No. You also need to copy the hidden emunand partition.

 

I recommend you use this tool to extract the emuNAND from your sd card, and inject it into the new one

Does it erase any data?

 

It works on any SD card.

If you don't want to bother with the USB partition then there is another way to do it.

This will follow closely as the same steps as if setting up a new emunand.

Primary SD card will be referred to as Prime. The new SD card will be referred to as Beta.

On Prime you want to run Decrypt9 and backup your emunand.

After your Emunand is backed up copy all files, including the emuNAND.bin, from Prime to a safe location on your computer.

On Beta make sure you can access homebrew and go through with the same steps you did to setup emunand. This will format Beta, but don't worry as after this is done you will copy all of your files from Prime to Beta, including the emuNAND.bin.

Restore the emuNAND.bin with Decrypt9 on Beta.

Congratulations. You just transferred your emunand from one SD card to another.

 

Not on the SD card you're copying from. Everything on the SD card you're copying to will be erased of course.

 

No. Remember the part where I said backup SD card Prime and move it to Beta? This is transferring your saves from one ad card to another.

 

Doing it with your PC is the same.

(and you did a thread for people to ask you questions about 3ds hacking ? Seriously ?)

 

No man can know everything, no man can know nothing.

EDIT: Also wasnt "any" question.

 

It means everyone can learn more...
