There have been people saying both things about the screen. But the most I\'ve heard, is that its a lot better than the GBC\'s (larger, more colorful, etc).
Me? I\'ve already imported/pre-ordered one and am waiting for mine to come in the mail (anyday now) along with F-Zero (Mario Kart Advance later. Y\'know, stuff that isn\'t very Jap-text heavy. I do know a lot of Japanese, though)
