Insane Secret Worlds in Super Mario Bros! (Glitched Worlds #2)

Part 2 of exploring all of the worlds hidden within the code in Super Mario Bros! Some of the worlds tend to repeat things we've already seen, but there are DEFINITELY some bizarre new findings in this one haha. We've actually only gone through about 1/3 of the worlds at this point, so there are definitely more videos like this to come! Follow me on twitch to catch the next one live :)

[@SpartaYoshi]

I'm actually collaborating with Kosmic to document every single level of the 248 glitched worlds to a spreadsheet containing descriptions of the levels and whether it can be defeated or not, if it's prone to crash or if every single restart is a different outcome

[@SpartaYoshi]

I'm documenting all the levels. About 80% of the unplayable levels always spawn at the very top. You need a code to bypass getting stuck at the top in order to play it. Most go on forever cause they don't contain a flagpole with the triggers to pass onto the next level

[@Danstry]

SpartaYoshi what happens if you just kept going? wouldn’t the game crash eventually

[@SpartaYoshi]

@@Danstry either you're stuck in an infinite corridor until time runs out or until the game loads an unused broken object that crashes it. Some levels even have different outcomes like E-1 cause it's loading code that gets modified on real-time

[@SomeGuy712x]

(5:07) Strangely, midpoints in these abnormal world levels may not be where you expect. For instance, the midpoint in the traditional world -1 that we all know and "love" is in the first pit, so you fall and die right after spawning there if you don't start swimming immediately. (5:51) For some reason, world 5-1 usually appears right after you get three pipe-entering cutscenes in a row. (6:11) Welp, spawned in a sky bonus room that has no time limit assigned to it, so you die instantly from time up, and even if you didn't die, that would've been the end of the line for this world anyway. (7:21) D'oh, I hate this teaser of a level. You got these castle corridors with a red background, along with a Buzzy below. Looks like it could be something interesting to explore, but you spawn up on the roof in a softlocked state... (7:45) Same deal with this teaser world, and not even that Bullet Bill can free Mario from the softlock. (8:40) Ooh, this one's different, though you need a midair jump/swim code to avoid falling into the pit at the start. (8:48) Welp, this was a short level... or is it? (8:57) If you had grabbed that flagpole, Mario's auto-walk would've taken him into the pit right there, and the death music would start to play, but then every couple seconds, the game would "buzz", play the first few notes of the level clear music, and lurch the screen forward a bit. If you keep waiting for several minutes when it starts doing that, then eventually the level clear music will play out in full, and the screen will scroll to the right smoothly. Several more minutes later, Mario will reappear at the top of the screen. If he then falls into another pit, this will repeat. On the other hand, it might theoretically be possible for Mario to land where he'll enter a castle and trigger the level to end properly. However, more than likely, this is a softlock situation. (9:38) Welp, grabbing the flagpole there caused an instant softlock, due to the wall on the left dislodging Mario's grip on the pole early. (10:17) And, this is what I just described in my paragraph above. (11:25) I have no idea what killed you there. An invisible enemy sprite? (14:06) Ooh, another interesting-looking level... which turns out to be an evil tease, as the game puts you in "cutscene" mode, where you automatically walk to the right slowly. This is a softlock if you bump into any object that's not an enterable horizontal pipe. (14:13) LOL! I didn't know you could get hammered in this "cutscene" mode! (14:17) But, since this is apparently a sky-theme area, and you didn't die from time up, you respawn at the top of the level without losing a life, and since there's a roof, you're instantly softlocked. (14:57) Yeah, money! (15:02) Ooh, this is interesting, hitting a right-moving platform while in "cutscene" mode. (15:38) Weird. Maybe that Fire Bar had the size of a large one, despite looking small. Well, that's unfortunate. I doubt you're getting past that, unless you get to this level big and don't get hammered by Bowser at the start. (15:55) Argh, another teaser world. So frustrating that you can't explore these due to the roof spawn softlock. (16:20) Heh, black box-1 = a black box. Who'd've thunk? (18:38) "I have to go now. My planet needs me." (19:04) Aw, nuts. A game crash. (20:11-20:20) LOL, that fire bar Kaizo trap. But, maybe if you had very little time left when you hit the flagpole... (20:25) Wow, what a convenient midpoint! (20:47-20:54) Success! (22:18) If you didn't have walk-through-walls, this would've been a softlock here. (22:24) And, down you go, since you weren't riding a boost platform this time. (23:15) I've seen that kind of thing myself before. Usually, you can jump on it and it'll turn into a normal Koopa, as if you had removed a Parakoopa's wings. (23:26) Yet another "cutscene" level... (23:46) To infinity, and beyond! (24:08) Welp, this brick world apparently bricked the game.

You didn't found the Bowser page wrap glitch. When I was a kid I used bootleg consoles and shaking cartridges caused crashes. So does shorting the cartridge pins.

In underwater 8-2 and underwater 1-1: the smb1 level format is not a bitmap. It's primitives and entities. The stairs are one primitive that has length parameter. The walls have y parameter. In underwater level mode stairs are rendered as chocolates. Walls are rendered via floor tiles. You can find level editor to play with it to learn the entities in smb1 and the level scenery format.

The effect you're seeing is something like overflow words. You had boundaries over the memory schema for the game. This means that you have certain areas for desired purposes, like layout maps, characters and things like that. Those codes bloke the game code allowing you to access words that it's just chunks of memory used for other purposes than drawing maps.

[@FewVidsJustComments]

The reason why the flagpole in the brick world doesn’t end the stage properly was because here’s no castle to walk into, so he just keeps walking until he reaches one, which of course, nether happens.

This reminds me of when I would use GameShark on GBA and to a lesser extent, NES to N64. I would mod Pokemon early gens and many other games to make all sorts of crazy stuff happen, really testing the limits of what you can do by editing the values going from all the range of values like you did. Never seen someone do that to this extent on KZbin, subscribed. This was always really fun for me after beating a game I liked to start hacking into it with GameShark

'Right side of top of a hill - 8', cracked me up

[@elaynet382]

24:00 It actually makes perfect sense through the eyes of an 8-bit game designer in the 1980's. They had a limited amount of colors to work with on each tile and sprite, but there's always a special "transparent" color that lets the background show through. So, as long as you can always ensure that the background is the intended color and nothing else is going to draw behind the sprite, you can use the transparent color as a bonus color that happens to be the same color as the background. The reason it looks odd here is you've loaded the axe in a level with a blue background which is never intended or possible under normal circumstances.

a funnier way of covering this is to use the two-liner code YILLPO + VTLLAO, which randomizes the level you go to (most of which are outside of worlds 1-8) whenever you die or complete the stage (excluding castle stages which softlock the game, dying still works, though)

Fun fact: given that there are 256 possible worlds in SMB (only 8 aren't glitched), and 256 levels in each world (only 4 aren't glitches, in each world), then there are 65536 possible levels in Mario. Only 32 of those aren't glitches. That means 99.95% of the levels in Mario are glitch levels. You only play 0.05% of the levels there are...

[@dexterhaxxor]

That is not even close to how it works.
