Cyber: German is cool. I speak a little bit. And just use a random quote from Chrono Trigger/Cross. Nobody really cares. They'll just be like, "Hmm, that's an interesting quote. Why'd you choose that?" and you could just say you closed your eyes, scrolled through the script, and picked it out.
ClayAkame: They can arrest you if they want to. However, depending on how many ROMs you have, they may not fine you or anything. It's similar to shoplifting: where I live, if you steal $100 or more of merchandise, they consider it a felony hands down, you can't get out. Anything less, and they can consider it a felony, but they won't always. Some places don't press charges if it's your first time. In the same sense, if they find two or three ROMs on your computer, they won't care. But 1,000+... they might have a problem.
And I'm also ending the stupid ROM discussion right here. Anybody else mention anything about ROMs, I will find out where you live and make you die a most painful death, preferably by making you listen to some 50 Cent. Stick to the avatar/signature topic.
