EDIT: The emuNAND Tool has been updated and now works again!

Since right now the emuNAND Tool doesn't work, I've come up with a workaround:

Programs you will need:

• USB Image Tool
• EaseUS Partition Master

Both these programs are free.

PLEASE NOTE: Doing the following method will make a 1:1 copy of the source SD card and put it on the target SD card. It will transfer everything, not just emuNAND.

How to:

1. Plug the source SD card into your PC, this is the card that you want to transfer emuNAND from.
2. Run USB Image Tool
3. Click on the SD card and then "Backup"
4. Remove the source SD Card and replace it with the target SD Card.
5. Click on the new SD card, locate the backup image and then "Restore"
6. Run EaseUS Partition Master and click on "EaseUS Partition Master Free"
7. Right click on the SD card's partition with data on it, it should be in between two Unallocated partitions and choose "Resize/Move Partition"
8. Click on the MIDDLE PARTITION, the one that has the data on it and expand it TO THE RIGHT (VERY IMPORTANT)
9. Click OK
10. Click Apply on the top left, then OK
11. Done!

Important Information:
Currently with Gateway 3.1.0 there's a (visual?)bug with higher capacity microSD cards. When running emuNAND it doesn't show the "GW3D" in settings, before the version number telling you if you're in emuNAND or not, because of this its very risky to update emuNAND.
With my guide you can use a 4gb microSD card (where the visual bug doesn't happen) to format emuNAND, update to the latest firmware and transfer it onto a higher capacity microSD card.

Don't panic! - When the transfer is complete and you run the updated emuNAND on your new 3ds it still wont show the "GW3D" prefix before the version number. It'll just say 9.5.0-22E or something along those lines.

Any questions, feel free to ask

Thanks for your guide. I do have some questions.

1)

Which space/partition is what exactly?

2) I should expand the middle one with the 26,17GB. I leave the 2,00GB alone?

Right click on Fat16 > Resize/Move Partiton, then you click and drag the bar to TO THE RIGHT. Expanding it to the left causes you to delete emuNAND as that's where its stored, you leave the 2gb unallocated alone.

Working for me. Thanks.

Working for me. Tkanks.

No problem, enjoy!

awesome, thx for the tut :o though there is still no GW3D before 9.5.0-23E in emunand but that doesn´t matter.. i´m just happy that it worked

i hope i can do now the system data transfer from my o3ds to n3ds

you should be able to

EDIT: Nvm, i misread the guide. i thought u were supposed to move the fat16 over, but you actually expand it


Is the 2GB supposed to combine with the 26GB partition to make one, big logical partition? I followed this guide and i can get into emunand, but now when i use my SD card on my computer it only recognizes 1.63GB. How do I use the other 26 GB?

I miss something or EmuNand 9.5 works fine in N3ds. I thought the GW team told emunand > 9.3 doesn't work on N3DS ?

They said 9.5 wouldn't work but it does with the new update. I'm thinking they fixed and forgot to add it to their official announcement.

So for a Systemtransfer emuNAND to emuNAND, you first initalise a normal Systemtransfer and when
the 3DSes want the SD-Card swap, you swap the emuNAND patitions?
Did I get this right?

I will also retry to see (had 6000 blocks free, instead of more than 200 000), it wasn't working for me before this tutorial was created but I was moving the FAT16 partition instead of expanding it so it might be the problem.

 

[kirbymaster101]

so what if I want to use my 64gb card on my OG3ds to the N3ds

It worked, thanks.

No, you better use WiFi-transfer.

PS: Der EmuNAND liegt doch auf der SD-Karte. Stürzt das System nicht ab, wenn du die Karten aus dem 3DS herausnimmst?

If i wanna make a backup from my current SD Card and need to use it later on the same SD card, i just need to restore the backup? Do i need EaseUS Partition Master for that?

 

[Leslie White]

I hope GW will release SOON an update to solve this GW3D not showing up with large uSD cards ! I have to use the 4gb which came with the N3DS for now and cannot do the system transfer from my old3ds (more than 4gb files)

No need to use EaseUS Partition Master, just backup/restore.

Hey Zaazu thanks for the tutorial! Do you know any tools that do the same thing but for Mac OS? I only have an SD card reader for my mac, dont have it for my pc. THanks!

He just copied an existing method. You can use dd to make and restore the image, then any partitioning program (e.g. Disk Utility) should be able to resize the data partition.
