Start a new game and name your character. After you are done go to the
"End" and press these buttons: On controller 2, hold A, B, C and press
Start. On Controller 1 press A, C and Start simultaneously. A new
character will appear. Name the character and another one will appear, etc.
This will go on until you have named every character in the game.
Hold Up and Start on Controller Two, then press RESET. Let go of the
buttons as soon as the Sega logo begins to appear, then hold A and C
on Controller Two. While holding these buttons, select "Continue" and
skip through until the girl's message begins with "Good Luck." Hold A
on Controller One. This takes you to a Battle Test screen, where you can
fight in any of the game's 30 battles.
