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.

Very true.

video or it didnt happen

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.

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

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

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.

@@TeamRocketHQR highly interesting

It actually did: tcrf.net/File:SMB3NES_UnusedGradient.png

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

@@NoSpin23 It drove me crazy when I noticed the level was nowhere to be found xD specially because it looked interesting

I got to the level with random Game Genie codes I was making up.

Me too.

Memories

I had the same exact dream

But for Mario 2

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

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

Dude me too!

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

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?

Pretty sure every member of Nintendo were humans.

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

​@@drowningin One of their design tools was a wireless mouse on a large tablet.

@@drowningin “might of”: mushy must mean brain.

I'm pretty sure these levels have been known about for quite awhile. That said, I wouldn't call your comment wrong.

@@Lunar994 ok

It's crazy I still have this on my original Nintendo.

Cool!

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!

@@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.

@@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.

@@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.

I never understood why scrapped levels would appear on the box....

@@KingRandor82 For all I know, it could have been scrapped after the box-art was finalized.

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.

@@hurktang Except you can see that all 3 of those levels are basically the same level with only slight differences.

@@legoboy7107 Far more likely these were just early and/or alternate ideas for the same level.

A designer isn’t plural and you don’t like to think.

@@alysdexia What does what you said have to do with the comment?)

Do they still want to come over ?

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

*@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 KZfaq.) 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).

If you buy it on the Wii U you get them all unlocked!

if someone prefers to do it officially by Nintendo. WiiU virtual console of Super mario advance 4 all the e-reader are available including the japan exclusive.

I completely forgot about the e-reader cards. Thanks for sharing!

Right I'm 34 I still have this on my original Nintendo.

Couldn't agree more 👍

@ 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.

Does it do anything?

Same difference; in the Japanese equivalent of the SMB franchise Goombas are called "Kuribos". The US English manual for Super Mario Land on the Game Boy even calls Goombas "Kuribitos" ("little Goombas" or "Goomblings")!

@@MateDrinker33 that means chestnut-something.

Weeb

I've always wondered about that screenshot also, I was disappointed not to find it anywhere as a kid! The screenshot of the World 1 map ALSO found on the same back cover also has some noticeable differences from the final game.

The power up is called Kuribo's Boot.

@@mattrogers6646 "Kuribo" is the original Japanese name for "Goomba", so same difference. My memory is rusty, but I believe the European release also corrects this to "Goomba's shoe".

I think he was referring to the Goomba who has a shoe, not the shoe itself, which is indeed the Goomba Shoe (a correction Nintendo made from "Kuribo shoe").
