Will this tool help me accomplish my life long dream of having every 3ds game in existence on one console and one sd card ;o;

... I'm pretty much sure you can accomplish that without the need of this tool. The use of an EmuNAND is not mandatory nowadays.

That's right, but to have them all as icons you only get 300 squares. More emunands means more squares!

I suppose you're right, then. In that case, yes, this tool may come in handy for you, as long as the CFW you're using supports more than one EmuNAND (CakesFW does).

I use emunand9 format sdcard
then use 3ds-multinand_v1.61 inject 2 nand
I use luma
but it can only recognize 1 emunand
for example
I inject nandA in 1，nandB in 2
luma recongnize 1（nandA）
if I inject nandB in1，nandA in 2
luma recongnize 1（nandB）
what is the problem

by the way
these 2 nand backup by D9 named nandmini
O3DS both nand size 943MB

Luma3DS probably isn't compatible with multiple EmuNAND/FAT32 layouts. It most likely just looks for the second EmuNAND at a fixed offset (like 0x40000000 + 512 or 0x40000000 + NAND size for Old 3DS; 0x80000000 + 512 or 0x80000000 + NAND size for New 3DS) and calls it a day.

I found
https://github.com/AuroraWright/Luma3DS/blob/master/source/emunand.h
define NCSD_MAGIC 0x4453434E
your 3ds-multinand.h
define NCSD_MAGIC 0x4E435344

is this a problem?

Not at all. The bytes are just swapped in the Luma3DS source code, but that's because because the ARM architecture (used by 3DS) works with Little Endian. The x86 architecture used by PCs does, too, but I perform a 32-bit byteswap on the magic word to convert it from Big Endian to Little Endian before doing the comparison. 0x4E435344 ("NCSD" in ASCII/ANSI) represents the "natural" order, or so to say.

finally I done
1.Open the command line and run diskpart
2.list disk (my SD is disk 2)
3.Select Disk 2
4.List Partition
5.Select Partition 1
6.Delete Partition
7.Create Partition primary offset=2097152
8.format
9.exit
10.bbcopy.exe bs=512 offs=1 ofd=2 if=nand1.bin
11.bbcopy.exe bs=512 offs=2097153 ofd=2 if=nand2.bin

That's really overkill... Specially considering I'm working on it.

lol
it looks other gays can do this easy way in future

p.s. interesting things is my eurnand do not have nintendo zone，usanand fine
I choose region Australia in eurnand
I am not sure is this the problem

Well, there was essentially no need to modify the SD card layout to begin with. Luma3DS just needed a quick update, that's all.

How about manually installing the Nintendo Zone title?

EDIT: Here's a test build of Luma3DS with my changes: https://mega.nz/#!lApk2YqJ!E-ZXGRVzjdhuQ9kIzQuVECppiyCLkMqXXAgL67OjjuE.

 

[srwgin]

when I use fbi check title it has eur nz title
so I try run nz in usanand region set us hawaii
it say the service has been discontinued
I am not sure is this region change problem

p.s. I am not care it XD

 

[the MCDO]

i am a long time gateway user but just installed arm9loaderhax to one of my O3ds xl. what i have is 11 system nand lumas(was my gateway emunand) , have my 9.2 reformatted gateway emunand set to Down on boot. everything is great "600 total icon limit" but would love to boot a rednand as a vc inject emunand 300 more icon. question is how do i create and boot this rednand?

 

[Deathbot64]

i cant get to different emunands working on a 64gb but they both work fine on a 32gb? any advice?

 

[the MCDO]

So took a while but i got it to work my 256 gb sd card is set up with Luma3ds on system nand (was my old gateway emunand) dsi gba games installed on it. Gateway Emunand is set on the first emunand by holding L+up only way it boots. emunands 2 3 and 4 are rednands and boot with L+right L+down L+left respectfully. VC Heaven is here. Thanks for the emunand creator DARKMATTERCORE

 

[Real.96]

Glad you came back! Hope everything is ok now

 

[OwnHeart]

Hmm this sounds interesting I will give this a go. Thanks mate

 

[Lucas154]

someone can help me? when i click on Start Format and choose emunand.bin (from my Extract NAND from old SD) this window appears, when i say sim(yes), the new SD gets corrupted and I have to format again

 

[GuyInDogSuit]

This worked great for me. Even though I had to separately back up my SD card files and then copy them to the new one, it was easier than the other method pinned in the CFW/Flashcart section.
