It's because these levels are essentially the unborn abominations of the game. They were never meant to see the light of day. The inhabiting enemies don't know what freedom is, or even visitors. Their existence was a mistake. Their God, knowing this, did not kill them, and instead hid them away for the rest of eternity.

[@Pinkio]

curiously, when you try to edit the ROM of the original Mario game, there's like 3 invisible objects named "*Crash" that practically are only used to crash the game if one of them appears on screen i guess the minus worlds somehow ended up placing these over them nad that's why they *crash*

It's actually what happens when you touch flag pole, time goes to zero (in this case the time is already zero), Mario walks right, than he walks into a brick camouflaged in front of the castle, than the level transitions to the next level (which in this case, Minus World's level layout is complicated), if you removed the brick, Mario would walk forever, and die, unless you turn off the timer, where the game gets confused and loads random assets, which results in insane things. That's why if you jump over the flag pole, you start walking walking forever.

[@dusaprukiyathan1613]

Charlie P I don't think you've got that right. What actually seems to be happening is similar to the start of 1-2. Mario slowly walks forward and enters a pipe to go underground. Except in this case there is no pipe.

[@fqiryal]

i would say by code, but i’m far off from that lmao

[@netawa]

I didnt dig into Mario code too deep yet but here is a generalization of what is "likely" happening because we are talking about ram mixing. Each object in code has a set of pointers, special commands which show game what to load for this case. Judging from results, this point is likely a single big string of symbols and on minus levels it gets kinda of randomized. Game attempts to read this string and load assets it points to. Assets being levels, colors (I would say textures but judging from orange pipes, I assume even colors are coded different) and motion type. Since UI and Mario are separate from world loading script, they are mostly unaffected. So what we get is - random mix of level structure loaded on top with random textures/colors loaded. What I find interesting is that it doesnt seem to load only one skeleton of the level but rather it loads several and put them together. (That's the part where my lack of knowledge of SMB shows, I am sure that this level mixing is explainable with something like slices) Well, that was not too good or even in time answer but it is what keeps me curious too

@@JoelHernandez-tz3vk not entirely arbitrary, it's the games normal logic, just fuzzed up a bit. Imagine trying to read a book where every letter has shifted by one and someone is trying to make you explain it

[@JoelHernandez-tz3vk]

@@jacobmassengill3360 I imagine this is probably true for most level where the one shifted letter happens to be that one that governs the level's tile set, seeing that most of the levels shown are usually the normally accessible levels but with the tile set changed. The ones labeled "Corrupt" look a LOT more arbitrarily generated however. I can only wonder how arbitrary it is in the "Corrupt" levels. Maybe is also a single letter being changed but that letter was somehow the seed needed for level generation, but here I'm assuming the level is procedurally generated

[@cattharsis]

I think the reason most of these worlds are underwater is because when the CPU tries to look into memory for the Minus Worlds, it goes below the actual limits of the array, thus accessing memory that contains literally anything else. Due to that, the data it receives is mostly unusable as a level (and I guess mostly as blocks due to the fact that it's attempting to read those values as blocks and/or entities), and within it, the flag for underwater gets set somewhere (haven't looked up at detailed breakdowns of the level's data structure)Either way, I think it's curious to see how the game engine parses the data into a level that looks like stuff thrown out of a toybox

[@alessandroceloria]

Mostly - there are just a few types of level (normal, underground, castle, water...) but 256 possibile values for the "Level type" field within each level structure. To reduce the chance of crashing, nintendo filled all the "empty" level types with the type associated to the water level (for no particular reason, they could have choosen any level type, they just happened to choose the water one), because if the game tried to access a null value it would have crashed. So, since all array entries have the water type except for a few (the other "ground" level types) there is a very slim chance of minus levels to be anything but water. As far as the level structure is concerned, yes, most of the times it reads out of the level memory and displays garbage, resulting in a crash... But some times it tries to read actual levels, but since the Level metadata for world 36 does not exist and is still random data, when loading the level some basic structures such as the color palette, the terrain and enemy tables will be swapped out, resulting in wrong enemies, shifted colors and wrong tiles... That's how the variants are "created"! Sorry for the looooooooooong replies but i love these kind of things and you see ed interested too 😁 TLDR Yes, the game indeed tries to interpet random data as level layout resulting in levels really close to Mario maker creations

[@shorthouse06]

@@alessandroceloria "null" is just a programming language abstraction, there is no such thing at the binary / assembly level. An assembly function can't crash, it will just read whatever you tell it to, even if it's complete junk. The game is just reading random data from memory and interpreting it as if it were a valid level. The game probably uses a single bit that's set to say 1 for water and 0 for normal, and it just so happens that the data past the valid levels has a lot of water bits.

Thanks so much, and keep up your great work :)

[@letcreate123]

If I recall correctly, only with the Famicom version (*not* Famicom Disk System) can you access some of the glitch levels without hacks or cheat codes, and it requires doing a hot swap with Tennis to carry over the RAM values from that game to SMB1, and even then you have no control over which level you're gonna get. This can't be done with the FDS version because of how the hardware works.

[@PolarHacker]

@@letcreate123 I forgot about the Tennis trick. I read about it before, but never tried it myself. I've heard that it works on a standard NES too, and the the number of steps you take in Tennis results in what world you get. Again, never tried it, so I can't confirm if that's true or not. However, the Famicom Disk System version is special because not only are the minus worlds completely different, but you can beat levels -1, -2, and -3. -3 is a castle level and so after completion you simply return to the title screen. Interestingly, when you complete that level the game registers you beating the game, so it's an easy way to access the hard mode and world select. As you mentioned though, the Tennis trick probably wouldn't work due to it using disks, but I wouldn't mind seeing a video of someone, *cough* Skelux *cough*, hacking it to see what other hidden minus worlds there are.

Something weird about World. S-2 is Mario literally dies before the timer even gets a chance to show the number.

[@TheBetterGamer]

I want someone to compile all the playable/winnable levels into one game tbh. If need-be, take out water in some levels and add more enemies? Super Mario AntiWorld!

[@607]

TheBetterGamer How do you mean, 'take out water'? Just revert them to the original levels?...

[@TheBetterGamer]

@@607 no, "take out water" means "take out water". aka, mario moves like he does in overworld and not swimming.

[@607]

TheBetterGamer Ah, okay. So underwater tileset and music with normal physics. Could be interesting, I guess.

I actually have a pretty old bootleg cartridge (one of those 9999999 in 1 kind of stuff) that has all of those minus world included as separate super mario bros. games that you can choose from menu. I've been messing around with them a lot as a kid but didn't know why they're like this. I even wanted to record it when I got more into secret game stuff and corruptions and shit but I don't really have anything to record that with. The fun thing is, those worlds are kinda different each time you load them, like enemy or other actors spawns. You can even get bowser to get stuck in the floor/ceiling or fire spawn at random places and kill mario as he walks into the cutscene like that goomba, it's really fun to browse through the different results :) Anyways, thanks so much for showing all this, brought up good memories and now I am finally 100% sure and those are actually minus worlds! Great video

World T1 has that pipe that obstructs you from going any further. Back in the early 90s, with the help of game genie, I had a six letter code that I discovered that let you pass through all pipes in the game as if they weren’t even there! I don’t remember exactly what is on the other side of that pipe, but I can tell you for a fact I didn’t make it much past it.

From what we can see, I think a little part of these level are made for testing purposes, and the water theme is default one since most of corrupted level have water.

I didn't know about the other 245 minus worlds. I only knew about minus worlds -1 -2 -3.

[@sonicblast19]

I had a famiclone as a kid and had most of those levels in the 99999999 menu. It was so wonderful imagining what could have been after those levels that unfortunately couldn't be passed. Also for 9-1 I did manage to beat it on the system and it happened once every blue moon and 9-2 is just one of those underwater boss sections that can't be beaten.

[@sophiegrey9576]

What about on the famicom version? Aren't the levels different?

Super Mario Bros. - Minus World - Famicom Disk System Style type or copy and paste that into the youtube search

[@BuddyPlot]

I may not be right, but there are actually 34,359,738,329 minus levels to play in minus world. In the hex, there are 4 hex codes that make up a level. For example, World 1-1 is "90 A6 01 9F", the 5th hex doesn't matter Each hex has 256 combinations of course, so 4 hexes would have 4,294,967,296 combinations. That's a lot, but we can't forget about the backgrounds and physics. There are 4 backgrounds (overworld, cave, underwater, castle), and 2 physics (gravity, swimming). Add that up and you get a total of 34,359,738,368 levels! If each level lasted one minute, it would take you 65,372.41 years to go through all (surprisingly not that high. Get a team) We can't forget about hidden levels, since they aren't in minus world. There are 4 coin heavens, 1 warp zone, and 1 coin underground (I checked, and all coin undergrounds were all clumped to one level, fun fact), don't forget the tunnel pre level. Subtract that, and you get your answer

I played a lot of those in my childhood. I had a Famiclone with SMB built in, so if I were to twist a cartridge, it would send me to these levels depending on the angle. I remember having hours of fun discovering these.

[@luisbordones691]

Skelux Super mario bros Lost levels has minus worlds too?

[@celiaalomia4305]

No, but World 9 (especially the first two) is similar to it.

[@brawlfan]

I think I remember hearing something about underwater flagpoles softlocking the game under specific circumstances. Maybe if someone else tried, the minus world ones would lead to another level? I think I remember someone putting a flag in the section that -1 copies and going to -2. Though of course altering game data could cause the minus levels to be different than they would be without altering.
