Glitched Worlds in Super Mario Bros! 

Someone just sent me a way to make some even crazier ones. Let me know if you guys want to see that 👀

The Kosmic Stream Starter Pack: ''I've never seen such a thing'' *geeks out over random, seemingly normal thing, then gives detailed explanation of how it's an SMB1 code oddity* ''That was(...), by the way'' ''BULLET BILL GLITCH-'' ''Oh hi, Bruce''. *does sick clip knowing darn well he'll softlock* ''I just died to show off (...), OBVIOUSLY''. (In the most casual tone possible) ''Okay, we're getting flagpole glitch''. *actually gets it and goes on with videogame normally* ''8000 KICK-'' ''Killing a Podoboo/Bowser with a star/shell, my favorite thing!'' ''UP AND OVER!'' ''G a m e d e s i g n'' *plays flawlessly on his first try, then dies trying to pull off some cool, frame perfect glitch and laughs adorably* ''We're playing a videogame?1?!'' ''We've got some blue lava...'' ''SHINY TEETH STAGE-'' ''No wait, take me back!'' ''I'm probably the first person to hit this block/grab this coin''. (FEEL FREE TO ADD MORE IN THE REPLIES)

9:13 World Among Us-1

This man has made a 40 year old game still entertaining to watch to this day. Props to you dude

7:08 when I was a kid I had one of those bootleg "200000 in 1" cartridges where it was just the Mario ROM but broken over and over, and I remember playing this "level"! :D And I remember wondering why it was unbeatable and made no sense. Good innocent times.

3:08 Those aren't the pixels of an enemy on the top. That's sprite 0. It just overlaps the bottom two rows of the coin in the status bar. (You can see it if you jump over top of the coin in the status bar during normal play.) Those pixels are what tell the game that it has finished drawing the status bar and can now reposition the scroll position in the nametables to show your position on the level map properly. That's how the status bar remains static while the level scrolls by below it. So something clearly broke the status bar and sprite 0 collision never occurred. When the collision doesn't happen, the game freezes. There are pixels of an enemy on the bottom right though.

It’s always special when we get to hear “My shiny teeth and me.” And the fact you have it ready on standby is even better.

What a great guy Bismuth is.

Hi Kosmic, I don't know if you know this, but sometimes you can win and see the next stage after touching a flagpole and falling into a hole... You'll just have to wait long enough, and Mario would fall from the sky, and if he touches a solid block, you'd win. :D

Back when I was a kid I learned hexadecimal and binary just so I could figure out how to generate all 256 possible warp codes for worlds -128 to 127. So, I have a full list of all those codes, but I still saw new stuff here, probably thanks to your other codes. Very cool! The ones where you have to go through 20 copies of 2-1 are the really annoying ones.

Its a shame weird glitch worlds like this wont happen with newer games

Between this and the Tennis glitch world video from Retro Game Mechanics Explained, RU-vid seems to want me to think about glitch worlds in Mario a lot more than normal. Not that I'm complaining - it's a fascinating topic

Wait bismuth is your editor? As in the bismuth who did the frameule, mario 64 tas explanation, and the mario 64 a press challenge videos? That's sick!

Here's a horrible idea: Someone should make a romhack, where you are able to select all the glitched levels, but all changes to the level gets stored back into the memory. Breaking a block? That's turning a 2 into a 0. Stomping a koopa? That's a 6 into a 5. And so on. (Values are guesses here) In the original levels, that would just mean permanent changes to levels. In the glitch levels, it would seriously mess up the game code :D

0:26 83-1 (Top left of question block) 0:40 84-1 (Top right of question block) 0:46 86-1 (Bottom right of question block) 0:52 88-1 (Top right of empty block) 0:55 90-1 (Bottom right of empty block) 0:57 92-1 (Bottom of right pulley) 1:00 96-1 (Top left of top left pipe block) 1:03 99-1 (Top right of top right pipe block) 1:07 124-1 (Top right of axe) 1:11 125-1 (Bottom left of axe) 2:33 127-1 (Chain) 3:17 129-1 (Top right of fence) 4:24 130-1 (Top left of water block) 5:14 131-1 (Bottom left of water block) 6:26 12:34 132-1 (Top right of water block) 7:07 133-1 (Bottom right of water block) 9:13 135-1 (Top right of top horizontal pipe block) 10:40 137-1 (Top right of top pipe junction block) 13:06 140-1 (Bottom left of top pipe junction block) 13:16 141-1 (Bottom right of top pipe junction block) 13:19 142-1 (Top left of bottom horizontal pipe block) 13:25 143-1 (Top right of bottom horizontal pipe block) 14:37 146-1 (Bottom right of bottom horizontal pipe block) 15:13 147-1 (Bottom left of bottom pipe junction block) 15:46 175-1 (Period?) 16:20 189-1 (Right side of the bottom of the tree (not the trunk part)) 17:08 191-1 (Right side of tree trunk)

Congrats to Bismuth! What a legend! P.S. I love how you spell out the level names. Starting a video with "top left of a question mark block dash one" is an experience.

7:32 is it just me or did the koopas go crazy just when Kosmic did the "woooo"? 😂

When I saw the thumbnail I thought of the older videos on the glitched worlds, then you mentioned them right at the start. Great video as always Kosmic!

I like how Mario just naturally jumps over the princess like " ... nope, gotta have a look into glitch worlds first."

I've never seen Kosmic as shocked as he was when that koopa threw a hammer

4:25 - Kosmic's reaction perfectly expresses the emotions I felt at the exact same time.

👏👏👏 for Bismuth

I laughed so hard when you killed the cheep-cheep with the block! 🤣

(6:40) I think you actually stomped that Cheep-Cheep, which is still quite cool in its own right, being in such a narrow passage like that. (12:37) Fun fact: If you wait long enough after falling into a pit during the flagpole victory march, the music will stop "hiccupping", and then Mario will eventually reappear at the top of the screen after a few minutes. (16:14) Combo with an infinite time code? Or a code that prevents you from dying to time up, perhaps? Bismuth certainly is a cool guy.

17:24 ''What makes me happy, feels me up with SPAAAAACE''

15:29 ''Like, there's just a floating block!'' In MY Mario? Impossible.

Just watched the other glitched worlds videos this came at a great time!

I honestly haven't played this game since I was a kid in the 80s, but the technical breakdown of all the glitches and whatnot is FASCINATING!

In this house we love and appreciate bismuth. Thank you both for all the great content you've provided

Reminiscing my 15 years playing this very nostalgic game (I was 5 back then), X-1 was the only glitched level I continouosly play/practice, though it's weird that my console already had the glitch worlds hack imported directly, and that got me to play all of what's available. Feels good barely remembering the levels from watching this and the other video you made with this years ago.

Someone should remake these glitched levels in Super Mario Maker

8:13 If you're interested, I recently made my own NES emulator with Game Genie support higher than 8 codes. Although if you're just using an emulator, I think Mesen already allows that, and it's more feature complete than my project. I think you're using actual hardware though? So an emulator probably isn't what you're looking for. Just throwing it out there anyway. It's all up to you!

It's a good week for glitched worlds! This video plus the retro game mechanics explained about Tennis and SMB!

2:13 *Local fish caught speeding*

I really like bismuth's style of editing. Congrats on the 100th video, thats nuts for you man

13:10 mario bonks his head so hard the universe crashes

Those glitchy worlds on super Mario Bros always let me call them world thundercloud🌩-1

More glitched worlds are always fun to see, lots of great moments in this vid ⭐

It would be so cool to see a mod where all the dungeon tiles are changed to cloud tiles because it looks great with the black background!

Hey Kosmic, just wanted to share a little story here, back in the mid 90s as I was in elementary school I had a couple of classmates whom we would exchange and borrow different famiclone cartridges between each other, one time I borrowed this famiclone cartridge which contained several pirated games (I’m sure you know the ones I’m talking about) and it had some of these glitch worlds, not every one but the more interesting ones from your previous video... For over two decades I’ve been wanting to replay those with no luck, until I discovered The Irate Gamer’s video about these glitched worlds, a few years later I discovered your video, thanks to your Game Genie code I created a Rom Hack that lets you skip to any world you want from the start including the glitched worlds, thank you.

That "Fish" at 16:32 is probably Gaster trying to break into the Mario games.

Congrats Bismuth. Love the glitches. SHINY TEETH!!!!!!

Running through memory sounds like fun! Maybe there is a unused hidden treasure world that was put in the game. Kind of like the movie National Treasure.

Mario says WOO at 4:52. Nice touch editor.

The crazy thing about the game genie,at least for the nes one, you can actually use 2 game genies connected together to use more codes

World B-1 was always one of my favorites, back when I'd modify the 3-line Game Genie code from my Camerica book back in the early 90s. Occasional random enemies helped to make it interesting once in a while.

More glitch worlds please. Thanks, Bismuth and Kosmic!

Bismuth edits for you and has time to make world record histories? Amazing!

1:40 I've began to make basic ROM hacks. And it's interesting seeing things like this make sense within the context of building levels

Ah yes the glitched worlds! Hello Kosmic it's been months! I stepped away from the Super Mario Bros and retro game world and instead am busy with school and am a competitive smash ultimate player. Hope you and everyone in the channel is doing okay.

love the secret worlds content! It really elicits a sense of frontier exploration for me

Bismuth truely is amazing

4:26 I love the frantic noises you make trying to get Shiny Teeth started before it's too late! 😁 And of course, many thanks to Bismuth!

I love this series, and i love shiny teeth

sometimes it doesn't crash, but sometimes it sure does

Some worlds are kinda weird and there’s also horrifying crashes. Like the 9-1 crash, or the underground segment with dark blue and green lines

Long time 1 hour fan thank you for all the memories

Congratulations Bismuth to your 💯

Hoooooo boy, the series is back

I always laugh so much with glitched worlds, keep it up with all the good content you're putting up!!

Congrats and thank you Bismitu

12:42 hey kosmic! So fun fact, if you wait long enough it actually does count down and you go on to the next level. I tested it in 8-2 with the flagpole screen wrap glitch and it took a little while but eventually a flag pops up and the music plays all the way and the next level starts

Oh, MORE glitch worlds? Yes please! Surprised you didn't try out -2's and stuff. I missed Shiny Teeth!

happy uhhhhh editing anniversary bismuth

we're reaching levels of meme magic never though possible

If a dentist inspects only 1 of those teeth segments, the dentist will get about 3000 times the salary for 500 people

2:49 koopa throwing a hammer confused kosmic so hard it crashed the game

Ever heard of the Real Time Corruptor? I think it's something that might make a good video

1:15 average Mario maker level

Kosmic I was just watching your old Glitched World videos and now you upload this one! I was sad because I though it was over but now there is one more :D

the series is back, lets gooo

I've wondered about generating an image from tiledata, the way I've seen maps made of normal SMB levels, but inputting glitched worlds instead of regular ones.

17:26 "fills me up with spaaaaaaaace"

Just as I'm watching to look back he posts a new one

hell yeah, finally with a new episode with this series

Hello Guys! Here's Why These Worlds Are Glitched: This Happens Because The Game Uses Garbage Data To Put In These Worlds! And As For Why The Minus World And Any Of These Bugged Underground And Water Levels Loop, It's Because The Section Where You Come Out Of The Pipe And Beat The Level Doesn't Exist In The Level, So It Loops It Instead! I Hope You Found My Knowledge Helpful!

I want to see more crazy ones!!! Maybe a game genie that I made up should help. Such as this one: MEGAMN!!!!!!!!!!!!!!!!!!!!!!

If you ever want to play glitched worlds, you gonna want an anti crash code for the corrupt stages, as the new stages, only 6 load, and there’s like 20 total that blank out.

THANK YOU BIS-MUTH 👏🏾 👏🏾 👏🏾👏🏾👏🏾

8:18 LOL i laughed so hard at that part. Great video Kosmic, i love the glitched worlds videos :)

In Russia in 90s we had a bootleg "9999 in 1" cartridge that allowed us to play these glitch levels.

so glad to see more glitched worlds

I completely forgot Bismuth edits your vids. It's quality editing.

me when kosmic uploads another glitched world video: :D me when i realized i therefore missed the stream: :(

so glad this series is continuing.

Let's go Bismuth! And let's go Mario guy with a checkmark that comments on Melee videos!! Nice video, looks like it was a fun stream.

17:26 if you pay attention to the music in the background: "Feels me up with SPACE"

this guy is always showing me new things about this game that i never would have thought about! cool!

7:58 Take me down to the shiny teeth city where the teeth are clean and the koopas are fishy

I remember those bootleg 1000 in 1 game sets solid in the US at one point. One had a repeat section of Super Mario Bros that forced cheats and send you to minus world and other levels in different color palletes and music

Thank you for all the hard work, Bismuth!

Good job, Bismuth!!

Okay run video! Thanks for uploading!

The big crash BRRRRRT of DEATH!

(Note that this is before I finished the video): I have been waiting more than two years for this, and I hope it doesn't disappoint

7:15 Another Teeth Segment!

10:12 ROFL )))))) Oh my god, can't remember when i laughed that hard last time)))

Congrats Bismuth!

Bismuth is in fact a champ. yes

(1:39) That's not exactly right. Normally, stairs and those types of wall do use the same tiles. However, the way level data is stored is as a list of commands that say things like "generate a row of n brick blocks at this position", "generate a pipe here", "generate a tree platform here", etc., and some of those commands generate different tiles depending on the level type. In particular, the commands to generate rows or columns of solid tiles generate different tiles in different level types, but there's also a command to generate ascending staircases (which means each staircase only takes two bytes of level data), and that command always generates the same tiles. (1:29) Another example of this is that each brick-with-powerup has two versions: one with a light-colored line on top for outdoor levels, and another without a line on top for every other level type. The code for generating invisible 1-up blocks has a bug where, after checking if it should generate the block at all (invisible 1-up flag), it jumps to the code for generating a brick with an item, and so if you're not in an outside level, it thinks it has to switch to an alternate version of the invisible 1-up without a line on top, and it gets confused and instead generates a block that does have a line on top. (I _think_ it happens to still be a 1-up block, by coincidence.) (6:51) So that one block is probably supposed to be an invisible 1-up. (8:38) There's also for some reason a command to change the palette, but I think it doesn't take effect until something forces the palette to reload (like getting a fire flower, which changes Mario's palette).
