Exploring Minus Worlds in Super Mario Games! 

<a href="#" class="seekto" data-time="425">7:05</a> 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.

gruz, your calm and heartfelt "Goodbye" at the end of each video is one of the most wholesome things on the internet.

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

it's not a secret anymore

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

I've never heard a better impression of the Angry Video Game Nerd than <a href="#" class="seekto" data-time="400">6:40</a> . You sound just like him!

Thank you for pointing out that it's not world "minus one" but actually a misread undisplayable character

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 😢

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.

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.

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.

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.

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)

whats about Super Mario Bros. Special ?

That was fun. Can't wait to try these out

Been loving your videos for some time now - they have such a high production feeling to them! Like they came from a big studio! Bravo man - keep it UP!

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.

I've been waiting for this video for decades.

Nice, a new video! I really like this, wish you either did long form content or more frequent videos, they're perfect for binging.

I love that Japenese re-release one! Thanks for sharing this, love these kinds of videos. Feels so mysterious, like the secrets in Shadowgate or Uninvited. Even though it's just basically memory errors, the results are fascinating.

Super cool my bro! Loved it! You are crushing epic retro nes!

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

Gruz i love your vids man, and i love how you keep coming back to the first Super Mario Bros. game and show some weird shit with your fun naration. Never stop.

YAY! I've been waiting for my next dose of Gruz! :D

Great video as always Gruz! Thanks

Great video man, thanks for the upload!

Does it work on the Atari?

Oh, I was always curious about the VS version, so dissapointed to see it's just the same old samold

great video!! also what a coincidence I found this, I just started researching stuff about the first smb game the other day, and it was only yesterday I learned about the minus worlds at all haha!

Why does this feels like the super mario bros. version of the myth of "every mario 64 copy is personalized"

I remember part of the advertising for the GBA version being that the minus world glitch worked.

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?

I love these videos. I gotta try all these Glitches out

this video was so lovely! It's like the wholesome avgn, he even sounds like rolfe

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!

The GSXCC mix at the beginning really brings me back.

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.

Gruz. I absolutely love your videos

Great Content, Super Mario Bros for NES was the first time I played an NES game. I was at my uncles house and he just bought an NES back in the late 80's. 👍🏻🇺🇲

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.

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.

<a href="#" class="seekto" data-time="86">1:26</a> - 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?

Thank you! That is very interesting!

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

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.

And Mario rescues no-one. No one lives in the Minus World.

another great video my man.

<a href="#" class="seekto" data-time="196">3:16</a> 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

Nippon: Nippon Gruz: niPOWN

Joke: The person who rounded up loads of animals on a boat? I hardly Noah!

Gruz videos on Super Mario Bros never disappoint!

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.

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.

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.

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

Perhaps finding a Genesis version of VZTLTN to shut off the timer to go through the stage, but it being a cloud level it’ll just… 1. Falling loops to the beginning 2. It never ends

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.

That's pretty cool the VS. arcade version has it

<a href="#" class="seekto" data-time="194">3:14</a> 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.

Cool Video!

World Bitcoin-2 wasn't 1-1 with Piranha Plants. It was JUST 1-1. Any level that ISN'T 1-1 will have Piranha Plants, so since its numerical world isn't 1-1, despite being otherwise identical, world Bitcoin-2 has Piranh- NOOO FLUXIE31 BEAT ME TO IT <a href="#" class="seekto" data-time="539">8:59</a> Heaven Zone Act 1 (Mario dies because it is the afterlife)

I used to do that glitch and the being small and throw fireballs glitch!!!❤❤❤

My romhack SMB Extended removed the minus world completely despite extended worlds and non-duplicate levels such as World 5-3.

Theres another port of Super Mario Bros. It's a SNES port but it has the 8 bit graphics, that minus world is underwater 4-2, you forgot that one

I had a PC Engine when I was a kid. It was the only ROM module based console I ever personally possessed as a kid.

Minus world also works the same in SMB in the original Animal Crossing on Gamecube.

I enjoyment learneded about various glitch you can do it

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.

There are so many weird things with the minus worlds. I saw someone on here mess with the code to get all sorts of symbol-1 levels.

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

I've been playing this game since 1988. SMB was my first video game ever. All this time and the little quirks and bugs never ceaae to amaze me. Shit, this game really stood the test of time. Its come a long way since us first kids were saving Princess Toadstool from King koopa than eating our Nintendo power cereal for breakfast than Swapping game and watches during lunch.

And where does that leave the Underwhere?

I have a suggestion for this idea! What about exploring possible minus worlds on mario romhacks? They have rearranged memory, so each result should be different.

Does it work in Super Mario Bros. Special too? Edit: just remembered they removed the warp pipes in this version

plus zone warps peach into daisy

How come you changed your username from killgruz to itsgruz? Is RU-vid forcing others to remove such words from usernames too?

FINALLY

Man i really wish the trips you did in your older videos, they were always so weird and suprisingly that the videos really stuck

Hmm, I wasn't aware of the TG-16 version, and didn't know much about the Genesis version. There is a ZX Spectrum version and an Atari 2600 version. I don't know if there's anything else it got unofficially ported to. Probably there is.

Did you also know that in super paper mario the underworld is also called world -1.

<a href="#" class="seekto" data-time="213">3:33</a> you can clip into the pipe without any hacks

I always thought they should make a game with all the minus worlds but beatable

Is there a minus world in SMB Special for PC-88 or Sharp X1? Always found these versions interesting because they were official sequels but only for those two Japanese PCs and were made by Hudson and Nintendo as a joint effort

new gruz video!

Gruz I'm almost 100% positive I literally just saw you at the SF Costco 🤔 didn't want to say anything because you were with family!

I recommend checking out the bootlegs of the multicarts (100 in 1) where it has several pages repeat of like 10, 20 games. But some have added cheats or you start in a different level One bootleg I still have is Super joy 3

If you do a sequel to this video could you possibly try the minus world trick on the game and watch

In the flash version "super mario crossover" you can complete the minus worlds.

Good vid. Idea: Minus Worlds in other marios (not smb1 or remasters but like smb2) (YES IT'S POSSIBLE)

I was like why does this voice sound familiar? It's the classic mac gaming guy!

The non water levels can be accessed by tennis cart swap trick works on toaster top n top loader and takes you to every glitched level in game 255 in total maybe more

What about the other bootleg Genesis port, the one with All Stars level graphics and Sonic player sprites for some reason? Where does the minus world pipe in that one go?

We need a mario minus verse 😂. Cool range

What about the NES compilation copies (Mario + Duck hunt) or the Nintendo World Championship copies

<a href="#" class="seekto" data-time="541">9:01</a> DID HE JUST DR SEUSS IT🗣️🗣️🗣️🗣️🗣️🗣️🔥🔥🔥🔥🔥🔥🔥

Hey gruz can you play super ale bros redux? It changes the entire game engine making you go backwards and having on and off switches. Making it play like mario maker

It actually world 36-1 but the tile for 36 was blank

in Super Mario Bros Special is possible to do this trick?

I can’t believe they got All Night Nippon on his taxes
