Or perhaps ... that should be Co-Creationism ? :)

I've come across this helpful site with 2 curious pages:

https://neko250.github.io/pico8-api/#coroutines

While these commands are listed in PICO help as part of updates, no information is given as to what they do or how to use them.

The other curious bit from there is a POKE chart. I tried poking numbers into these and plotting sprites and text afterwards in an attempt to get double-size pixels; they all appear at normal size.

https://neko250.github.io/pico8-api/#peekpoke

A fully working example program for either of these would be immensely helpful.

One more thing, perhaps a little simpler. Is there a way to retrieve the current X & Y of where the text cursor is currently in a cart (Prior to PRINT()) ?

These are very useful cheat sheets, thanks for the link! I don't have answers for your question, though, sorry.

Glad it helps. I'm still wondering about that set of coroutine commands and poking to change zoom level of the screen.
