The FAQ is very confusing. That's the reason why I don't help there (and I don't want to read all the entries).The FAQ is long, and you will need to read it to find answers. (too bad, I know, searching for answers is a hassle)
It's obviously missing questions and answers too, but users don't feel like helping each others, I'm the only one maintaining that FAQ.
But you get help with the other wiki pages concerning the 3DS/ 3DS flashcards.
