Secret boxers:
     In  Open  Style,  fight  until  you  are  champion  to  access  a
Jack-In-The-Box  boxer.  Defend  the  championship title five times to
access Snake.

     In  Peek-A-Boo,  fight  until you are champion to access Kiki and
Mimi.  Defend  the championship title five times to access Edward King
(the promoter).

     In  Peek-A-Boo,  fight  until you are champion to access Roboxer.
Defend  the  championship  title five times to access Carrie (the girl
that carries the round cards).

Tip:
     When  you  start  carreer  keep  fighting Bill Price and you will
always  win.  He is so weak and you should get an offer from the boxer
at  18th  rank.  I  was  undefeated  and  challenged the champ after 9
matches.
