7:05 fun fact! Piranha plants are in every pipe (if they can spawn, which isn't always possible cuz of the 5 enemy limit in the game), but they are designed to not spawn if the world is 1-1. It may be a clone of 1-1 but since the world # in memory isn't 1-1, piranha plants spawn in all the pipes in the stage.

[@MrNotSuprized]

oh yea! i’ve heard that before!

[@mario.pinducciu]

I can spawn piranha on 1-1 witout cheat codes! Beat the game, then on start screen press B to switch on world 2,3,4...(not world 1): and wait: on demo mode, mario will play on 1-1 whit piranha plants!!!!

The timer does actually load in that last minus world, but that particular configuration is used for the game's cutscenes. (there's no timer when Mario goes into the underground pipe, because the time is 0.) There's 4 different settings for the timer, in the level header: %00 = 0 seconds %01 = 400 seconds %10 = 300 seconds %11 = 200 seconds

[@AlbertTheGamer-gk7sn]

Well, in that case, Marionaire dubbed entering a level with 0 seconds on the clock and dying upon arrival as "getting T'd up".

[@garrynewman6211]

I don’t know how you guys figure out stuff like this but cool!

[@Icelink256]

@garrynewman6211 Well, in my particular case, I had reverse engineered Super Mario Bros. back in 2016, to help with a game I was developing. So, I have a lot of my notes kicking around, still. I had expanded on the original level format, and added a "relative" block placement mode, to allow for more detailed levels, that use less data. (A relative block uses 1 byte, instead of 2, but has a limited placement range.)

[@JouvaMoufette]

I actually got to play the Genesis port last month and also got to the minus world there! Was happy to see -1 was above ground cause I knew I could get to -2, but sad when it was a cloud level with no timer 😢

[@repoversemedium]

You could say the Genesis/Mega Drive port is 1:1 to the NES original after all.

[@JouvaMoufette]

@@repoversemedium Sorta, but that would be misleading in a few ways. First is that the way you generate sound/music is different, so it sounds way different. Second, while A maps to A and B maps to B for NES vs Genesis controllers, the physical placement of the button is not the same. NES has buttons ordered B, A. Genesis has buttons ordered A, B, C. So run is usually held down by a thumb tip and jump is pressed by the first knuckle. On Genesis port, run is held down by the first knuckle and jump is pressed by the thumb tip. Hard to deal with that muscle memory. Third is that the memory mapping is different, so you end up with a different Minus World on the Genesis port than the NES version. Same/similar code base, different results.

[@anthonyventura9298]

😊😊😊😊

[@eternal221]

even mari0 has a minus world, but i imagine its just an easter egg there given the way the game's coded wouldnt allow for minus worlds to exist their typical way

[@Justin-ul7fh]

Ngl I wanna see what the Mari0 minus world is right. Haven't been able to play Mari0 cause for some reason it won't load on my computer (my computer sucks!!!!!) Then again I've gotten it to play other downloads it couldn't before like 6 months after each time I have a problem with it so I should probably try again

[@Darkoli3939]

There's also the minus world in Super Paper Mario for Nintendo Wii. At least it's a reference to that and part of the story.

[@erics8192]

I remember the days before nintendo power was around and you had to rely on word of mouth at the elementary school lunch table for NES game secrets. According to said sources, the only way to enter the minus world was to jump over the flag pole and go down the top pipe at the end of 1--1.

[@Kawa-oneechan]

Though SMB on GBA is an emulation, SMB-DX on the other hand is a port, since the GBC and NES have quite different processors and SMB was written in 6502 assembly. All-Stars on the gripping hand could reuse vast swathes of 6502 code because the SNES' 65C816 is to the 6502 as a 386 is to a 286.

[@popixel]

The only minus worlds that I think you might have missed are utilizing the tennis pull out method. Granted, those cannot be accessed by using the Mario brothers game alone so I can see why you would skip passed it, but there are quite a few levels that you can access using this method.

[@morganwolf]

Unsure if you’ve seen it, but someone (I think Kosmic) made a video on restoring the Minus levels to the Allstars release (because they didn’t do a great job patching the code)

[@ejsvirtualgarage]

I think Gruz was going for SMB ports only. I am curious about special and the special nes port now.

[@19Szabolcs91]

It doesn't even apply there because SMB Special doesn't even use scrolling. Or warp zones for that matter.

[@shlokwaghela9560]

It's an entirely different game, it uses literally entirely different source code and doesn't do a good job at emulating the original's mechanics

You can also get to the minus world in Mari0 with the same method. If I remember correctly, it's just 7-1, with the exit intact, but the exit just takes you back to the start of the same level.

[@MARKD4WEE3]

In the final, genesis port, when you reach the level of clouds where the timer kills mario, could cheats be enabled to have a 999 clock or time hack; just to further that adventure. This was an excellent vid, had fun watching!

NES: World -1: Welcome to the minus world!: World 7-2: 01/81 FDS: World -1: Minus World: 09/89: Underwater 5-3, World -2: Deja vu?: World 7-3: 27/A7, World -3: Blooper Castle: 44/C4: Underground 4-4 Genesis: World -1: Pipe Land strikes back: World 6-2: 23/A3, World -2: ???: 34/B4: Coin Heavens B that T's you up the moment you enter the level, you will get T'd up until you game over. SNES: Minus World varies based on the frame the Super Mario Bros. minigame spawns due to a TAS in the Super Mario World game. The most commonly used SNES port's Minus World is underwater 4-2 or 1A/9A, but Kosmic's SNES port's Minus World had a -1 world which is world 5-3 or 26/A6, and a -2 world that is similar to the -3 world on the FDS version, with the underground 4-4 and the bloopers. Also, doing the power cycle on your emulator in the SNES port of Super Mario Bros. will pick random tuning areas for the world (16-bit integers), and assign them to the 8-bit areas that normally crash, such as area 49/C9, 4C/CC, 4E/CE, 51/D1, 52/D2, 56/D6, 57/D7, 5A/DA, 5D/DD, 5E/DE, 7D/FD, and 7F/FF. C64: World -1: Minus World: 07/87: Underwater 3-1, World -2: Deja vu?: World 1-1: 25/A5, World -3: Underground Coin Room: 42/C2 VRC6: World -1: Minus World: 08/88: Underwater 1-1, World -2: Deja vu?: World 5-3: 26/A6, World -3: Blooper castle: 43/C3: Underground 1-4 Sunsoft: World -1: Minus World: 10/90: Underwater 6-3, World -2: Deja vu?: World 1-1: 25/A5, World -3: ???: 4F/CF ???: World -1: Minus World: 0A/8A: Underwater 7-3, World -2: Deja vu?: World 2-1: 28/A8, World -3: Blooper and firebar castle: 45/C5: Underground 2-4

[@dimitrijemitojovicic965]

Cool Video!

[@JumboJosh-lv3mo]

There’s actually more minus worlds too! They’re called glitched worlds and are accessed by setting the world value to something beyond 8. This gives you even crazier levels than the PC port. T-1 is my favorite as it is a glitchy cloud level.

[@thebananaspeedruns9275]

3:16 VS Super Mario Bros’s Minus world doesn’t require cheating as there is a speedrun trick where they clip into the top of the pipe and go through the wall completely skipping the need for the bricks, watching any height level any% run to see what I mean

[@edickens8170]

My dad did the minus world trick first try on my Gameboy advance without ever using the Gameboy himself before. He is just that goated.

[@Red-Red-Red-Red]

1:26 - I remember being able to play this version on the original Nintendo release (PAL) back in the 1990s. 3 minus worlds and took me back to the start screen. How was i able to do that without access to Famicon version? Is there a possibility i may have used a Game Genie code?

[@SeanMikhaelObayan]

I like youtubers like this they explore hidden content🔥📈❗️

[@m8rs558]

Entering the middle pipe before its finished loading would take you to world 5. I wonder if they fixed that in All Night Nippon too?

[@theodorfons1551]

Best thing is, you can manipulate the code to enter even more minus stages (by placing a flag pole before the end pipe in -1 for example). You can see even crazier stuff until you enter a fully black room without ground where you instantly fall to death. Actually I wanted to mod this one too but never found the stage reference to this room.

[@mresturk9336]

Rygar and the original Metroid also had minus world type areas. In the case of Rygar there are several. The easiest to reach is accessed by simply jumping off the screen to the left as soon as you enter the final floating island area. The Metroid minus world is a bit trickier to explain. Basically you clip through the ceiling on one of the screens of Ridley's Lair, placing yourself back in Norfair with the wrong map room data being loaded.

[@JustRyzlen]

FINALLY

[@SansTheYtber]

There's also a SNES port of SMB with Super Mario All-Stars music and sound effects. I have tried going into the minus world there, it worked, and it was a different level than the other versions of the game. It is still a water level, however.

[@UltiMaker2]

I remember playing Speed Mario Bros. which is a part of Ultimate NES Remix (3DS). I performed the minus world glitch there and it worked. Exactly the same as the original NES version, but Mario is faster just like in the actual levels.

[@allanmac9292]

The weird symbol you saw next to -1 was actually a black and white coin texture, but smushed.

[@TheMr.L01]

I do wonder if the All Night Nippon version actually fixed it... or just internally confused the warp zone pipe with the exit pipe. (Essentially replacing a glitch with another glitch.) I know speedruns use this kind of glitch in 4-2 and 8-4... would be interesting to check for sure.

World Bitcoin-2 wasn't 1-1 with Piranha Plants. It was JUST 1-1.

[@ioan-lv3oq]

I know a crazier bug . In 2-player mode, if a player dies at the world 5-2 while climbing on the vine, the other one will start his round with a vine top raising from the ground (original version of Super Mario Bros.) If the second player is underwater ,the entities may change (like a mooushroom instead of a fish). The most interestring levels for these are world -1 and world 7-2 after the check point. Please note that this bug is very hard to do.

[@Plazix999]

3:14 actually, smb speed runners have divided a glitch that is humanly possible where you can clip inside of the pipe and run through the wall reaching the minus world without the need of cheats. So that could be used on this game to find out what lies in the minus world but that doesn't really matter because you just went and used cheats anyways.

[@bzsfeelingthebeat]

For those who didn't know yet, there's a game named "Mario Forever Remake (Latest Version: 4.0)" that is a complete remake of the original game "Super Mario Bros 3: Mario Forever". This game includes many levels that you should spend a lot of time finishing all of them, including the minus worlds, as the topic of the video discussed today. Here are the lists of the worlds that you need to finish once you play the game: From the original game, 1. Worlds 1 to 8 2. Hardcore World 1 and 2 3. Human Laboratory World 4. Mario Forever: The Lost Map 5. Funny Tanks? 6. Koopa Troopa Liberation 7. Starman Running 8. Minigame: Mario Minix 9. Secret Levels: Goomba Party and Koopa the Devastator Level New levels added, 1. The Minus Worlds: Worlds -1 to -12 - can be played after finding its secret passages each world. (It will give you a signal that a minus world passage is near.) 2. Worlds 9 to 13 3. The Letter Worlds: Worlds A to Z (sadly it's removed because the developer wants to make this series in a standalone game named Mario Worker: The Letter Worlds Series) 4. World of Tanks 5. Mario Forever: The Lost Map 2 (two versions) 6. The Underground Zone, levels include: a. World U b. The Underland c. The Underworld d. The Underearth e. The Underhell f. The Undermine g. The Underzone 7. The Power-up Laboratory Zone, power-ups include: a. Ice Flower b. Cloud Flower c. Boo Mushroom d. Hammer Suit e. Super Flower f. Propeller Mushroom g. Red Lui h. Goomba's Shoe 8. Remake of SMB World 1 9. More Secret Levels, it includes: a. World 9 (MF 6.0 Version) b. Lakitu Party c. World -7-A d. Human Lab Tower 10. Hardcore World 3 11. The Forest Level

Minus world is a glitch. When you go down the pipe the game reads the tile above the pipe, which has the blank 36 before the numbers appear. Since it reads past the end of the level table the world is glitched out.
