So I got New Aventure Island and added it to my flash cart and when to play on my DUO-RX after a game of Street Fighter 2 I left the pad on 6 instead. Well once the game started it skipped a level. Next stage skipped. WTF, I look at my pad it was in 6 button mode. So I went to 2 mode and it didn't skip stages, but click it on and boom next stage. Give it a shot, it is kinda nice for when you have to run in the middle of the game.
