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.

When it comes to emulation for the NES you have 3 good options to choose from. You can do RetroArch, Nestopia or MesenCE, follow the links provided to learn more about how to use the codes you find on this page on the Emulator of your choice. 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)
