Hello, Emuparadisers!

I have a question that haunts me whenever I download a ROM.

That question is "is it ripped?"

I don't like ripped games unless that game's lines are cheesy like this:
"Here's a lockpick. It might be handy if you, the master of unlocking, take it with you."

I can smell the cheese already....

So, how do I know if the game is ripped?
