Personally I don't flip nor get mad. I like it when a hacker come. You never know what you get.
Because a few nights ago, we were playing Block Fort and
DS Battle stages on wifi.
What made it more interesting, everything was in mirror mode and we were on teams.
Some are good hackers to extend wifi experience and some are ••••••bags that put that stupid blue shell cheat and freeze your game.
It all depends.
