"Speed x4" Modifier
Enter "Yonbai" as your name (in hiragana) to activate the Speed x4 mode. It will make all the notes scroll 4 times faster.
If you cant read the hiragana well, here is the sequence you need to enter it as (all directions are from the upper left corner):
Yo: Down 3 times, Left 1 time
N: Down 4 times, Left 1 time
Ba: Down 6 times, Right 5 times
I: Right 1 time
