universal updater. found some really neat apps there

Universal updater, FTPd, Juxt, Wumiibo

Anemone. I love all the themes you can get.

definitely FTPd! I pretty much use my 3DS as an ipod/mp3 player and it's incredibly inconvienient to take off the back to get the microSD card every time I want to add new music, so being able to manage my microSD wirelessly is a GODSEND

ctrmus on 3ds, bloopair on wii u
