Check out this amazing guide that has insane undocumented tricks on Super Mario Brothers that exploit the Miyamotoness out of the game's bugs. The little animated gif you see above is but a small sampling of the insane ninja skills you will learn here, explained step by step with animated video for your cerebral absorbation. For example: Jump into a wall just below a solid ceiling and walk through it To perform the trick, do a walljump into the wall position right below the ceiling. When you get foothold, jump immediately. When you land, jump again. When you land again, jump again. Usually three or four jumps are enough before you can walk through the wall. Each jump takes you deeper into the wall. During each of the jumps, you need to steer heavily to the opposite direction you're going to. Otherwise the wall will eject Mario.
