Would I be able to buy any regular SD card and have it work properly in my 3DS, or would I have to purchase a special card from Nintendo? My 3DS XL came with a 4GB card and I was thinking of buying a 16GB for it, larger if I can find one and afford it. Some digital downloads take up a lot of space. Heck one game I considered but decided not to buy would have taken over half the blocks left on the card by itself. It required about 15,000 blocks and I have a little over 26,000 left.
If a standard SD card would work, is there a way to properly copy all info on the old card to the new card? Would it save all streetpass and game saves? When plugging the SD card into my PC I can't figure out what the files are. They all have file names made up of numbers and such and no file extensions. The only file I could view as a picture of myself I took with the 3DS camera. So I'm bascially wondering if I could just copy the files to my PC hard drive then copy them over to a new SD card and have everything work right with the e-shop, game saves, etc.
Any help is appreciated.
