At the title screen, hold Up and B, then press Start. A kangaroo named Roo will now be available at the character select screen.

To select Ash, defeat him, then hold A on Controller 1. After losing all of your lives, you select to continue and you can choose Ash as your character.

Press C to select a player, then quickly hold A and sweep the D-pad in a clockwise circle until Axel appears. Then press A.

Note: This cheat is very hard to get working.

Hold Down+C on controller 2 as you enter 2 PLAYER mode with controller 1.

When playing as Shiva, you can hit the opponent over and over again until they die without them being able to escape you by pressing Z on a 6 button pad or B and C together on a 3 button one over and over again. This will work on any opponent apart from the ones that can block and the bosses (excluding Jet)

When you fight the clown and Roo, defeat the clown first and Roo should hop away off the screen. When you lose all your lives and continue, cycle through the characters and Roo will now be available.
