On one of the "Endurance" or boss squares play the game but lose. Right before your
opponent kills you, press Start on the second controller. At the Mortal Kombat screen,
press Start on the first controller. Choose a character and start a game. When you play
you will move above that square. This sometimes works on normal players but sometimes it
doesn't. 

  Note: This trick always works if you select Shao Kahn. You will then play against
several different characters endlessly. As a bonus, every time they win they will do a
finishing move on you.

Plug in a second controller, but play a one-player game. When you lose, hold Down on both
controllers and your opponent will kill you with a fatality or a brutality.

At the begining when it says start game and options press a,c,up,b,up,b,a and down.Then
youl hear shang sung's voice say excellent.

Select the robot Smoke on character select screen. Then, before the fight screen comes up,
hold High Punch + Low Punch + High Kick + Low Kick. Continue to hold these until Shao Kahn
announces the round. (A six-button controller might help...)

B,A,Down,Left,A,Down,C,Right,Up,Down (at START/OPTIONS menu).

Note: a six-button controller is needed to activate this code.

  Enable the cheat menu and select "play hidden game". While the intro screen is running
hold (X+A+Z+C) . Hold this down until the game starts. You should know the code has
worked if you hear a firing sound and see no laser fire on screen. you know have 8 lives
.
