Recently I got a redeem code for Donkey Kong:Country Returns. Unfortunately I was unable to download the game due to a lack of space on my 2GB SD card in my 3DS system. To prevent further problems with space, I would like to get a new SD card, maybe an 8GB or 16GB one, rather than clearing space on the current one. So my question is: if i get a new SD card and use that as my main one, will all my data of my games be lost? What else would I lose if I did that? Would I need to transfer anything from SD cards? If so, how?
Thank you
