I'm just making this thread so that people can post good map codes they found.
for example, the map with the most land, that way it's fun for digging tunnel, or with the less land, to push worms into the water.

I also have a few questions:
Has anyone invented a program that let's you fill in options and it gives you the correct map code? That way you could kind of create your own maps

Is there a way to put new maps in the game, through your memory stick?

Next time, try searching. There's loads of threads made for the map codes stuff.
