Last Bronx Cheats (PC)

Just hold start when selecting the character.

Complete the game in PC mode under the hard difficulty level.

There are two ways to taunt. Tapping repeatedly on the
  guard button is one way (the frustrating way) or you
  could do this (when facing left): down, down+left, left and start button.

To use Redeye, finish the game with hardest
  difficulty in PC mode. Redeye will appear when you press
  up in the character select screen.

One of the cool features in Last Bronx is to be able to irritate your opponent by taunting
him but usually your butt get kicked before you could taunt him.

When a character finishes the game there will be short
  replays of the character with the people he wasted. Press and hold any button during the
replay of you and Redeye (arcade mode, or the last character in PC mode) to hear a message
from your character. What does this message
  have to do with anything? I have no idea !

On the character selection screen,highlight a fighter. Then, press[Start]thirteen times,
hold that key down on the last time it is pressed and hold[Block] simultanously. Now keep
both buttons held until the loading screen appears. (They get the moat funneist weapons
you ever seen.)
