Wonder Boy Cheats

Hold Down-left,1,2 and Start all together while turning on your GameGear. At the title screen, release Start then press it again (while still holding down the other buttons). You will go to the round screen as usual, but as long as you hold 1 and 2 it will stay on this screen. Now relase down-left on the pad, and use Up and Down on the control pad to change the round and level number. You can't get to level 10 though, because you need all the dolls to get there. The furthest you can go is level 9-4.
