ROM Hack NSMB Hacks?

[Costello]

Hello,

I've heard about this wonderful piece of software called "NSMB editor" (can be found here: http://treeki.googlepages.com/ )
Now I've come to wonder if it's possible to edit multiplayer levels. Or maybe to find a patch that already has edited/custom multiplayer levels.

NSMB multiplayer (with shaun) was the funniest game I've ever played.
I wept with laughter so many times while playing it, that was one of the best play times of my life.

Now the only downside was the lack of levels. 5 is clearly not enough when you play the same levels for 2 hours every day.
I'm going to be on a 2.5 weeks trip with shaun so we would be quite glad to be able to play other levels

If you have any information or know any way to do so, please post here!

Thanks

This would be my premier request for the editor too, NSMB's multiplayer is the most fun I've ever had in a 2P VS situation, and it certainly beats out most of Mario's other multiplayer games.

glad you agree on this

I think I better ask the author of the NSMB editor, maybe he knows a way to edit the multiplayer levels.
I'll invite him to our boards!

Ah, me and my brother have had some fun times with NSMB playing multiplayer.

Really do wish that Nintendo would have added more levels, options, and possibly Wi-Fi to the multiplayer game :

Yep, multi-player on the pipes level with mega mushrooms!

The ice/snow level is fun too with blue shells... I reckon it's amazing that someone actually made a level editor, something I could never do.

Actually, I believe it was famous critic Pauline Kael who first said that.

Oh! Renewed interest in NSMB hacking I see...

If you guys don't remember me, I'm Tanks, one of the guys working on New Retro Mario Bros.

Anyway, My ultimate goal in this project is, infact, to have a kick ass multiplayer hack. Now to answer the question, Yes, you can. I have not tested when multiplayer is run, but theoretically, if you and a friend both have the hacked ROM, then you can play the hacked levels against each other.

As for the download play levels, they're contained within .narc files. Unless we can get a better .narc decrypter and compiler, we'll never be able to get anywhere with those. It is my guess though that the files inside the .narc mimic those of the actual multiplayer.

EDIT:

And Costello, the guy is a bit shy... (He's actually 13 now, but he coded the editor at twelve...) If you need to get in contact with him, just ask me or Sonicandtails, another NSMB hacker and member of this board.

Yes I have no doubt this would work, but I don't know how to technically edit the multiplayer levels.
The editor only seems to edit normal (single player) level files.
Maybe if I replaced the single player level files with multiplayer levels, the editor would let me edit them, but I don't really know where to start.

Can you follow your assumption and give the filename of the aforementioned narc files ?
EDIT : sorry I've found them...

 

[Costello]

Following my previous post, I can't seem to find the multiplayer level files anyway.

Following my previous post, I can't seem to find the multiplayer level files anyway.

They should be at the bottom of the list of levels to select. They're marked as "World 10-*insert level number here*." The multiplayer levels should be the first ones on the list. (I believe the first six) The ones under those could be the beta levels... not entirely sure though...

If you need any help with use of the editor - It has a few a lot of bugs still :/ - you might want to consult the "new retro mario bros?" thread. I mentioned a few things on how to save objects correctly.

-----------------------------------------------------------------------------------------------

I hope you don't consider this advertising or anything, but I've got a little blog open that I'm running with Sonicandtails for the hack. We'll be updating people on our hack from there, as well as here and on another forum. I'm doing this in this thread because I don't want to bump an old thread. I'm also being a bit lazy and am not creating a new one...

Anyway, here's the link...

Yeah, basically this.
World 9 is how the Mushroom/Toad Houses are listed; world 10 is the multiplayer levels and unused levels. All the numbering is messed up, it basically just takes the level names and converts them into understandable things, for example D_04_2.bin becomes World 4-4 area 2.
Keep in mind that editing multiplayer levels will only work locally.
You'll need to edit the NARC files in the "archive" folder for download play. I forget the exact names, I think they're something like "Dat_.narc".

I really don't know the origin of the unused levels - They could be beta or test levels, I never saw them in demo videos though.
Some of them seem completable, some aren't. I tried playing them by file swapping; only the first worked, the second crashed the game and I didn't feel like trying the rest. (I was doing this by editing the FAT in a hex editor, so.. Maybe I screwed something up. I might try it again with Nitro Explorer another day.)
Opening them in my editor shows obvious beta things. The one level I could play had glitched tiles (probably removed/changed) but had no way to complete it.
The others had some things like flagpoles with a block on the base (seen in some beta videos).

I'm the coder of the editor and probably the only one who's ever hacked NSMB in as in-depth.. Seeing my old editor makes me ashamed. @_@ It's really badly coded, full of bugs and random problems. And made in Visual Basic 6.

I was working on a C# remake. which doesn't do much, just loads a bgdat file (level background object data extracted from the ROM) and lets you view it, zooming in/out. If I use it I'll probably rewrite it, not much was done and my C# skills have vastly improved since then. I haven't worked on it in a while but I might if Tanks keeps pestering me.
