A base cart with the TV already all done and a bunch of instructions on where to put code will be given at the very start of the jam!
And also the TV will be costumizable and that's what I'm showing off in this GIF with a Strawberry™ TV I made tonight!
Both this TV and the regular one will be given tomorrow at the start of the jam.
The jam will run from January 14 - 00:00 GMT to January 22 - 24:00 GMT. You do need Pico-8 to participate.
All the info for the jam can be read on the announcement thread on the Pico-8 BBS!
