The only things to do is turn off any kind of setting that would send base information to Nintendo. Like showing your friends what application you are playing, and turning off Street pass sharing.OK so im thinking of getting a DS and mod it is there anything i should look out for in regards to keeping the console unbanned, So i can still play online ect
It might be easy but you still need a second 3ds console unless you find a donor local friend code seed...which tend to get banned pretty fast as you're not the only one using themJust disable "Show friends what you're playing" and "Sharing of System Information via SpotPass". You should be good from there.
Even if you do get banned, it's ridiculously easy to unban.
