Hello. Im new here so excuse me if these questions have already been answered. First of all, does the trick with Gameshark 2 really work. And if it does, does it play games that were downloaded from the internet or do u actually need the disc. Secondly, does the Gameshark work with Japanese games. And lastly, I heard somewhere that Mod Chips screw up your PS2. Is that true or does that only happen if you do it wrong.
