I have no technological expertise at all whatsoever so I apologize up front if this is a stupid question. All of the downloadable titles that I have on my 3DS are taking up too much space. Can I purchase another SD card and transfer all of my downloadable titles to that without effecting anything else for my 3DS? If so, when I want to play one of those titles is it as simple as swapping in that SD card? Does any SD card work or would I need a specific brand (does Nintendo make one)?
