Do you remember the stage altering codes for SMB1 for NES? Well, I may have stumbled onto a few of them for the SNES:

Note that these codes will not allow you to play straight through the game. At some point, you'll get stuck.

Super Mario Brothers

All stages are underwater 1
A3A0-D7BD
NOTE: The stages are in a different order too.

All stages are underwater 2
A3A0-DFBD
NOTE: The stages are in a different order too.

Stages are played in a different order 1
A3A9-D7BD

Stages are played in a different order 2
EEA9-DDBD

Always play on Stage 8-3
A3A9-DDBD
NOTE: There is one point where you'll start in an underground area, but when you go through the pipe, you'll reappear in Stage 8-3.

Different enemies on stages
A3A9-D4BD
NOTE: When you get to Stage 1-2, you'll notice rotating fire bars, then you'll come across Bowser. However, once you reach the end of 1-2 (where the pipe is), you'll reappear at the start of Stage 1-2.

Weird Worlds 1
A3AE-D7BD
NOTE: Make sure that you have a high jump or swim everywhere code active. There are areas that require you to jump much higher than usual. Even if you get past the stage, you be stuck. Also when you die, it may start you out right over a pit. If you have the mega-jump code active, if you time it right, you can jump before you start falling & make it to solid ground.

Weird Worlds 2
A3AE-D4BD

-------------------------------------------------------------------------------------

SMB: The Lost Levels

The ground is missing
A3A0-DFEB
NOTE: Like the one found for SMB1, you need to activate the swim everywhere code (DFB3-6485). You won't be able to clear the first stage because you'll fall after you hit the flag pole.

Stage 1-2 is very different
A3AC-DFEB
NOTE: This stage has a Goomba, a beetle, a koopa troopa, a hammer brother, & even a few of the characters seen on the swimming areas. It looks like a glitched swimming stage, except that you can swim. You'll also need to activate the swim everywhere code (DFB3-6485) because there are areas that you can't get past with regular jumping.
