Hi guys. I just want to upgrade my SD card to 128gb (already bought it). After looking for a way to move files, I'm so confused. Being told that just simply doing copy-paste from old to new one (after formating, of course), I found that guide what is much more complicated.
So what should I do for the best? Thanks so much for your help.
If you do not have a RedNAND/emuNAND: You'll first need to format your new SD card. You'll need to format the new SD card as FAT32 with 32KB clusters. Do do so, you can either use guiformat on a Windows computer, or using GodMode9 from Sighax/Boot9Strap. You can load GodMode9 by holding up on the d-pad on boot if you followed the Plailect Guide. If you don't have GodMode9, get Godmode9, copy GodMode9.firm from the GodMode9 .zip to the /luma/payloads/ folder on your SD card, rename GodMode9.firm to start_GodMode9.bin, put your SD back into your 3DS, and hold start to boot into GodMode9. From there, you'll want to unmount your old SD card using the menu option. From there, insert your new SD card and press the home button. A menu will appear. Select "SD Format Options" and select to format the card with no emuNAND, FAT32, and with 32KB clusters. After the formatting is complete, you can power off your 3DS from GodMode9. Do NOT boot the 3DS to the home menu with the new card before copying the files, else you will end up with multiple ID1 folders and your data from the previous card won't show up. Then just copy everything on the old SD card (including the Nintendo 3DS folder) to your new SD card.
If you have a RedNAND/emuNAND (if you don't know what a RedNAND/emuNAND is, you don't have one): Use Decrypt9 to make a NAND backup of your RedNAND/emuNAND. Then, format your new SD card via GodMode9 or emuNAND9 so that it has a(n) emuNAND/redNAND partition. Pick the one you are using on your old SD card. If you have a redNAND, format your SD for redNAND, or vice versa. Then, copy that backup, boot.firm (if you have sighax/Boot9Strap), arm9loaderhax.bin (if you have A9LH), or the /3ds/ folder and boot.3dsx (if you have 9.2 sysNAND), and the /luma/ folder to the new SD card. Boot Decrypt9 from Sighax/Boot9Strap (or the Homebrew Launcher on 9.2 sysNAND) and use it to flash the emuNAND/redNAND NAND backup to the emuNAND/redNAND of the new SD card. After that's finished, then copy the rest of the files from the old SD card, including the Nintendo 3DS folder, to the new SD card.
