Then go up to your opponent while hes not moving. then use the move:(Hold Block) Back, Back, Back, Run
you will pull the character and a saw will hit him. the reason why this is a glitch is because your character is not supposed to move when your doing the saw move.
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 should now have 8 lives.
You need a 6 button controller for this to work though.
Press the following buttons at the start/options menu: B, A, Down, Left, A, Down, C, Right, Up, Down.
On the start screen press:
C, Right, A, Left, A, Up, C, Right, A, Left, A, Up
You can now play as Smoke, Motaro and Shao Kahn.
Motaro kicked your ass and you don`t have any credits more? No problem, just type on the start screen the following code: a,c,up,b,up,b,a,down
