2 Players at Once in Super Mario Bros. NES | 2 Players Hack 

Hey everyone! Let me know if you want another episode of Super Mario Bros. 2 Player, and also be sure to check out my buddy Lair's channel here: goo.gl/m9LTN1 He makes some awesome content and is one of my best friends! Thanks for watching! -Darby

Now, that's what we called "Bros." right?

I wish nintendo put these kind of rom hacks on the online service to give it more value

This game doesnt ruin friendships like the other ones

Thanks for having me on to play this! It’s one of my favorite gaming experiences. I never thought I’d be able to play SMB like this and even watching it back now it still kind of blows my mind how well it all worked.

When i first played smb1 i was disapointed when i found out how 2 player mode works, this hack made my dream come true!!

Fans does what Nintendon't

6:05 JINX!!!!!😃😃😃😃😃

0:18 you were right on that Mario Mutiverse a day or two ago. Trolls are watching

"I was pixels deep in that cheep cheep" haha amazing. This game looks awesome and you guys doing the running commentary totally brings me back to when I was a kid playing this game for days and days on end having lots of fun. Love it ❤️👍🏻

👨🏻: Mario 👨🏻+🍄: Super Mario 👨🏻+🌷: Fire Mario 👨🏻+🌟: Star Man (Thats how I was told, or something, You may disagree, but this is how i remember calling them)

4:26 It looks like Luigi is angry on the pit the Mario fell into. XD

What if they made 2 player co-op in super mario bros. 3 😆 And I mean like this one , not one at a time.

4 players would be Mario,Luigi,Wario and Waluigi

Every time toad said "thank you dudes" it made me think of bill and Ted.

i must say, it's so wholesome to see you two playing in co-op just having a blast c:

Very impressive hack! Now imagine how fun SMB3 multiplayer would be!

This is so awesome. Just last week I found someone's commented source code for Super Mario Bros. and after studying it generally for a few hours I was thinking that this very thing should be possible given the unused space in memory and the way the functions to handle Mario and Luigi are laid out. Seeing that somebody else had the same idea and got it to really work is just amazing to see. It really makes me wonder if this was a planned game mode for a while, and then they just thought it would be too confusing for people who are just discovering platformers. Maybe that and sprite flicker made them hesitant to do it, but since Mario Bros. was co-op in nearly the same way but just on a static screen it makes sense that they would have at least tried that in this engine. Having this in wide screen with something like Mario Maker 2 would be so much damn fun, especially through online play.

This is what Smb 1 should be!!!!! Smb (Super Mario Bros 1)

I like the Green Fireballs for Fire Luigi

This is amazing I've always wanted this in the original super mario bros! :D

See this is the reason why Local multiplayer co-op is the best, just wait few minute then friendly fist will flying around to distract each other.

+Are You Ready For This? - * dies* +*laughs* -Yup

this is now my favorite mario hack

This is so fun! I can't believe no one has ever done this before it's just a perfect idea I hope someone does this with mario 2 and mario 3 too

That's a pretty good mod for Mario Bros.

I've been having kind of a rough time lately, but this video made me laugh several times, and I severely needed it. I could see my brother and I playing it with this hack and acting the exact same way.

Definitely want more of this! Too many good quotes.

Wow, I'm really impressed that the rom hack creator was able to get the game run so smoothly with 2 players. Also, I mentioned you doing a collab with Lair in your last livestream. Funny that.

Lol Luigi's fireballs look like he's shooting snot

This is so cool man, I just started watching this series and I don't know how many episodes you made, but it's awesome so far!!! :)

8:34 Darby: how r u alive Layer(sorry for not spelling it right): its pure skills

This is beyond amazing! The two of you in a video and also it being this! Great job dudes!

The manual for SMB 1 calls him "fiery mario"

It's really cool that you both had so much fun with this hack. Super Mario Bros originally intended to have co-op, much like its predecessor Mario Bros, but co-op was cut do to hard-ware limitations. It's just so cool to see that idea come to life with this hack.

I love this these co ops with lair always make me happy they make me laugh 😊

I don’t know why but this is amazing! This looks much more fun than the original. Maybe co-op versions are what we need for world peace ^_^

2:06 Darby adopts Lair to be his son

Can't wait for part 2! This is my new favourite channel

I think it's really cool how someone took the time to make a mod that add 2 players in a way that Nintendo themselves would be proud of.

Super Darby Pals. Best Super Mario Bros. Rom Hack, Ever.

"2 Bros, 1 Up"

"Hey guys" haha loved how he jumped out at the beginning

Imagine if when you beat Bowser at 8-4 it said 9-1 and gave you the first stage of the Lost Levels with all your score end power ups and lives that would be cool

Lair: I finally got the top this time; That’s what she said

This is actually amazing. I wouldn't have thought it was possible.

20:36 Froggy Fortress! I love this. Keep up the good work, you two.

Now the two player mode will FINALLY go by its name! ❤️

"Why'd, you do that mario?"

cool stuff is happening in 20:36

6:05 I like how both of you say Thank You Dudes!

4:30 "Are you serious, Mario?"

been awhile since lair was on the channel, a treat.

11:09 - This... needs context.

Cool video BTG! And yes, like William Afton, *i ALWAYS come back!*

Fire Mario is called the Angry Pyro Lord, devastator of worlds. His wrath is infinite and no one is safe from his burning rage.

CANT BELIEVE HOW SMOOTH IT PLAYS........ITS LIKE A DREAM COME TRUE

8:59 reminds me of the Flintstones Fred and Barney running from trouble

2:15 in old smb when you are small mario and u eat a fire flower it still only gets you into big mario

I like how it requires some amount of cooperation and coordination.

It is Fire Mario, but in Super Mario Bros. it's Fiery Mario.

Super Mario Dudes save toads

"I just have to make sure that I don't get INSIDE of you and get confused"XD

That looks really fun! I enjoyed the video!

This video is great, hope to play this with some friends... If I get the chance of.

Consider me impressed! Never thought this would be possible on NES.

I remember this was the very first BTG vid I ever watch! Such a life changer!😌

I have been waiting for this since Super Mario World Multiplayer! I am so glad it's here.

Can you do a part 2??

My dream as a kid, I have a memory of my sister and my cousin playing one life on the same screen and I thought it was amazing. However it's likely it is only one of those false memories.

You guys play so cute together, especially that intro....

0:15 gotta love the trolls that are even worse than SMM

Okay, well to save you some frustration, lemme tell you how to run this for anyone who doesn’t know: you need the patch file (by CorpseGrinder. Google Super Mario Bros Two Players Hack) which will be an RSN file for...SOME reason I don’t understand. Whatever. Change the “rsn” extension to “rar.” Unzip/extract the new file with the “rar” extension. There will be two files, a “read me” (txt) file and an “xdelta” file. Save the xdelta file. Now you need the original smb rom. I won’t say where to get it but you NEED to make sure the rom is the same one listed on the site (under rom/ISO information) or this won’t work. Get the rom and also get an xdelta (or “delta”) rom patcher. Select the rom as the source and the xdelta file as the patch. Apply the patch. Open the new patched file in an emulator and this should run. Boom. NO ONE explained ANY of this to me so yeah, there you go. If you’re using a SNES mini, import the game you patched into hakchi. Allow it to apply a second patch. Use KachiKachi as your emulation core.

There's actually a mod of this in super Mario world

"I just have to make sure I don't get inside of you and get confused" I'm dead B!!! 🤣😂

Darby Deaths: 8 Lair Deaths: 10 Darby Wins With The Less Deaths with Only 8 And Lair Has Lost With The Most Deaths With Only 10

It took people this long to add 2 Player?

This is awesome

I think once Mario gets the fire flower his name is Dave.

“Pixels deep in that cheep-cheep” hahaha!

Yup. Fire Mario, Fire Luigi. As for that infinite 1-up glitch, I NEVER COULD DO THAT SHIT, lolz I tried for so long, I just never could figure it out. lolz This was so funny and entertaining. If only I had more time with local co-op when I was younger...

#pixels-deep-in-that-cheap-cheap

I think this might be more fun than the Co-op in NSMBW, as you have to play together and can't combine forces. And have to be caredul that both of use makes it out alive saves from trolling each other

Oh how I wished for this when I got it back in the days. I bet we all did! We were on vacation when I got nes and the caravan had a black and white TV. I still remember getting home and putting it on a color TV. I still play it lol and still love that blue sky. 🌏👈🎩❤ Thanks for doing this🖐

This video Made me smile

Love ur channel!

Awesome video. Do this with more Mario games.

i watched your content while making my rom hack!

2 Plumbers Are Better Than 1

Darby can you try planing this level EFF0-0000-03D3-BE4D there is ten in the series or anyone can play this

Random lava bubble: i’m princess now I’m toad, i’m princess. I am princess now I’m toad, I’m princess princess princess princess. Me: WILL YOU CUT THAT OUT!?!?!?!?

Lowkey jealous, wish I had someone to co-op with like that. Had a blast watching you tho! XD

Another episode please

Play it in mario maker

Hey BTG, I was wondering how to patch the file to the original SMB1, I can't seem to patch it with Flips (which is what I usually use to patch rom hacks) and I don't know what I need to patch it. Is there a separate program to patch it? Or is it something else I need to do?

Jeez! I dreamt about this simultaneous SMB hack! It's amazing!

i wanna see this on snes

Who's here before 100 views or 100 comments me
