HIDDEN MESSAGE: There is a way to trigger a hidden message
(a security feature perhaps?). It may have something to
do with the connections of the bus sub-board. When triggered,
the message "MADE BY NAMCO" appears, spelled out
in red dots on three horizontal rows, filling the screen.
Hiding spot At the start, go left and up first channel
and stop. Make sure no monsters see you doing
this.
BUG: Kill screen - After level 255 (243rd key), the famous
split screen appears (board 0 - byte rollover
phenomenon).
RUMOR: Its possible (?) to avoid this if your score
at the end of level 254 contains the sequence 255
at any position in your score. Youll then return to
the cherry board, except instead of a cherry in the lower
right corner, there will be a broken key in both lower corners.
None of the monsters will turn blue. Two additional split
screens occur- one the 366th key, and the other somewhere
in the 460s.
