As many of you might know, it necessary to unscrew the back plate of the New Nintendo 3DS to remove the microSD. If Gateway releases new firmewares, this would mean we have to unscrew the back everytime to replace the launcher.dat. And here comes microSD Management in to play: With this system option it is possible to copy files on the microSD wireless. My question is: Is a internet connection needed to do this or is it possible to do this with some kind of local network (I have no idea of network stuff)? I'm afraid to get the update nag after a few times using microSD management, if a internet connection is needed.
