Hacking Changing SD Cards

[Ziefer846]

Hi all, I currently have the original 4gb sd card running RXtools (4.2 sysnand and 9.8 emunand). I have a few cia files installed along with BigBlueMenu. My 32 gb sd card just came in. What is the best way to transfer everything, including the emunand to my new sd card? Also, what will I lose if I do a fresh emunand format on the new sd card and just copy all the files over? I'm guessing I'll have to update the emunand firmware again.

Download emuNANDTool_1.0.3 to extract your emunand.

Inject it to the new card, then just copy paste everything over.

That tut is obsolete since emunand tool got updated.

Steps using emunand tool:
1. Remove old sd card for the 3ds
2. Insert new SD into 3ds
3. Format emunand on the new SD
4. remove the new SD from the 3ds

Now, the rest of these steps take place on your PC

5. insert Old SD
6. Copy contents to a folder
7. open emunand tool and backup emunand
8. remove old SD and insert the new one
9. copy contents of that folder to the new SD
10. inject the emunand we extracted earlier (using emunand tool)

Thanks! Are there more specific steps when it comes to extracting the emunand using the tool? How exactly do we inject it?

The tool has buttons, one labeled extract, another labeled inject

Would that technically be step 1.5? You remove the old sd card and then use the tool to extract?

I have it as step 7, with the old SD in your pc, extract the emunand

And in order to format emunand on the new sd card, would i only need the gateway launcher.dat?

Ah okay, I didnt realize backup was the same thing as extract, thanks!

Also, is it necessary to format the sd card to fat32 beforehand?

My instructions were vague
You can use whatever to format emunand, wether you choose MT's launcher.dat, Gw's launcher.dat, and I don't know if Rxtools has a format option, I've never used it

Also, is it necessary to format the sd card to fat32 beforehand?

No, when you format emunand with the new SD in the 3ds it creates the emunand partition and formats the card in fat32

If i extract and inject the emunand, will it retain the firmware or will I have to update it again?

The emunand is the whole emulated nand (Yes, it contians the firmware)
It should be the same version as the emunand you had on the old SD

 

[Ziefer846]

Alright, cool. And if I've backed up sysnand using GW, will that also transfer over when I copy the files from the sd card?

You don't need to restore your sysnand unless you have apps installed to it. The SD card just stores settings for the sysnand, it can be created new or just copy pasted over from the old.
