What the title says.

The goal of this table is to minimize as much as possible the likeliest questions to be asked about NSMB hacking.
Also it is a good opportunity to clean the dust about tutorials that have been long since forgotten.

If there's something else useful to add, feel free to point it out, we ideally want this list to be as complete as possible.


I also give my thanks to  gridatttack for accepting to sticky this thread.

You may could add the thread about the 'Area Overflow Bug'

They are already there, look at the rows with the titles 'Load any area'

Very nice. Note for self: organise this further by putting this on the wiki somehow.

Also: there is that go-to-world map thing in the entrance hex that you could add. I think Dirbaio made a post/thread.

Well, enlighten me please
I don't feel like emulating a detective's work on 4200+ posts.

OP updated with this tutorial from  skawo: http://nsmbhd.net/thread/2971-how-to-edit-sound-sets/

First post updated with 2 tutorials from thereturnofdoritosxD:
_http://nsmbhd.net/thread/2585-useful-stuff-for-nsmb-hacking/ (the exception here as it is not a tutorial per say, but having a list of the likeliest softwares you'll need is equally useful IMO)
_http://nsmbhd.net/thread/2382-how-to-import-and-export-xdelta-patches-tutorial/


Also added the worldmap editor from  ray &  Freeze !

Oh Sharks, maybe this?
http://nsmbhd.net/thread/157-hammer-brothers/#1446

Oh wait, that thread isn't about hacking stuff. Oops.

 MeroMero, what about this thread?
http://nsmbhd.net/thread/2491-how-to-manipulate-the-peach-castle-background-animation-tutorial/
New Super Holiday Bros - Mario Kart GTA San Andreas

Added.

Just one thing though:


 Dirbaio is right, values are 256 and 256, not 263 nor 249, you want to fix that as it can be misleading

The values and the formula are fixed, thanks for reminding me about it.
New Super Holiday Bros - Mario Kart GTA San Andreas

Here was the post:
http://nsmbhd.net/post/38705/

I wasn't dirbaio's, and it is a bit of a mess, but oh well...

Also, dirbaio sent this to me somewhere, I forgot where:
https://dirbaio.net/d/paste/MExoLldg.txt

Oh, that? Well, it's definitely something but I think it needs a little bit polishing before it can be added to the list.
 Baby Bowser will get the credits of course, but further research is recommended to see what can be done with it exactly, this has potential.


Anyway, I dunno what I was thinking but, I wonder why I didn't add this tutorial from Garmichael to the list sooner.
This is a tutorial about how to use NSMB editor in video format.

In the same vein that Pride is the original sin where the 6 other sins stem from, NSMB editor is arguably THE reason NSMB DS hacking is a thing at all.
As such, it gets to be first in the list despite not being the first in alphanumerical order.
The reason is simple, if you can't use NSMB editor, don't even bother with the rest.

As a quintessential tutorial, it is highlighted in red instead of the usual yellow.

I think this should be added.

I don't think this qualify as a likely question though, there are only 2 reported cases as far as I'm aware, and both because of NSMB3.
It's more of an exception than the rule.

Except for SKJmin, no one would even think about modifying the game code, making the answer almost pointless.

Also, for a moral standpoint, wanting to change back the gamecode just so you can open the ROM in NSMBe can be viewed as cheating your way out.

Solution to long known problem of some ncgs and ncls not opening:
LZ compress them! The editor can only open them if they are compressed *facepalm*

The index was updated with several new tutorials:
