Cheat mode:
Pause game play and press Square(2), Circle(2), L1, R1. A sound will
confirm this portion of the code. Then, press L1 + L2 + R1 + R2. The
"Ball Cannon" (set pitch physics) and "Game State" (edit game
parameters) options will now be unlocked.

Note: After using the "Game State" and "Ball Cannon" cheats, if you
do not save soon afterwards, your game may freeze.

Fights:
Hold Square after your batter is beaned and he will charge the
pitcher and start a fight. Your player will be ejected.

Glitch: Getting beaned:
Sometimes if your batter is beaned, he will not be allowed to go to
first base
