Event select: Enter HINGSEN.J as a name at the high score
screen. Then press the function keys to select various events.
Alternatively, enter HINGSEN-J, then press [Delete].
The word "Demo" will appear to confirm correct code
entry. Type -J to change to "Mega Demo" mode.
Note: Another way to enter this code is to wait until the music
stops at the high score screen before proceeding. The sound of
a drum will confirm each correct key press.
