i've just copied my first PS2 game using nero. all the files transferred onto the blank dvd-r but my playstation will not play the copied game. i've seen that you have to get your ps2 chipped. Do you REALLY have to get your playstaion2 chipped/modded or should an exact copy of an original game play on a standard un-modded PS2? Also what is the best media type to use? i put my copy onto a dvd-r but can a cd-r be used and if so does it work just as well?
