    the door goes back to mario s bedroom, you know... because the whole game is a dream
  • @WrestlingBios
    The amount of times we've came out of that door without ever thinking about going back in. Great work Gruz!
  • @bld9826
    So there's nothing behind the first door unless you edit pointer values, in which case any door could get you the same values.
  • @agustinvega8969
    As a kid I was mesmerized by that door and I would always try pressing up right before I started falling to try and get in. Good times. Thank you for this video!

    3:09 "This SMB2 editor is ancient dating back to 2002!' Lunar Magic: Am i a joke to you?
  • @davidjsaul
    "this editor is ancient, we're talking 2002". Me, born in the 80s: sobs
  • @MotherKojiro
    The "real" answer was a little disappointing, like when I found out that disabling the kill check at the bottom of the screen in most games just causes your character to wrap to the top, but the corrupted world was a thing of wonder; you sure know how to show a gal a good time!
  • @JulienNeel
    Thanks for nerding out with more technical explanations as to the how and why things glitch. You struck the right balance in this video for me. As always, your narration flow is spot on. Honestly you could comment just about any crappy old game and it would still sound fun. Great work man.
  • @Shadders2010
    That guy's intro perfectly expressed what my brain has been saying since I was 8 years old.
  • @Geno2733
    That editor looks like a very rudimentary version of Mario Editor.
  • I spent much of my childhood obsessing, wondering, imagining what could be behind that door. I would stare at the booklet, fixated upon the official art piece depicting mario walking up that staircase toward the door leading to subcon. Now I have an answer. Thanks for the closure.
  • @DaringDramis
    I've never wondered where that door might lead to... That's very interesting! It's like the programmers purposely set the pointer to get back to the same room, preventing it to be set at a random value and cause fatal errors, just in case a player accidently (or not!) succeed to enter the door. A good programmer habit to initialize all the variables in the very first place!
  • Did y'all ever think in a million years that all our childhood questions would be answered on a website called YouTube 🤔?
  • @evdestroy5304
    Err, this looks like it's just a level editor glitch and not actually what happens behind the door.
  • @rexrabbiteer
    As a kid in the early 90s I recall a friend telling me that you had to press up on the d pad at the right time to enter that door, he told me there was some sort of cave area in there
  • @gus_0065
    the door leads to mario's messed up dreams that he doesn't want us to see.
  • @AmyraCarter
    Falling down a waterfall, only to get trolled by a bottomless pit in the next room when you thought it was safe, is next level trolling, lolz
  • @kevinplayer2625
    A similar situation exists in Mario 3. You can turn tiles on the map to enterable tiles using game genie codes. For instance the start in world 1 takes you to an unfinished ice world. This is probably well known, but in 1990 something, it was pretty sweet.
