So, I've just gotten into my sky3ds and I have to say it runs really well. However, online play has interested me. I've not played online yet because of seeing reports of bans through public headers or not using a header. So, I've gotta ask. What exactly IS a header? I've done a bit of homework and I kind of get the idea of it. It's like an ID for your 3ds game. Anything else to add onto this or do I basically have the gist? Secondly, how do I get a private header? I've seen that your own games can get you a private header, does it apply to the whole cart then? Also, how do I obtain it from my game? Thanks very much in advance.
