Official Lost Levels of Super Mario 3

[@itsgruz]

You know what's crazy? These lost levels were ALSO hidden in Super Mario Bros All-Stars on SNES! WTF?!

[@SoulcatcherLucario]

the nes and snes use pretty much the same cpu (both are 6502 derivatives and they're programmed identically), so they probably used the same game code, which has the same unused levels, and just changed the code to make the graphics work on the snes.

[@nensondubois]

Very true.

[@onvogmasaj]

video or it didnt happen

[@mchenrynick]

Could you add the Game Genie codes for each hidden level into the video's description? Some of us would like to try these on real hardware. Thanks.

[@randomguyontheinternet7940]

They were probably planned to be included add a bonus feature. Which... yeah no shit.

[@merrimac290]

It's over 30 years since this game's release and I'm still learning more and more about it.

[@IkeruOZ]

Dear Gruz: Time ago, making a rom hack of SMB3, I found that there are more left-behind levels! I found them in the map's yellow dots. Some levels were impossible to play becouse of glitchy items, but other levels were playable! So, I am making another rom hack that presents all these levels. Wish me good luck! Yours truly, IkeruOZ. Edit: I'm putting some goal cards an changing the spawn in some levels.

[@Metalwario64]

Here's an interesting observation about that starry sky in level 14 from looking at pre-release screenshots on TCRF: there exists a beta screenshot showing a coin heaven with a sky gradient effect where the sky gradually gets darker. Those star tiles surely would have been used if that effect had remained in the game.

[@psirensongs]

The idea of a vertically ascending stage where the sky gradually gets darker as you go above the clouds is actually brilliant

[@TeamRocketHQR]

Nintendo wanted to do a lot more with the Super Mario Bros games that most know about too. Like even a 3d like thing with the original Super Mario Bros. That ground you run on all the time? Notice it's a stack of two of the same block. The goombas/troopas can actually walk on that bottom layer. They just walk on top of it inbetween the two. It's a bit of a leftover of the 3d thing they wanted to try. Look up design doucments on this too. It will explain it more. SMB3 was actually finished in 1988 and we didn't get it in usa till 1990 too. Like you said there's a bunch of things they wanted to do with this too. There's some unused castle icons for the map too. And a beta screen of the world 1 map that had a bit different path to the first fortress too.

[@Vulpas]

Kiribo’s shoe was tragically underused in the game, it was insane just using it for one level. It should have had one stage in every kingdom.

[@AtKiba]

These are indeed debug levels, fun fact, one of these levels was featured in the box of the game. I always wondered as a kid how to get to that level. Edit: I stand corrected haha, that level isn't even among these 15 hidden levels

[@NoSpin23]

Oh I had that same box and remember telling my friends "dude, this level is not in the game, I've beat it a hundred times!" They all thought I was crazy LMAO

[@AtKiba]

[@cujoedaman]

I always felt there was something off about some levels, especially the map screens, there are a number of areas that looked like you were supposed to go to more places and with things like bridges and being able to break obstacles that didn't really get you any place special, they must have had a lot more planned.

[@dr.decker3623]

they did,.. and it all went into the sequel, Super Mario World.

[@IvyANguyen]

Remember near the end of World 2 (Desert) when you break the rock to extend the map eastwards there was a body of water shaped like Roman numeral III?

[@GlobalWarmingSkeptic]

The real reason they leave the levels in the game and why many resources are left in the game is because when any kind of project gets late in development, there are lots of references to that level data, and without being too technical, a failure to find all of the references to the data could result in bugs and crashes that are hard to debug.

[@theperfectbalance5482]

The real reason is work hoursm im not going to pay gou to remove what doesnt even matter kid. U get your 40 hours and thats it........ 😒🙄🙄

[@DavidWonn]

6:25 I found this level on my NES back in the 90s *without* a Game Genie. You need an original style NES, partially eject the game just enough so that it doesn’t cause the infamous blinking power light indicator on the console. If you’re very lucky, the game may start Mario on the World 1 map, but he will spawn off-screen to the upper left part. If pressing the A button doesn’t start, keep moving in random directions until you hear Mario move. Then press A. If you’re even more lucky, you just might get the game to start at this particular hidden stage. Good luck!

[@rodrigodefreitasproducoes1338]

Cool!

[@azuraltumbabic4239]

If i get a nes with smb3 ill try this and if it dose not work, i just have to question my self why your lying. Also where did you know that the level you "Found" was unused? Like no one has that good of a memory!

[@psirensongs]

@@azuraltumbabic4239 You've never seen or heard something after several years and realized you remember it from your childhood? I'm not necessarily saying I believe that account 100% but that's like the most believeable part lol. Cartridge tilting or damaged pins can have some really interesting effects on games and there's no good way to simulate the effects in emulation. As an example, I wish I still had my original copy of Maximum Carnage for the SNES because it was spectacularly busted and would occasionally fail to load cutscenes or scripted sections at the correct time, which would sometimes lead to me losing multiple lives during a "cutscene" (where the widescreen bars appear on screen to transition from gameplay to cutscene, and you lose control of your character), or sometimes allow me to continue a boss fight when I shouldn't be able to for another 10-20 seconds. I've haven't been able to do anything like it since. Being able to access something in memory by accident- especially when you're a kid and you have no idea how, why, or how video games even work, and ESPECIALLY on a system as temperamental as the NES- isn't that hard of a sell to me. That seems like the kind of thing that would stick with you. I was 9 or 10 when I did all that shit with Maximum Carnage and had owned the game for years before it started acting up. I remember it pretty vividly. Maybe I'm just gullible.

[@Faber0k]

@@psirensongs not related really, but I remember when I was 10 (23 years ago) I pulled my link to the past cart out without hitting the eject button, and I broke the cart in half. I taped it with electrical tape and it still works to this day.

[@psirensongs]

@@Faber0k That's awesome lol. I had a similar "How tf do you still work" copy of NBA Jam. Somebody (not me!) threw it at a wall and exploded the entire corner- about a fifth of the cart. We put it back in the machine and it worked just fine. Unfortunately, I don't still own it, as my parents eventually sold our SNES, but I remember it still worked for the remainder of the time we owned it. I've always marveled at how seemingly invincible old cartridge games are.

[@FnrrfYgmSchnish]

It's still *super* weird to me that the "swimming up dark waterfalls with wooden blocks" level exists. I had a dream about a level that started out with a section exactly like that, waaaay back in 1991 or so when I was a little kid playing through SMB3 for the first time.

[@DeFameWRONGCROWD]

I had the same exact dream

[@DeFameWRONGCROWD]

But for Mario 2

[@lukewarmwaterr]

I had a dream (or more aptly a nightmare) when I was playing Mario 64 on the Wii VC. I was trapped in some sprawling dark area that I couldn't leave even if I paused the game and exited the stage

[@fernandolomas6635]

I once had a dream that Mario Kart Wii had entirely different characters and vehicles and that each vehicle had at least 2 or 3 characters in it

[@yopachi]

Loved seeing behind the scenes WIP stages. Interesting to realize that they designed these levels with a mouse.

[@planchetflaw]

Pretty sure every member of Nintendo were humans.

[@drowningin]

I thought they were designed in a notepad with characters being what spawned. How can you tell it was a mouse? I actually remember an interview where they said the levels were designed in text file, but that might of just been the first

I like to think that Levels 11, 12 and 13 was the level designer not really knowing how adding levels worked so they did it several times)

[@hurktang]

no, i'm pretty sure they were mushroom levels like 1-3 in the original game. Early in dev, someone must have discovered that you can save a few tiles in memory by cutting the lower part. And then someone else in the back had a strike a genius. "you know what would take even less tile in the code ?" "no mushroom at all!". They replaced the mushroom blocks by wood blocks which were easier to rotate and the only level which survived this era was 1-6.

I always did feel like Level 5 was underwhelming in the whole Sky World build-up...now it just appears it's because half the concepts were never finished.

[@duffman18]

I always think of the E-reader card levels on the GBA version of the game as the lost levels of SMB 3. Because basically nobody has an e-reader or those cards. And there's like 100 of these new extra levels. These days you can easily Google for a romhack of the GBA SMB 3 rom that adds in all the e-reader levels for you, and simply play that. They're a lot of fun. They combine powerups and level styles from all the 2D mario games. So you'll be playing Mario 3, but while wearing a cape feather from super Mario World, while pulling out vegetables from the ground like in super Mario bros 2. Stuff like that. And they're official Nintendo-made levels. Honestly that's my favourite version of SMB 3 nowadays. Because of the dozens of extra e-reader levels. And it's very easy to get the romhack that adds in those extra levels so you can play it on an emulator or even chuck it onto an everdrive and play on a real GBA

[@michaelhockaday6474]

100 is quite the exaggeration. Lol. There are exactly 38 e-reader levels.

[@StevenVillman]

*@duffman18* The "Final Airship" e-Reader stages/levels (these stages/levels consist of King Bowser Koopa's personal airship, which was so huge in size that it occupied *_MULTIPLE -_*_ _*_*2*_*_ _*_- AIRSHIP_* stages/levels, where you have to fight him in a boss fight at the end of the second airship stage/level inside an airship cabin!!) were my absolute favourite e-Reader stages/levels!!! (I've seen video game gameplay videos of each of them on KZbin.) However, sadly, they were only officially available in Japan (until the _Super Mario Bros. All-Star_ video game title, which has the 16-bit version of the _Super Mario Bros. 3_ video game in it, was released on the Nintendo Wii U Virtual Console); so I wasn't able to play them, *_myself,_* to this very day (I never owned a Nintendo Wii U, nor did I ever live in Japan).

[@the6ig6adwolf]

Couldn't agree more 👍

[@KingOfApoc]

There is an exit on level 11/12. On that green island thing at the end there is a hidden coin heaven block that takes you to the end

[@SuperNickid]

@ Frank M: That only appear in a fan made Super mario bros.3 game where he modified it himself to have an exit so you can progress through the game, and also he went all bunkers with it, and show an unused graphic of the same lost levels, so the real one does not have it. I don't remember the name of the fan game, and i don't know if he as a patch of that fan made game, in the website rom hack because rom no longer exist, so you would need the non-modified version of the rom and a lunar patching software, make sure to make a copy of the original rom so you don't lose it.

[@KarlBonner1982]

I remember some screenshots affiliated with the McDonald's Happy Meal promo, that clearly showed two levels not in the game. One was a floating cloud level with lots of parabeetles, the other was grassy like 1-2. In both instances there was no level display at the bottom of the screen, just "MARIO x4" or similar.

[@goody1701d]

The levels were left in because they don't really take up much room because they are only calling up existing sprites for the most part, the code doesn't take up much space, and it was easier to just leave them in there than hunting down and deleting the code

[@legoboy7107]

12:41 You actually can jump high enough to make it on top of those question blocks, you just need a running start and P-speed, because in SMB3 P-speed makes you jump 6 blocks high instead of the usual 5 (this is not true of the SMB3 style in Mario Maker though).

[@pentelegomenon1175]

Some of these are great concepts that would have really elevated the game. I wonder if they got so good at making levels by the end that they had to stop themselves or they'd never finish the game, and these levels are just a snapshot of that moment. And maybe instead of stopping altogether, they just switched over to working on Super Mario World, the pipes going up and down reminds me of some things in that game.

[@bland9876]

The Wii u virtual console version of super Mario advanced 4 super Mario Brothers 3 has an entire section of levels that have to select on the main menu. They are very cool.

sure it left japan. that version was ported to a number of Nintendo consoles in the time since NES. even on the wiki page it says " The game was renamed The Lost Levels and first released internationally in the 1993 Super Nintendo Entertainment System compilation Super Mario All-Stars. It was ported to the Game Boy Color, Game Boy Advance, Wii, Nintendo 3DS, Wii U and Nintendo Switch."

The Shoemba. That's a good name for the shoe goomba....

[@BrainSlugs83]

Most of these just look like early prototype versions of actual levels and building blocks. Some of the physics might not be useful for the levels because they were probably experimenting with different features and not all of them made it into the shipped game.

[@redsquirrelftw]

Stuff like this is so interesting to me. The way these old games were coded was very different than today and it's neat the weird easter eggs and oddball stuff one can find when they dig into the rom. Would be cool if Nintendo re-released these old games but with a whole new world/levels, but same game mechanics. The format just has unlimited potential.

Did you know that the world map featured on the SMB3 card board box what different then the world map 1 released on the cartridge. There was also a grass level display with tons of parabeetles that was also not in the released game.

[@costby1105]

These level most likely were dummied out for quality, pacing, being unfinished or just being test levels. The reason why they would still be on the cartridge is pretty simple if they removed them it could cause issues with the coding on the final product so instead the devs on old games just made cut and unfinished content unreachable.

[@magyaradam8957]

Amazing video. Mario 3 missing levels were always a mystery as a kid.

[@exidy-yt]

Very cool! I am betting they had so much room to leave unfinished data because back in those days there was no way to add a small amount of more space, you pretty much had to double it with adding a second identical chip. This left far more room then was needed to complete SM3, so they didnt need to clear out the unfinished areas to make room for final touches before burning the final ROMs. And regarding the lost levels on SMBAS on the SNES, again that's no surprise as they used the inital code for the game, just updating the textures. (plese forgive me qany lapses, as I am a big liquored)

[@nick56677]

Personally I think all levels started out like this, it's just that some levels got finished (expanded and tweaked until they were officially accepted) while others were abandoned at some point as the concept was not working very well or there were technical difficulties or they weren't required anymore as the game already had enough levels. There may have been even more unused levels but they maybe got deleted once their space was needed while these few got left over as their space wasn't required.

Aww yeah bub. I love your style and channel. Smb3 is my favorite Mario, because nostalgia, next to sunshine/odyssey. Too hard to pick
