Heh....more codes. Looking on the internet, i found some more codes 
. Here are some world codes...I should post all of it...since who knows when i will write more codes...but i wont XD.
World Codes (Teleport to other worlds 
Jokered with R2
When you pick a place and world to replace both XX and YY, go to the place you picked for XX, then move
to another room, before entering (Like a second before entering and you see the white letters
for the room name) hold R2 and run to the exit.When the screen turns black, wait a second, then let go of
R2. You should teleport to the room and world.May take a couple tries with the timing.
XX=World (Ex. Twilight Town) YY= Area (Ex. Main Island:Shore).Some areas seem to be impossible to
get to unless in the same world...
Press R2 to activate:
