    If you want to access the 256(!) extra glitch levels in Super Mario Bros. you need to go find yourself a top loading NES system and a copy of Nintendo TennisPut your Mario cartridge in, then take it out with the system still on. Put the Tennis cartridge in, then reset. Serve once, run around for a bit, and then take Tennis out with the system still on and put Mario back in. Reset Mario, then press both A and start at once and you’ll be on one of the 256 glitched out “secret levels."

    Super Mario Bros. Was Meant to Be the Last Cartridge Game EVER

    Before becoming Nintendo's first big hit in America, Super Mario Bros. was supposed to be Nintendo's cartridge based ride into the sunset before they switched to the floppy disk-based Famicom Disk System. Ironically, the game was so popular that cartridges stuck around for another two decades.

    Shigeru Miyamoto initially sketched Bowser as an ox. His drawings were misinterpreted by animator Yoichi Kotabe as a turtle, but then the duo worked together to mix the two ideas and the Bowser we know today was born.

    Mario Was Named After Nintendo's Landlord

    Long before Mario was Mario, he was called “Jumpman” because they had to call him something. Before that, he was called “Mr. Video” which is actually kind of awesome. Even before that, he was known as “Ossan,” which translates to “middle-aged guy.” And because no one wants to play a game called "Super Middle-Aged Guy," a proper name was sought and found in Nintendo's American offices.

    The story goes that Nintendo was supposedly late on rent and their landlord, Mario Segale, looked the other way. In thanks, he was forever immortalized as the namesake for the most popular video game mascot of all time - Super Segale.
