Insert your coin(s), then hold Left Console+ Right Console and press Select to start the game. A menu with "Single", "Versus", and "Double"options will appear.
Note: After inserting coin(s) for two players, hold Left Console+ Right Console and press Select on player one'sside to start the game. Then press Select on player two'sside. This alters the hidden options to "Verses" or "Double".
Press Up, Down, Up, Downat the song or difficulty selection screen for hidden mode. Repeatthis code again for sudden mode. Repeat this code a third timefor stealth mode.
Press Left(8) at the song or difficulty selectionscreen.
Just as you select or song and/or diffculty, you can enter the following codes into the game to make the game easier or harder for yourself. None of the codes work on the beginner levels, but if you select another difficulty after, then the codes will still be active. At the moment I dont know of any master code to cancel all of them.
U = Up arrow on stage
D = Down arrow on stage
L = Left arrow on stage
R = Right arrow on stage
GL = Left arrow next to Select Button
GR = Right arror next to Select Button
S = Select Button
(Insert one credit) Hold GL&GR while pressing S when you start the game will bring up a hidden menu with ''Single, Verses or Double''. Single places it into normal one player mode, Verses lets you play 1 song with 2 players, Double is where a single player uses both pads for one song.
(Insert two credits) Hold GL&GR while pressing S, this will bring up the hidden menu, then press the S on the other side, so if you used player 1 to select the first time, use the player 2 select key. This changes the menu to ''Verses or Double'' Verses is normal verses mode, no changes. Double is the single player using both pads, but you get the same amount of songs as you would get in single player single mode.
These cheats will work in any mode (double or single) except the ones with the (*).
