I was just wondering if anyone had problems running this game on the PS2. My guess is that it is probably my disc (which doesn't show any visible scratches or smudges on it). I've tried changing all the playstation driver options from standard disc speed and standard texture mapping, to fast disc speed smooth texture mapping, but the game still freezes after it loads the warning about graphic images and Konami logo. Is it my disc or have other people experienced compatibility issues with this game?
