Super Mario Bros - Level Modifiers Game Genie Codes (World)

This page contains the Game Genie codes I have for Super Mario Bros (World), a game for the original NES (Nintendo Entertainment System). If you're playing with an emulator you'll typically be able to put these codes into the program directly through a built in option. Any of you who are old school and playing on a physical console, you'll have to purchase a physical Game Genie cheat device to use these codes.

If you don't see the code you want on this page, I recommend you return to my Super Mario Bros Guides Index and choose a different section.

 

1-2 & 4-2 Warpzone is 2,3,4. End of 4-2 is 0-1: XKNOPVEV
You can warp backwards if you want. At the end of 4-2 is the pipe takes you to 0-1 (this is different than -1)

1-2 WarpZone is World 5 or -1: AENOAVAA

8-4 Does not loop: AVEKGASZ
All parts of the level connect

 

Strange Levels
Use extra codes, for timer, pits/jumping, and level skipping.

OZEOKKZX
LAEOSKZZ

 

WarpZone is 6,7,8
This works for all zones. At the end of 4-2 you can only go to world 7

AENOAVAA
AENOYTPA

 

Start on 1-1 (Bad Rom Fix)
When SMB first loads, it reads the address DEFAULT value of $013E.
On some emulators the default is 0, and others it's FF (negative world)
