    You won't see anything meaningful over https. It was invented to prevent such man in the middle naughtiness.

    I wouldn't be surprised if Nintendo aren't using HTTPS for most traffic. In-game packets will likely be UDP as well. Depends what you're after really.

    Nintendo has been using HTTPS/SSL since the DS came out. Good luck finding anything without maybe patching a rom.

    People, remember they originally transmitted what amounted to secret data in plaintext in pokemon, a game series which has traditionally had at least some minor cheat frustration in it. They do use HTTPS and other encryption but it is often more for handshakes, logins, payment data and similar things -- encryption is extra load on servers and in the minds of many a game dev there is no sense adding more for no real gain.
    Anyway things like the pokemon stuff (though not pokemon any more really) are about all 3ds network capture is useful for right now. If it amuses you to pull apart some parts of a network protocol though then carry on.

    Anyway it is fairly normal capture for the 3ds. You make sure your wireless network is low enough on security (modern wireless security protocols like WPA2 prevent useful wireless capture for devices on the same network) and capture. If that is not an option (many modern ones have guest network options which you can probably drop back to WEP or even unencrypted) then you have two options.
    1) Run your own access point. Wire your computer into the network, get a wireless card, set it up as an access point, capture from there.
    2) Make sure your computer gets the data. We saw various things here during that pokemon phase. If you have a proper router (you probably don't) you can do things like frame redirection and the like, your home thing probably does not have this though. Others did things with static IP addresses (put you PC as the 3ds gateway and then forward that to the real gateway) and others still did things like ARP poisoning.

    If you go back through that pokemon dumper/editor thread ( http://gbatemp.net/threads/pokémon-x-y-dumper-and-editor.356901/ ) then you will find some info. Again it is of seriously limited use to pokemon but other games might have something still.
