I normally don't talk about hacking because all my friends are such noobs, and they're always want me to buy a flashcart for them and set it up and everything. I get really pissed off talking to people that know nothing about video games/hacking/computers and are trying to act like they do.
I tell all my friends if they ask me, "Go look it up online. Buy the thing yourself, and figure it out by yourself. Just like I did." Because I can't stand helping them when the just mess everything up.
With pirating, I normally get games months before people. With Pokemon Black and White, everyone at school is freaking out, and when they ask me what version I got, I just say, "Neither, I beat the game six months ago." I'm open with it if someone asks me, but I normally don't talk about video games at my own will.
