I'm really tight on money right now and I need to sell my 3DS XL. I have a buyer ready to go but I would like to keep the software on my SD card and my accounts (mii, eshop, ect.) then use them when I can afford to buy a new one (possibly the "new 3DS" when it comes out). What steps if any can I take in order to prepare my 3DS XL for my buyer and allow me to use the software on my SD card and my accounts on a future 3DS console?
I have no choice but to sell it at this point, I have a feeling I will be forced to lose some things because of Nintendo's policies (even though they should have everything stored online somewhere). So any help and advice is welcome.
