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.
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:
