Hint: Defeating Big Riddle: Enable the "Cheat mode" code. Select the

you fight the Big Riddle monster, throw the Batcuffs (Towards,
Towards, C). This will immobilize the enemy, allowing
you to pop him with an Uppercut (Down + A). Repeat
this until the monster is defeated. Do not worry if he regenerates
some of his strength. Just use the Batcuffs and Uppercut pattern.
