which is better? r4 or m3, you help me decide. i know r4 has a cool ipod clone, but mp3s ar kinda weak on a ds but the concept is cool. i own a r4 but have the oppotunity to get a m3, does an m3 hve a version of an ipod clone? any clitches or lag on game loading? tell me how you feel, thanks and play on.
