Can I just move micro SD Card?
The battery on my New 3DSXL started to swell so i ordered a new one. Can I just put the microSD from my old one into my new one and be done or will I have to use the old one to do a transfer in the settings? Link_of_Outset - 8 months ago
You have to transfer using system transfer DiduXD (Expert) - 8 months ago
No, each 3DS encrypts its data with a key on the motherboard, and stores tickets (license files) to unlock that data on the motherboard as well. That data is unusable with any other 3DS without doing a system transfer to move the encryption key and tickets to the new system. bungiefan - 8 months ago
