As we all know in NSMB Ds there is a World Map at the bottom of the Screen.

(I would add a picture but I have no clue how :p)

It's always been my dream to make a mod that adds a 2nd Row of worlds. Or atleast a "page 2" button beside the world.

E.g; World 9 - 16.

Does anybody know how I could add these Worlds?

I know it would be alot of work but im willing to put in the effort. (Unless its viruses..)
