[@ShoBlai]

Ok

[@Reth_Hard]

I think it might be cool if you could play this rom with someone else! I'm not sure if there a way to do this with real hardware but you probably know that emulators allows you to connect over internet.

[@chrideedee]

Creator: If the player touches a coin, I want you to act like they touched an enemy. Game: Which enemy? Creator: What do you mean? Game: Well, there can be multiple enemies on the screen at once. Which one should I act like I touched? Creator: That's not what I meant. Just, like, a generic enemy. Game: Okay, I guess I'll just pick one arbitrarily.

[@WhiteDragon103]

That makes sense. They're moving the hitbox to the coin when a coin collection is detected. That's why spinies can be jumped on.

[@PeterSvP]

It picks the last entity form the entities data. Usually rightmost enemy but this data can be arbitrary. Powerups, platforms and firebars can be picked. I debugged the rom and it was funny

[@PeterSvP]

And also the routine mess up with whatever entity it picked.

[@TheElcentralen]

@@PeterSvP guess you fall and dont bounce when a entety or enemy does not exist. Also if you duck coins cant damage you if you are at least big Mario?

[@PeterSvP]

@@TheElcentralen is kinda this. That's why everything glitches sometimes 🤣

[@notalostnumber8660]

shiny, yet deadly coins

[@excalibomb]

gotta love ceave

[@quinn7894]

Ugh. I made the same comment, but you were first.

[@bestberryj]

Rip Ceave Came down here looking for this comment

[@ArloMathis]

I was *just* thinking this and checking the channel to see if I missed any uploads. Nope. :(

[@SirLampsALot]

@@bestberryj did he die?

[@sarysa]

Interesting concept, but feels like the developer went above their weight class with this one. If I were to guess, when a coin is collected they create an enemy on top of it and do enemy collision code immediately after, then move it back. That would explain all the erratic enemy kills. There are only 5 slots devoted to enemies and they're often all filled.

[@Zalied]

im barely into the video and that was my guess as well. its also why repeated coin bounces causes you to not bounce sometimes since youve killed all available enemies. afaik its a very creative way to do the concept if mario touches coin teleport enemy hitbox to location if luigi touches coin dont. It wouldnt surprise me if bouncing on coins wasnt even an intended mechanic when first designing the game but was worked in later due to the way it appears to handle enemies. it also appears to give him a coin when killing enemies so it adds up

[@arfansthename]

i think the developer was just rushed on getting this out so he forgot to playtest and/or debug the game

[@lior_haddad]

Actually, I believe what was actually done was that collecting coins runs the "on enemy collision" code directly, which is what actually causes the enemies to be hit and otherwise unhittable things to change. Presumably the registers are set up to either hit a specific slot or some latest slot...

[@MattMarkYT]

But what about Mario dying to the coins even when he has a star? And the hammer bro standing on coins? I'm not experienced with the logistics of smb1.

[@sarysa]

@@arfansthename Or at least saw a viable workaround with the enemy teleporting/ID change strat. (later on in the video it's clear that enemy slots are being set to para-dry bones) This developer clearly has ASM skill, though, I'm sure the sequel will have dedicated code to handle the coin behavior.

[@ahuhu]

i know this idea has been around for a while but the (buggy) implementation is even funnier lmao

[@raz0rblade06]

Ah, the shiny yet deadly coins. Please come back, Ceave.

[@Mrx2848]

15:00 "it's jostling, dude - I don't know who Jocelyn is, but she's here!" That's a Groucho Marx-level pun, Kosmic. I commend you!

[@4the0cean]

This is the funniest thing I've seen in a bit. You get the star and immediately die with it, then you go to get a mushroom and it falls through the ground. It was just too funny. Thanks for the entertainment.

[@PierceArner]

10:29 - Since the enemy spawned because the floating platform was transformed, I think it retained the long hitbox from that platform. (Edit: Looks like you talk about this more at 19:22)

[@MikePouch]

9:15 had me busting out laughing. So unexpected!! Hahaha!

[@MattIsTheCat]

According to the chat logs that is not what they said. This is Chris Hansen and we are doing a story… on adults who go to type comments on KZbin videos called Hansen VS memes.

[@PierceArner]

Kosmic's reactions to unexpected shenanigans like that and 22:41 are just the best!

[@ShimmeringSpectrum]

Even though this was janky as heck, it was a really cool concept to see pulled off at all.

[@PeterSvP]

8:31 - if you read my prev comment. Bottom coin spawns a invisible Koopa under you. It becomes shell. The top coin collects and you hit the invisible shell. At the same frame this same fake enemy teleports somewhere else and possible owerwrires entities. The routine that spawns a koopa under you is glitched. It can take random entity to put under you so you bounce. Whoever implemented this thing definitely knew what he was doing but abandoned it as is. Abusing entity data like this is impossibly hard and to extents that it usually works its masterpiece 😊

[@LychkovIA]

As someone who saw the original stream, gotta give huge props to the editor for smoothly editing down that beginning. The Luigi glide-clip moment was golden, glad it was kept in.

[@williambarnes5023]

If I had made this game, I would have a 10 on the multi-coin blocks, and every time you hit them they would count down so you could see how many were left. And it would count down into the negatives because they would still have more than ten coins.

[@miwiki6]

2:54 this is why i love speedrunners

[@ChicDead26]

Surely one of the most technically impressive romhacks so far. Kudos to NesDraug! I hate all the smallfire preventions and similar stuff tho...

[@aloysiuskurnia7643]

This hack feels simultaneously extremely janky and extremely polished, like whoa

[@aurafox1]

Theory about the coin bouncing: Maybe the bouncing mechanic is hard-coded to do damage on an enemy and gets confused if it's forced and you don't actually have an enemy there. If the sprite slots are full, then the game might assume you must've jumped on one of the sprite slots that are already loaded. This bug might be the reason the author made reskinned buzzy beetles instead of Spinies because real spinies would sporadically kill Mario for no reason. Notably, the Lakitu in 5-1 seems to despawn before the coins in the level to prevent such a thing from happening with the reskinned spinies.

[@mina86]

The real question is, do coin bars kill Luigi?

[@gaspardh.7643]

Kosmic to the creator : "How many bugs are there?" Creator : "YES."

[@RetroCheats]

For the original NES game, there are game genie codes where if you touch a coin (powerups & other things) can kill you as well, if anyone is interested.

[@Acts19quiz]

19:50 The water music sounds like Mario Learns Typing Underwater. 24:55 Great boss design. XD (Wario as boss is cool, though) 26:43 That drawn-out cutscene with the slow movement and funky music with super-wide castle is great. 27:00 Hiding a Dry Bones as a Wario drape is the most cheaty Wario thing ever. 27:50 The music changes for the boss? Straight from All-Stars. It seems there are some issues with collision detection. Still, cool hack!

[@Manabender]

2:54 This was hilarious. 7:22 THE FIRE BARS ARE COIN BARS, I LOVE IT, 10/10 FOR DETAIL, BEST HACK EVER

[@DietChugg]

After playing this hack I went back to the original and I kept double guessing myself right before jumping for a coin thinking it's gonna kill me. XD

[@dekade420]

7:22 I just realized the firebars are made of tiny coins

[@good_guy_SG]

10:47 craziest 1up bullet bill kill ever

[@guepardo_6308]

It's funny how Kosmic's videos are never really just about playing Mario but actually all about doing glitches

[@stevenjones8575]

1up kicks. No small fire. NesDraug giveth, and NesDraug taketh away.

[@ibookboyuk]

😊 9:10 This disappearing mushroom is the funniest thing I have seen in a long time. 😊

[@HardToBeAPoopGod]

7:13 i haven't seen anyone comment it yet but the music is World 5 from Wario Blast! love that game and soundtrack 💛

[@MichelleSleeper]

With all of the fun bugs, this hack really should be called Super Mario Bros. But Reality Is Collapsing In On Itself

[@jestfullgremblim8002]

Hahaha

[@pokequeenrrpg]

super bizarro bros lol

[@stapler942]

This is like the anti-Wario Land. Like an ascetic Mario, except Luigi did not take a vow of poverty like his brother so he can collect all the coins he wants.

[@quinn7894]

22:41 Kosmic freaks out

[@konohasaiyajin]

10/10 experience watching this one

[@1ByteUniverse]

The music in this romhack is actually great, and I also like the level design and concept. Good job hack developer!

[@koopakape]

Man, so much hilarious stuff happened in just the first 5 mins of this video, I'm gonna call it your best so far hahaha

[@MunaAlaneme]

11:37 - 11:41 Overworld -> game over (perfect music transition 1)

[@clinton6087]

It would be really awesome if you did a video where you showcase your wall clips and pipe jumps and general techniques that you use. Keep the videos coming man.

[@Bisqwit]

I have to say, one thing this hack does better than the original game is Mario’s sprite. It looks better.

[@JakeRazorClawson]

Super entertaining hack. Loved watching Nesdraug play two player mode on his channel, extra grateful to see Kosmic game through it all. Perhaps smallfire mario will be available in the sequel, which hopefully also has tons of glitch features 🌀

[@kaldogorath]

I love the level design in this hack, I think it would make a great hack without the gimmick too - ie normal coins and enemies

[@infinitelybanta]

Cool about the NES Gauntlet! I’ll try to stop by, I really enjoyed the mainline Mario marathon, though I didn’t catch it in real time… or even watch it in one sitting. You’re a maniac, Kosmic, you have my respect!

[@M_Alexander]

I really appreciate how confused you are during this

[@infinitelybanta]

The Super Mario sprite looks like some sort of generic, legally distinct jumping man. His mustache is slightly unsettling. The music is sort of the same thing too!

[@Pokefan462]

14:26 The only context in which "That actually makes sense" could ever be applied to that sentence is this game.

[@zaku28]

man the vibes in your videos are always so good. The chuckles especially, always puts a smile on my face ^o^

[@AgdaFingers]

An even deadlier version of the do not touch coins challenge in the New Super Mario Bros. Series

[@Cristian.Carlos92]

28:10 is part of the soundtrack of Wario Land, Super Mario Land 3 for Game Boy.

[@mchevre]

Thank you. During that part chat was saying it was Wario's theme from Mario Land 2 but I was like "could've sworn this is from Wario Land..." I guessed it was the final battle theme from Wario Land but interestingly it's actually the generic boss theme from Wario Land, not the final battle. Definitely not from Mario land 2 though!

[@staudinga]

09:10 that was absolutely hilarious

[@kanlalonde1356]

Shiny, yet deadly...

[@gametale3]

this is less "touching a coin kills you" and more "i have no idea whats happening, please dont arbitrarily kill me"

[@ecksdee9768]

i'm currently sick right now and this video made my day, thank you kosmic

[@aajlakapsio6715]

Loving ur videos! Thanks dude. Alsoo the out of tune theme is somehow super fitting to this game xD

[@juniemarin]

I've never seen Kosmic this confused by a romhack and I love it 😅

[@rootkit0]

Saw the stream, now I'm here, having just as much fun! Fantastic video😁

[@sportsjefe]

23:20 Hello, AtomicNeWT

[@Iudayus]

walked away and came back legitimately forgot the challenge and was thinking "why is he not grabbing coins?"

[@Dwedit]

I saw this kind of Romhack (coins harm you) earlier when it was named "Communist Mario"

[@ibookboyuk]

Kosmic. l've played Super Mario Bros. 1 since the cabinet here in the 1980s and the NES. I still love the game and thank you so much for these videos because it's keeping the game fresh and interesting.

[@clockworkengine]

FOOLS! Bro-Op IS the two player mode. The true ending was waiting the entire time.

[@672thesketchgirl]

This is how Nicobbq plays Mario games

[@d4.2g]

Per your recommendation in the comments of one of your other videos a while back I grabbed an everdrive. After some consideration I decided to get one for my turbografx 16 since the system is basically impossible to collect for without going broke. Of course I had to find an SMB ROM for it lol. It's pretty clear that the system is clocked a bit higher so the music and gameplay are sped up quite a bit and the colors are just a bit off.

[@quinn7894]

Shiny, but DEADLY coins.

[@random832]

It looks like whenever you touch a coin it 'redirects' your action [hitting it from the side or the top] to the first object on the screen, which is an arbitrary type [the bullet bill sound or the random shells that have appeared] if there aren't any, possibly explaining why they made it so that you can safely bounce off of spinies? EDIT: I noticed in the sections with actual spinies [the stars], there either weren't any coins, or they were in a 1-high row with solid blocks on top of them at 26:30, so you couldn't jump on them.

[@randy7894]

Love the mushroom powerup sprite. He's so chunky.

[@DinoCuber]

The glitches made the game really entertaining to watch! Lol

[@CI-._.-ID]

6:48 what if you... like... change the flagpole to be something different with coins?

[@scottspangler6363]

I love the Wario land theme used for the boss music!!

[@SuperYoonHo]

Thanks so much Kosmic keep it up

[@matheuscabral9618]

10:47 did the game create a scroll stopping enemy there?

[@user57382-s]

hey kosmic i know its a long question but how do you capture nes can you list the items that you use please?

[@Thermo-Lizard]

Super Mario bros: nicobbq edition

[@Mythraen]

NESDraug explained weird stuff was supposed to happen when you touch a coin in Kosmic's stream, and Kosmic completely missed it.

[@joshuabruner9676]

10:46 nice killing fire flower with fire

[@HardToBeAPoopGod]

the water level music is so beautifully rearranged?? i hope it's somewhere on youtube :]

[@HardToBeAPoopGod]

oh and the tune in 7:13 is from Wario Blast (stage 5 i believe?), absolute banger

[@Capless_Mario_Sixty_Four]

The matter of fact: Never trust question blocks. Also, trust the blocks that has an exclamatory.

[@jevogroni4829]

that hack is insane, never seen anything so wild

[@mikeprado30]

You thought at the end was waiting the Princess? TOO BAD! WALUIGI TIME!

[@bobby4tw]

Music is really awesome!

[@alicyjinx8923]

This is like Default Dan

[@PeterSvP]

I debugged this rom. The game is spawning an enemy under you so you stomp and bounce off it then the routine is teleporting the enemy offscreen. Though this sometimes rewrites entity data in a funny way creating very funny bugs

[@607]

That's the first time we've heard Wario Land music in any of these, I think?

[@MrTASer]

There are several instances in the video that must be made clip-ed I'm not making cos I'm too lazy to use my touch screen and all that😢

[@jiskithehusky9094]

Grabbing them out of habit reminds me of when I used to do the opposite in Minecraft. To fly in some modpacks, I’d use a Blaze morph, but that meant I couldn’t touch water. Then when I wasn’t that morph or even in vanilla, I’d instinctively try to avoid water if I came across some while mining or something

[@Toprak135]

Essentially: No coins allowed.

[@TMSB_Fan]

I saw this concept 1. Billion times
