It's a combo of the first and second DJMAXPortable games, right? One of my friends from Korea has both of them, and has been playing the second one for like 6 months and is beastly at it. I think I'd fail within the first 30 seconds...

See he's playing the game on 2.5x speed and playing on hard with 6 buttons.

I'm playing on 1.5x on easy with four buttons.

what is the fastest + most buttons level?
