Top 10 Weird Super Mario Bros. Game Genie Codes

I’ve always been a fan of the Game Genie, more specifically the Game Genie for the Nintendo Entertainment System. When I was younger, video games were a lot more difficult than today. Usually a couple hits and you’re dead, 3 lives and it’s game over.

Being able to save your game, or even have continues wasn’t usually standard. Some games did feature Passwords, but more often than not the piece of paper you’d scribble your codes on would end up lost, or in the trash.

Needless to say most people wouldn’t usually see the ending to most Nintendo games. That is until the Game Genie made it’s appearance.Game Genie Logo

Normal uses of the Game Genie were to give yourself more lives, infinite health, or infinite ammo. Not so normal uses (and what absolutely fascinated me) were to change level designs, alter the appearance of sprites, and basically just cause strange things to happen.

A long time ago I would create and collect these strange codes, and post them online on my old Geocities website. Having recently rediscovered my old Geocities website, I was inspired to share some of my own personal favorite codes.

In the video above, I narrowed hundreds of Super Mario Bros. codes down to my top 10 favorite:

#10 EVYIVY – Everything bounces when it hits the ground

#9 PIGNAX – Invisible Mario – Really changes the gameplay

#8 GAYSUK – Run off a platform and keep running in the air

#7 VGPNYA – Weird stuff comes out of power ups

#6 STAGEO – All bad guys throw hammers

#5 EKGAIS – CRAZY Cartoon colors

#4 PIGPOG – Spawns random enemies and obstacles

#3 NULTKA – All enemies are Toad

#2 NAPSIN – Kill all onscreen enemies with firepower

#1 YEAAAA – Very, very wacky craziness!

For this list of codes I used the US Super Mario Bros. / Duck Hunt cart. If you’re having problems with these codes make sure that’s the version of the game you’re using.

Here’s the list of codes from my old website:

  1. I discovered a new Game Genie code for SMB1:

    LRLFLS – When collecting a powerup or stomping a enemy the Score Obtainer bar goes up faster (i mean the ones that say 1UP, 1000, 100, 200, etc) but while hitting a coin block it goes up at the normal speed

  2. 6:28 SEVERE CORRUPTION LATER… ERROR NES CORRUPTED NOW EXPLODING IN 5,4,3,2,1,DFDGYNSDYFUGFVSGYUBFBSGVYBGYBFVS,0…
    BOOM! HAHAHA!

  3. AAANAY: Forcing the game to start makes Mario invisible and the game freezes. Turning the code on during gameplay does the same but Mario doesn’t turn invisible.

  4. GPILNK – Some powerups are missing, others will fall from the top of the screen after you hit the block. Might make a full game run more interesting.

  5. GOATSE: Though it shares the name of the infamous shock site, this code provides an interesting effect and a great deal of challange. Enemies and some objects are invisible, but their graphics and animation appear on the left side of the screen.

  6. SOLALI:Mario’s form resets back to Small without changeing size when the level/level segment changes, i tryed somari but no m and r so solali it is

  7. if you use PZZONO + PIGPOG + NAPSIN +NULTKA its so damn funny. and if you check all the pipes, you can warp to 2-2 and then finish it you go to 1-4 then fight bowser (NO BOWSER!!!) you just go to 2-1!

  8. My creations
    PIGSUP – The game doesn’t stop if you die via enemy. The clock will freeze and sometimes the screen but it only lasts a few seconds before everything will move again. You will get the death music but still be alive. Falling into pits and lava kills you, Time up is broken so you need to turn the code off during play if timed out.

    1. GSLLEK – Mushrooms will move randomly but are easier to get.

      GELLEK – Frozen mushrooms

      SINPLS – only use once then turn off when you die…
      On world 1 – 1, go down the 1st pipe for an infinate coin room. Eventually the time will run out, turn the code off and then enjoy near infinate lives.
