LOCKED Super Mario Brothers 3 Levels...Finally Playable 20 Years Later! 

If you pin this you're in the Koopa Troop 🐢🐢

Point of order: we DID get the e-Reader and these level cards in North America, but not ALL of them. Nearly half never left Japan, making the Wii U release the first legal chance we had to play many of these levels as well.

Super Mario was a big part of my childhood. So much nostalgia.

Perfectly timed video! I just played through the main game on the switch and SMB3 is still the best game of all time imo. This video has inspired me play the E Reader levels. Back in the day I thought the E Reader was the stupidest thing and never even thought about buying one.

There's a hack available of the GBA version with all of the expansion levels already unlocked by default. You and your spouse are quite the dynamic duo! Love the Mortal Kombat scream. Really good stuff from you both. Thank you 😎👍

When I was a kid I grew up in Canada. The neighbour across the road had a father who worked in Japan. I played Super Mario Bros 3 at his house for the first time in the summer of 87' which sounds crazy considering the game didn't even come out in Japan until October. However the reason I am leaving this comment is because the first level of Super Mario Bros 3 was different. The level was the same, only you started on a tall platform and had to jump off it. I remember my friend and I trying to get back up there jumping but couldn't. Crazy right? When I got my copy in the summer of 88' the game was like it was today and I never understood why his was different. I've tried for years to find them online and ask but no success. This video made me think of it.

This was not locked away for 20 years, all of this has been available with the Wii U, a highly underrated System.

She called Doki Doki panic Doki Doki Literature club lmao 10:38

Funny. I am from Dominican Republic, and I got a GBA SP with a copy of the game that surprisingly had the e-Reader compatibility. I just remember how confusing it used to be for me to see that weird "e-World" and not know what it was all about. Surely as you can imagine, e-Reader cards were never for sale in my own country either so that's that.

First, I would like to say how proud I am to support your channel and love love LOVE your content, Lady! As for the locked stages, I am in awe! I never knew about this even back then when I worked and ran Game Stop and now I HAVE to replay this masterpiece as a whole because that means none of us had ever truly beaten SMB3 because we did not play these super secret levels that were locked away! Let the fun begin this weekend tomorrow! I hope everyone here smashes that "LIKE" button and gives our lovely Lady a high five for being super sweet, super awesome, and super entertaining for teaching us something new each and every episode! Sending you and your hubby both a "High Five" because he is also full of awesome and one heck of a great guy who also makes RU-vid a great place to be!

Unfortunately, we here in the U.S. and Canada didn't get all the cards. The most we got were either half of what Japan got or just a handful for the various titles that took advantage of the e-reader.

I completely forgot about these. When I initially clicked on the video, I thought it was going to be about one of the two NES ROM hacks that contained levels not seen in the cartridge release. One that I know will come up in a search is called "Mario Adventure." I only had the first series of cards, so I missed out on a bunch of content.

The well placed Charlie Manson "Nobody" video quote earned my like. WP.

Fun Fact: Doki Doki Literature Club is actually just a reskinned Super Mario Bros. The Lost Levels.

Lady Decade, you’re doing a phenomenal job. Thank YOU for your insights, witty humour, and dedication to video games.

I've got the day off work I've just cooked myself some pancakes and bacon having a coffee and watching fantastic content what better way to spend your day off

A couple of years ago, I have downloaded a saved file from Internet. I managed to copy it to my cartridge using the Retron 5, so I can play it on the regular GBA. 👍

I remember getting some of those e-reader cards back when I first got into Animal Crossing on the GameCube. I even rang Nintendo in my country (Australia) to have some sent out to me (helped that my mother also plays Animal Crossing as I was like 15 at the time lol). I never played the extra levels in M3 though. Awesome video!

Didn't know about any of this, now I'm fangirling for more Mario content. Gonna go turn on the Switch Online and play them right now! Thanks for the share! 😀

Just wanted to jump in and say that I am a recent fan. Looking through a catalog of game reviews throughout RU-vid, I stumbled upon your video of Super Mario 128 and I was instantly hooked. I am a recent subscriber and I have watched several videos since.

Lady Decade: „At least we had Mr. Blobby, and they didn‘t… nightmare fuel!“ LMFAO ❤😂

I had to rewind to check since I wasn't sure how assets from a game released in 2017 could be in a gameboy advance title. Then I realised you meant Doki Doki Panic.

Just to point out that all these new levels were available since Dec 2015 in JP, Jan and March 2016 for US and EU respectfully as it was released on the WiiU. So it only took 13 years and not 20.

I discovered this in the Wii U virtual console recently. I'd just rather own the game than subscribe to the premium nso. I also prefer the Wii U over the Switch for virtual console games especially because the Wii U allows me to play the available DS games using the touch gamepad. Thx for the vid, cheers.

That Vector filter you're using makes my soul weep.

I am glad they re-released this with all the extra content again. This really is the best game in the NES library, with only a couple that even come close.

Woah, 38 new SMB3 levels? This is the best retro game video I have seen in years, can’t wait to play them. Thanks Lady!

It's great they added the levels that should have been included in the first place. Another one of the endless amounts of frustrating, baffling, inexplicable, insane things that Nintendo has done and of course continues to do. I have a pack of those stupid cards in a drawer I don't remember buying them. I can't remember things anymore I feel so old!

Calling Doki Doki Panic "Doki Doki Literature Club" without stopping for laughs has to be the mos trolling I have watched in a youtube video for a long time

This is seriously one of my favorite channels!

I missed buying and playing the GBA SMB3 when it was on the Wii U eShop, so I’m glad it’s available again on Switch Online.

uh there's been a rom hack of Mario Advance 4 that has existed for years that added in the E-Reader levels. dunno why this is big news now

I remember being home sick from school, and I had this game. I played it all day!

This video was great! Some of my earliest memories are of playing this on the SMB Allstars on the Super Nintendo. It was also my first GBA game!

it's OK that our SMB2 is a Doki Doki Panic reskin...Shigeru Miyamoto and his crew worked on Doki Doki Panic, and when it came time to convert the game for American/international audiences, they approached the development of the game just like any other Mario game...

I found this channel recovering from surgery in the hospital a few days ago. Thanks for the in-depth entertainment

I can’t believe I never knew about these hidden levels

"At least we had Mr Blobby and they didn't" Fun fact- Walmart own Asda.

lady decade's videos a requirement for gracious living

Fantastic piece! As a console & PC gamer, i had no idea about all of this, thank you

Thank you so much for your high-quality content.

“Who cared about the Wii U?” I do, and I’ve been playing these levels for years.

It's so hard for many to ever play those unique levels due to that e-reader problem, and not all of even reached the U.S.

3:53 well that was unexpected. Did you know he wrote a song called “Don’t Do Anything Illegal”?

I'll never forget in Doki Doki Literature Club when it was revealed Monika was a blue hedgehog all along.

Oh yeah, I heard about these levels. As I recall we didn't get all of them in North America until it landed on the Wii U. Some of them do look neat though with how the combined elements from different games in a single level.

I was fortunate that the e-Reader was released just after my birthday and got the thing with my birthday money. Originally that Christmas they had released the first of three waves of the e-reader levels. They were fun and cool. It was also neat that the e-reader had released power up cards. With those you could use the hammer suit anywhere in the game. Like my cousin did in World 2...... Sadly I was supremely disappointed they never released the remaining cards. I read though I think in 2007 some guy from another country downloaded them on his computer and used a laser print to print them out and have them work in his eReader. But I couldn't get that here. Finally in 2017 the Nintendo WiiU shop released the game with all the extra levels and I played them thoroughly enjoying thrm.

Patrick star "I love you" seriously tho your great keep up the good work

Love your videos on Mario and Sonic lady decade. You have the support of the Juggalo community, whoop whoop

Love all your videos as I am an avid Super Mario Bros fan 😘

I kinda completely FORGOT that the GBA e-Reader EXISTED (with the cards that unlocked stuff in certain GBA games). Really sucks, too, because it makes these games essentially have “sectioned-off” content that you can’t access unless you can get ahold of the actual cards (which I’m sure aren’t easy to find or cheap) or are able to hack into the software itself.

Great video! Thanks for the fantastic content!

What I find more interesting than these levels, the original SMB 3 for NES has 15 unused levels that are in the game's code and inaccessible through normal means, but can be accessed with Game Genie codes. Some of the levels appear to be earlier, unfinished versions of levels, while others are unique.

Subscribed! Love the content!

i wish mario had a thing where if you collect all the hidden one ups in the game it would change the remaining worlds up, they would look different and be harder to beat than if you didnt find all the hidden one ups.

Wow super amazing discovery and every time I see a classic Mario or Sonic it always make me want to pick up the sticks and get down on it again .. Great video

Great channel, the only one I've "rung the bell" for to be honest.

I was going to point out these were all on the Wii U version, then I noticed you mentioned it. I didn’t think you’d miss that, but I care about the Wii U. Sort of. Haha.

So I recently acquired the levels I didn't get back in college. They are awesome.

2nd post worthy, I do wish the e reader and cards would of been successful.. it be fun to have a epic trading card game built around the cards and extra levels when I was in elementary school

6:47 nightmare fuel

I really enjoyed this video, So much I didn't know about thee lost Levels. God Bless and take care.

the e-reader. An accessory for the GBA that hadso much potential but just.... yea.

The random Charles Manson clip made me like immediately.

Lady Decade, you are absolutely delightful.

The wii u was dope. It had a small library that's the only negative of the console, but all the games were top notch.

@Lady Decade 3:45 Um lot's of people, myself included. I don't care if it wasn't popular, the WiiU was an excellent system greatly under appreciated!..

It's funny that they added so many new features to the game that ended up not being seen by most. With all of these things and the amount of levels mixing things up they could have essentially made a Super Mario 3.5 with 4 of it's own worlds and story. I also believe the shoe is the most underused item in Mario 3 so I'm glad to see that it got some more usage in the extra levels.

shigeru miyamoto provided the entertainment for half my life. This game is still fun, 30 years later

I remember gathering everything to get some of the levels, power ups and basically the earliest versions of speedruns. It was trippy to scan the feather card and use it in the main adventure.

I felt obligated to provide a correction but these new levels were not locked on the cartridge. The thing is they were never on the cartridge to begin with! The e-reader levels are essentially DLC on a physical cards. The dot codes on the cards are actual code containing the new level structure. Really, the only thing on the cartridge having to do with the e-reader levels are the new assets taken from previous games in the Mario Advance series so that they would be at the ready for when a level got scanned in. Hell, there are some assets at the ready for the e-reader levels that just never got used but can be if someone were to create a dot code card with the correct code on it to put said asset into a custom level. The last thing I can mention is the version of the GBA game on Wii U and Switch is actually modified a bit. Normally the cartridge could save 32 e-reader levels before having to delete some to add more room for new levels. This was modified for Wii U and Switch so all the levels that were ever created could be included.

After a good night of "Stomping Koopas" 11:17

I remember grabbing an e-reader and the card pacs off the shelf at GameStop and the guy said to me..if you’re getting that for the extra Mario 3 levels, it isn’t worth it. Oh how wrong he was…

Lady Decade videos - a necessity for gracious living.

I care about the Wii U version. In case I have to unsubscribe to Switch Online for financial reasons I can always play it on my Wii U. Speak for yourself Manson 😆

Still my favorite game in the whole franchise.

Mario games are a force not to be messed.these games are well, in my opinion

I'm jealous you got Mr. Blobby. I'll trade you Wal-Mart for him.

Don't want to be THAT guy, but these e-reader stages were available in the WiiU Virtual Console. It was even dumped as a rom and it's been distributed on rom sites for almost 10 years. Also, as a construtive comment: please avoid recording snes and gba footage using these filters (SuperEagle, I think?) because that is far from what the game looked like on the actual hardwares. It will make your videos more pleasant to watch, even if it doesn't sound like a big difference.

I'm playing this tonight. These levels are crazy!

Thought you were talking about the "Lost Stages" found in OG Super Mario Bros.3 Those are unlocked via glitches.

I have to ask, at 1:54 the console you are holding, how did you get that, i had the same one back in poland when i was like 5 years old. If i could get some details on how to obtain that i would love to have one for my collection. Thank you much, and awesome videos.

The main selling point for me to get an eReader was to play the classic NES games that at the time were not available anywhere else outside of hunting down the cartridges. I did get the Super Mario 3 card packs that were available, but with one GBA, how would I use them? Then I got the Game Boy Player and the link cable to connect my GBA to the GameCube. That worked.

I never got the GBA e-reader, let alone the cards, so I was beyond stoked to play those levels when they were patched-in to the Super Mario Advance 4 re-releases on the Wii U eshop and Game Boy Advance NSO app.

3:50 I spit out my coffee lol

This channel is like a fever dream

Did u know super mario 3 was actually doki doki literature club in Canada

Loved the gatekeeper impression

9:54 correction they're only found in Yoshi's Island and not super Mario Brothers 2

You have until March 27th to buy this on the Wii U; or homebrew a Wii or Wii u. Just renting it on the switch seems like just a tease.

with the exception of battlestar galactica, i dont support remakes of anything.... but if you wanted to play those levels you could always find a rom that had them unlocked. recently i played smb3(the real one, not a silly remake) with a personal challenge...i beat every single level in every single world.... the game is even better than i remembered from my childhood.....i also found a level akin to 3-1 from smb. where you could get infinite lives legally.

Oh wow, this is really cool!

Wow! A re-release worth buying. I especially liked the reskinning -- it's much truer to the original NES game. My one and only peeve with Mario All Stars was that the updated graphics for the games all looked like SMBW. I hope this is a sign that Nintendo has recovered its mojo.

Two corrections: 1. SMB 3 did in fact have horizontal plants. 2. Bumtpies were from Super Mario WORLD 2, not Super Mario Bros 2. Overall, though, great content. I had a few of those cards back in the day, but never bought the ereader. Lol

I wouldn't even go as far as naming it the best NES game, I'm not sure what would get that title but certainly kirby would be at least a step higher than SMB3

I subscribed to Lady Decade once, NEVER AGAIN!! (that's because I never unsubscribed.)

Love your's and Top Hat's videos! Cheers!

Super Mario Bros. 3 is, without question, the greatest video game ever made.

Are the levels on the GBA cart or on the cards? I remember the cards were a magnetic strip and those can hold quite a bit of personal data, not sure how many kilobytes or megabytes that translates into. If they were on the carts themselves you would think a rom hack would be able to unlock them.

I wish they would just make the games for sale on Switch! I won't "Netflix" games I can already play on original hardware, I'd happily buy the ones I want Also there is a game for PSP called Wipeout Pulse. We never got the DLC for that game over here and I was always bitter about it but now I figured out how to run it on my computer all these years later 🤣 love the video!
