What I did is to put that firmware I linked a few posts ago in a flashcart, and use it to download the game.

On the "guest" DS: Boot the firmware. Go to DS download play and wait for the download.
On the "host" DS: Play NSMB, go to Mario vs Luigi, and select play with another person who doesnt own nsmb.
On the "guest" DS: Accept the download, wait until it loads.

Troubleshooting:

Q: OMG! That custom firmware doesnt work! It hangs when loading!
A: It doesnt work on all flashcarts. For example, it works on a R4SDHC on a NDSL, but doesnt work on a R4I SDHC on a NDSL. Havent tested it on a DSI.

Q: I have two DS's but only one flashcart. Can i use DS download play?
Yes. Use the flashcart to boot the firmware, and once it is loaded you can take it out (the firmware doesnt hang, at least with my flashcart) and use it in the other DS to boot NSMB.

@Cataclysm: It IS possible to move sprites, and move/resize views, what you can't do is add or remove.
The game icon problem is caused by a bug in the editor which will be fixed in next version.

@m64m: Yeah, theoretically it is, but Nintendo doesnt want custom stuff to be played, so he added checksums and digital signatures (i think?) on the latest firmwares, resulting in it not working. That's why it works on older DS's.

@Hiccup: The multiplayer levels are in two different places in the ROM. One is the one you can edit on the editor, on the "course" folder, which is NOT used by the game, and the other is inside the NARC's, which is the one used by the game. That's why you have to copy the level files from the course folder to the narcs.

You can build it yourself now if you really want it

Anyways, what was this topic about again? I'm lost.

^ it's open source, so you can compile the current build.
I think some 3d stuff wouldn't be working if you did that, but I don't think it would be missed.

that web page there's a copy of the DS firmware but converted to a .nds image.

Are you sure that's a good idea? It has the possibility of being really cool or really bad.

Cataclysm, stop asking so many questions.
No new sprites.
No changing the tileset.
Anything else is okay, now stop asking so many already answered questions!

Hey, let me ask you. How much do you know about M vs. L hacking?!?!? I havn't found the answers to these questions on any thread. This "No new sprites.
No changing the tileset.

doesn't answer any of my questions. And not everything works. Springs and vines that come out of ? blocks don't work.
And who told you to tell me to stop asking questions about M vs. L hacking?!?!?

P.S. I already know that adding and removing sprites do not work.

---

How much do I know? I was the one who discovered how to edit the levels and I've been doing it for just under a year, so I know quite a bit. And as long as the block in question doesn't spawn a sprite, it will work. So stop it now plz. Kthxbai.

While I'm here, there's something I found out with the star sprite. You can't add or remove any stars or the level doesn't load. It must either be a checksum, or that each level has an engine to choose one of X stars and if you change it, it can't function. So leave those stars alone.

yeah.

I understand you ask so much questions. It's a pain to test yourself all the blocks, specially if you don't have two ds's (like me ), and you have to send a patch to a friend, have him put it on his flashcart and test it the next day with him, seeing his disappointed face when he sees only a black screen, not understanding why he should have downloaded, applied and copied to his r4 the patch for only a black screen... That's why I havent played much with MvsL hacking...

I think we should compile a list of what works and what doesn't.


=== WORKS ===

OBJECTS: Adding, deleting, resizing, moving, changing type
SPRITES: Moving, changing type and data
VIEWS: Resizing, moving
PROGRESS PATHS: Moving, resizing
ENTRANCES: All. Doors not tested
Vines (NOT the one that comes out of ? block)

=== DOESNT WORK ===
SPRITES: Adding or deleting
STARS: Adding or deleting
? blocks with vine and springboard
Changing sprite sets, backgrounds, tilesets.
Mini pipes.

=== HAVENT TESTED ===
(If someone tests one of these please report if they work or not here.)
Doors
Invisible blocks
Adding views and entrances to them
Adding progress paths for the new views

=== TO BE INVESTIGATED (It's possible but its not clear how) ===
Entrances to other levels.
DS Download Play (seems to depend on your firmware, works on some ds lites or not).
If you report it works or not with your DS, please try to report here when did you buy it, and your firmware version using the pictochat trick: Launch the NDS with an official game inside, go to Pictochat, take it out, see what color the screen turns into.

I also forgot to mention that the mini pipes work but will appear as a white block.

---

Well... That means they dont work. Who would want glitched white blocks in their MvsL levels?
