Wow that is some bundle collection game you have there, and it’s made in Pico 8? Amazing!
What’s the code for adding all your pico 8 games in one cartridge? ‘Cause I like to make a bundle collection game like yours too? How did you do it?
the pico manual has a nice breakdown, but you can basically list multiple ROMs in one export call to make sure the resulting output (whether its web playable HTML or native binaries) includes everything you need to support LOAD() calls in your games... you can even pass in an automatic "return to launcher" type menu option when you load those games. pico8 is so good!!
