2. Hold down start and press A or B button.

Here is the details about Beginner Mode(submitted by Squints):
1) Regardless of what character you choose, the entrance pose involves a bow to the opponent.
2) Blocking is automatic. You can leave the joystick neutral and unless its an unblockable move, you character will automatically block it.
3) Hits are not as strong. It seems like your hits only take 1/2 to 3/4 as much damage as usual.
4) Takes a lot longer to get POW up. Like #3 it seems like your blocked attacks or hits taken only increase your POW 1/2 to 3/4 as much as usual.
5) When you've already lost 2 rounds, and you have less than 1/4 of your energy left, if your POW meter is at MAX, the computer automatically activates the Rage Eruption for you without you pressing ABC.

Everything else remains the same as far as combos, Rage Eruptions (except for #5), and Special POW moves.
