Game Genie Cheat Codes Super Mario Bros

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.

The following codes are useful with Code 20. 21 ZEUXKGAA Start the game as Fire Mario 22 LEUXKGAA Start the game as Raccoon Mario (tm) 23 GEUXKGAA Start the game as Frog Mario. Cheat codes are built-in cheating mechanisms in video games that usually give the player considerable advantages, such as the ability to skip to any level regardless of progress, invincibility, or power-ups to the player character. Cheats are typically activated with unprompted button sequences in the game's menus or by accomplishing an obscure or illogical series of events within the game. I just got a reproduction copy of the Japanese version of Super Mario Bros. 2 for NES at Midwest Gaming Classic this weekend. But it is, as I expected (and, actually, KNEW from playing it on the SNESs Super Mario All-Stars), insanely difficult. Are there any Game Genie codes out there.

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.

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:
