(The Legend Of Zelda) Minus World & Minus Dungeon - Ram Cheat Codes

The Legend Of Zelda Overworld map is 16x8 in size, but there's more to it.. hidden. This new world is named the minus world!
A simple walk through walls code will not give you access to the minus world, you will need a brand new memory code.
Legend of zelda minus world was only possible with some cheats ;)

(PS. feel free to give me some blog advice)
