Note Bomber

Note Bomber is a crazy mode when you type in the GH2 Hyperspeed cheat code on the main menu.

Orange, Blue, Orange, Yellow, Orange, Blue, Orange, Yellow (OBOYOBOY)

The first thing you will notice is the text stuttering and changing color. Once you get into the game, you will notice every time you hit a note, it flips (changing your note size to negative). If you set it to the highest note size (in settings) things can get crazy.
