You control the direction of SMB3 powerups by which side of the underneath of the block you hit (if you hit the right half, the power up goes left, and vice versa). Watching Kosmic play SMB3 is what made me realize he wasn't born in the 80s :P

Love you man. Great idea to seperate content like that.

This hack takes me back, makes me remember the games I played, Super Mario 63 was one as well, I found it when trying to look for Mario 64 lol. I didn't get all the star coins though...

I missed this the first time around, was still moving, but this is definitely one of the best rom hacks, and the fact that it's for SMB3 and mashes up 1, 2 and 3, awesome.

I'd have to say smb3 is my favorite nes game

Pushed the nes to its limit. Amazing stuff!

This was awesome! Haven't watched an entire Romhack video for ages but this one kept me hooked :D

I think it'd help to make an update video with this announcement. Some people might miss it

OK that’s so cool how you can see ROMhack replacing the tiles as you load the level

I feel like I'm the odd one out, but I actually really like that there was so much stuff in SMB3, like Goomba's Shoe, the arrow blocks, and the like, that only ever appear once. It makes those levels more special and unique I think.

Dude kosmic is my childhood hero. His smb1 strats were like playing video games for real. So glad he still makes content

The secret final boss of this game is pretty insane too, Id say its worth going for all the start coins

This was impressive, and every single time I get to see SMB3 again I wonder why Kosmic never thought it was the greatest of all Marios like I always did!

oh heck yeah; im glad to finally see 3mix i think i made a comment about it ages ago and i still think its such an insanely cool hack and even though its smb3 rather than smb i always thought itd be real fun to see you play it

I loved watching this, thank you Kosmic, I would love to see more. I hope you have a great day dude

26:33 I'm impressed he can perfectly mimic the Zeus death sound effect from CS:GO

Subscribed to the new channel. Doesn't affect me too much as to how many if your channels I'm subscribed to. Always enjoy your content!

I've suggested this romhack for quite a while, I knew you would love it! Thanks for listening!

I was already subscribed to KosmicExtra.😄 Amazing looking romhack, kudos to the people involved.👍

Bro please keep playing this. Love the romhack series!

I was watching another one of your videos while you uploaded this lol.

@Kosmic: why the star power-up was so short, the mushroom with stars are a check point, regardless if you get a power-up from the check points the star power-up will immediatly end after crossing check point, the same thing happen if you get an actual power-up that change mario power-state even if that power-up was already obtain obviously except the star power-up and 1-up mushroom. This is a Super mario bros.3 mechanic

Haha, I love how the new channel's logo has a little Luigi. ;D

Omg I’ve been secretly waiting for you to do a video on this ROM hack. 😮 Plz I want a part 2 and beyond until you finish the ROM hack.

At first I read it as "bosses AS powerups." Now there's a romhack idea.

i need to play this romhack

Kosmic, you are a a delight to watch. Hope the channel split helps!

Best romhack in a while! And I'm excited for the reworked channels :)

Loved it! Thx Kosmic!

I'm definitely a big fan of the Romhack Wednesdays in particular, so having them separated out is very handy. =)

i've played this one a bunch, super impressive rom hack. the amount of stuff they were able to cram into this without breaking the nes's limits is pretty crazy!

This is amazing, I can't wait for the rest of this one.

Thanks for the content brother!

Captain Southbird is the man when it comes to Super Mario Bros 3.

Dude, the direction stars and mushrooms go depend on which side of the block you hit, if you hit the left side of the block, it goes right and the other way around.

That music in 1-7 was slapping!

I've often thought "If I made a SMB romhack-" but now I don't need to because this already exists and it's amazing

Incredibly impressive game. Subbed your other channel months ago, great idea to organize and optimize viewership 👍▶️

Very good rom hack, i've played this twice and i'm doing it yet again.

I'm not even one minute in and I recognize that romhack! I have left it lying around somewhere on my disk for literal years... now I feel deterred of watching the whole thing out of fear of getting spoiled lol

the overworld music being from super paper mario is a very good choice

Very creative and well executed rom hack

0:26 Hi Carl!

Mushrooms/moving items spawned from a block in SMB3 always travel the opposite direction of the player relative to the block. So if the player is to the left of the block once the item has finished the spawn animation, the item will travel to the right. And if the player is to the right of the block, the item will travel to the left.

Screen wrap is so neat.

Lol!!! Wow. So, I was watching this, when, coincidentally, the saxophone playing busker outside of my apartment window somehow decided to play a jazz version of the underground smb1 music!! It was both awesome (the guy is GOOD), and kind of a strange trip- one of those coincidences that seems almost impossibly unlikely, but, well, there it was. Very cool 👍 😎.

I'm kinda sad I ended up missing this stream because my mind's blown just watching this highlight video and I know that if I was watching the stream the chat would just be FLOODED with my confused excited reactions lol

Loved seeing you play this. 3 Mix isn't just one of my favorite hacks, it's one of my favorite games ever. Probably why I ran it for 2 years. ^_^

Can I just say *Modern Year* is a great time to be alive. A man entertain tens of thousands of people by playing a video game from 35 years ago.

Love the mario romhacking community, my favorite gaming niche.

The star coin sound effect is from Mario Maker when you get all the red coins and get a key

i havent played 3 mix in a long time, such a great rom hack!

Thank you for everything!

I see Bowser Jr in the thumbnail, I click. But seriously I’ve never seen a Mario 3 romhack with this much polish before!

@Kosmic: Because it is NES Super mario bros.3 physic you can't stomp on stomp able enemies underwater that only became a thing in Super mario world, And GBA version of Super mario bros.3 since Super mario bros.3 in Super mario Advance 4 kind of added the Super mario world mechanic. The fire chomp in this game will re-spond if you defeat them they can be defeated by stomp, fire ball, tail swip, the only way to prevent them from re-sponding, keep away from them untill they explode.

God I remember playing this when I was younger. I even uploaded a boss video of it, but since I played it on a 6x slow emulator and sped it up, it sounds all weird lol

oh wow, exciting changes to channel :0

what a cool love letter to early mario games, cool hack

What you didn’t recognize in World 1 was 1-4 with thwomps

Romhacks are my favorite thing about this channel.

17:30 that would be because the original game couldn't swim there lol

This was a really cool romhack

11:44 If you had a dragon twice as fat and tall fall on you, wouldn't you be injured if not killed too? Asking for a friend!

@Kosmic: I played that Super mario bros.3 rom hack 100% complete however I did not play it on a NES since I did not have one. I did have a NES/FC emulator and I also downloaded the Rom not in a public website not in a web site neither since downloading Rom from web site public or private where not a thing anymore at that time because it is illegal, and I had to download the lunar patch software so I could put the Super mario bros. 3 mix patch into a Rom of Super mario bros.3. Since it is just a patch version the only issue is on the map screen when it scroll it kind of flash, but the entire game works fine.

See ya on Kosmic Speedrun!

its even more impressive bc this hack is old i assume the smb3 romhacking scene wasnt as mature as it is now

I love all the SML2 music

I saw a video where Mitchflowerpower played this game, it's totally nuts, and I love it.

Why no 3mix in the title or description? XD and holy late to the party haha good stuff

Super Mario Bro 3Mix is just amazing.

Have you ever considered speed running vs super Mario bros? Considering it a bit of a mashup of smb1 & lost levels it seems it might be right up your alley.

I feel incredible blueballed here, can't find part two of this.

the mushrooms don't go the otherway just sometimes it will go the opposite way if you hit the block on the left the shroom goes to the right and hit the block on the right the shroom goes left.

30:31 Kosmic during a thunderstorm

I was always a Mario Adventure fan - I’ve got one of those Anberic devices coming my way and this looks like a fun addition, if it’ll run on there.

Yeah, I thought Mario Adventure would remain the best Mario 3 hack simce I was 12. Then I discovered 3mix.

This is AWESOME

Imagine time travelling back to the past and release this to the people back then...

I don't like that you can't loose lives. At least in the physical NES copy I have.

i remember playing through almost the whole game on an emulator on my graphing calculator a while ago..

The weirdest thing about this game I still feel is the fact they removed the flip mario did in smb3

In accordance with other recent videos I've commented on, I feel obligated to say: You sure weren't Luigi in this one.

hey do you have a video abt the 'maximum score' that you can get or highest posible score in world 1-1 smb

Can’t wait for the day they remake every smb3 level in smb3

I miss rom hacks on this channel 😢

Finally! SMB3MIX!

He, i was wondering if you can cover gameplay for the Super Mario World hack known as "Iluminate"? I recently downloaded it, it's pretty tricky. I also just got "Return To Dinosaur Land" and "Tatanga's Return" such great games

3 Mix has been out for a while

I think the secret 1 ups arent there because the creator didn't know about them

The real name isn't really BirdO it is Ostro BirdO is the Shy Guy riding and big bird like an Ostrich that comes directly from the Super Mario Brothers Manual USA version but I think they should of call it Eggo since it spit eggs at you. But know why they didn't because that name was used for frozen waffles.

Mario 3mix let’sa go!

I have this nes cartridge it's pretty fun

This is something random... but can someone plz answer me why when I do the flagpole glitch, at the right of the screen appears like 5 number Ones?

3 mix has this stuff in it? I played it a few years ago and I don’t remember it having some of this stuff. I even 100% cleared it. 🤔 was there an update or something?

I played SMB3 Mix Before and Besides Super Mario 63, It’s one of the best rom hacks I’ve ever played

I get it, Junioooooooor appears in the Dream World because his inclusion in the Mario series is an existential nightmare!

I feel like Nintendo’s going to sue me just for watching this.

I have played this before when I was like 27 years old.

What was the music in that final world 1 castle?
