How to move Games, Saves, Themes, and Emunand to a new SD card
I recommend trying the first method first. If you get an error using EmuNAND Tool, try the second method.
Method 1 using EmuNAND Tool
- Get Emunand Tool (latest version, or version 1.0.1 if you get an error in step 12)
- Insert your old SD card in your PC
- Open Emunand Tool and select "Extract EmuNAND"
- Save it somewhere on your PC (as [EmuNAND firmware version] emunand.bin if you want)
- Backup all your SD card files to your PC
- Eject your old SD card
- Put EmuNAND9's launcher.dat on your new SD card
- Launch EmuNAND9 using the web browser in Sysnand (URL: go.gateway-3ds.com)
- Once in EmuNAND9, navigate to Complete EmuNAND Setup. Ignore the starter.bin warning and follow the instructions. Wait for the EmuNAND creation process to finish.
- Turn off your 3DS
- Insert your new SD card in your PC
- Open Emunand Tool and select "Inject NAND to emuNAND"
- Select the emunand.bin you made in step 4 and press OK
- Close Emunand Tool when done - you will know it is done when the buttons are clickable again
- Delete all the files on your new SD card
- Put the SD card files from your backup (from step 5) on your new SD card
- Done, emunand and data (saves, games, etc.) have been transferred to your new SD card!
Method 2 using 3DS Multi EmuNAND Creator
- Get 3DS Multi EmuNAND Creator
- Insert your old SD card in your PC
- Open 3DS Multi EmuNAND Creator with Administrator privileges and select "Extract NAND"
- Save the EmuNAND backup somewhere on your PC (as [EmuNAND firmware version] emunand.bin if you want)
- Wait for the "Operation successfully completed!" message to pop up, then click OK. You now have your EmuNAND backup from your old SD card.
- Backup all your SD card files to your PC
- Close 3DS Multi EmuNAND Creator and eject your old SD card
- Insert your new SD card in your PC
- Open 3DS Multi EmuNAND Creator again
- Under the Format EmuNAND section, make sure that your new SD card is selected, then click "Start Format"
- Select the emunand bin file you made in step 4 and click Open
- Click Yes at the warning to start the process
- Wait for the green bar to reach the end and the "Operation successfully completed!" message to pop up, then press OK
- Close 3DS Multi EmuNAND Creator
- Put the SD card files from your old sd card backup (from step 5) on your new SD card
- Done, emunand and data (saves, games, etc.) have been transferred to your new SD card!
Here is yet another method using partition managers, if the above two methods don't work for you.
