"A piece of text in the game's code reads, "By the way, if you like this game, buy it or die." This text is actually an anti-piracy measure that can be activated by using a Seagallop Ferry when playing a dumped ROM of the game. Several ROM dumpers have verified that this was not inserted by a third party." About Fire Red/Leaf Green
