User 387 So I first checked if the rom could play multiplayer with another ds, and it worked perfectly. Then I inserted a custom track, but then it didn't work ( WHen downloading it freezes on the nintendo logo). Is there a way to edit the downloadable content for multiplayer? Is it possible?

MKGirlism Certain tracks have a separate file for Download Play, like "cross_course" for example.
You can recognise them by the extra "D" suffix in the filename, which in this case becomes "cross_courseD".

You might try replacing this one as well.
However, I'm not very sure, if I can be honest.
It has been a very long time I've done any active MKDS Hacking.

PabloMK7 You can't play modified roms in download play, the DS checks if the rom is valid and signed by nintendo. If it isn't, it will freeze in the logo.

Swiftie Luma All i know is that both people have to have the game so it works.

Otherwise it won and will freeze. This is for roms only , the original cartridge does not have this issue obviously.

SGC Yellow No, it won't work because data in the header changes from modifications to the ROM, and this voids Nintendo's signature.
Only Multi-Cart Play is possible, for now.

Louiskovski It is possible! But it's bullshit :/
With NSMBDSe, you can modify nds roms without causing the other ds to hang if downloading. You have to use an untouched and clean MKDS rom. As soon as you open the rom, you have to go to Tools and enable DLP-friendly mode. Now you can replace the courses, but now the problem: The course you want to add MUST HAVE THE SAME FILESIZE OR LESS, then the original course you want to replace. The same is with every other file! The other DS also may crash, when a specific object is on the course. A goomba crashes the other DS, if you kill one, for example.
There is also the option to use a modification of the DS firmware that downloads everything, but NEVER USE IT ON A 3DS!!!! I unfortunately tried that, and the ds fw from my 3ds got corrupted, and now the touch screen doesn't work anymore and it's everytime in english (it should be in german).

Is the first method safe for 3ds?

MKGirlism All DS software, which also includes Flash Cards, run in DS Mode on a 3DS.
Therefore, the 3DS will emulate the exact environment of the DS, and thus, it will work the same.

If you mean the "never use it on a 3DS" part, this firmware flashing stuff will only work on the first DS model.
DS Lite might brick, and anything newer will brick.
