted to see Pico-8 chiptunes, but it's kinda hard to find them. It was also not really a thing I had my mind set on since PICO-8 cost quite a few bucks. Maybe a format... *eyebrow raise* Definitely very cool.
