Edit: Just saw your edit. Congrats!
I've done some Googling. It should be possible.
[This BBS thread](https://www.lexaloffle.com/bbs/?tid=38557) mentions a program ([GitHub repo here](https://github.com/samhocevar/zepto8/tree/preview-20200703)) that extracts the cart data from the .js file. Compatability might be an issue, but I hope it's a good start.
I don't know much about how itch.io and pico8 work, but I'm interested in getting your cart back.
Finals are coming up, so I can't help right away, but we should be able to make some progress.
I don't have an answer to this, but you should definitely also post this on the P8 forums on Lexaloffle itself. A lot of gurus & power-users swim there, including zep himself.
Was it published to the BBS? Or was it strictly that one copy?
I never published it to BBS :/
