To have "freeplay" or unlimited credits, during the story line
press U,U,D,D,R,R,L,L. Do this until you hear a noise. NOTE: You may have to do
this repeatedly until you hear the noise.
Play As Motaro
Pick your player, then pick Wasteland. To pick Wasteland you have to
go to Sonya and press up and start together. Then at the screen right before you
fight, press and hold on to back, low kick, and high kick. Hold on to it until you
become Motaro.
BATTLE WITH CHAMELEON - In one player tournament mode, highlight Kano
and press down and start. Choose champion and Chameleon will be your first match.
Special Endurance Mode
On the Character select screen go to Kano and press Down + Start. If
done correctly, the screen will shake, then when you choose a difficulty you will
have all endurances.
Enable All Options
At the Story Line Screen press HK, LK, Run, LP, HP, HP, HP, LP, LP. If
you enter the code correctly, you'll hear a voice say, "Ah-mah!"
Now go to the Options Screen. Here you can open up the now available
red and blue question mark icons. You now have the ability to have free play, two
secret characters (Khameleon and Smoke), and many other options.
Play as Shao Kahn
Select any character and when you are in either Pit 3 or the rooftop
stage (before the round tarts), press and hold D+HP+LP. You'll see an explosion
and Shao Kahn will replace your character.
If you win, however, the original character you picked will be your opponent
for the rest of the game.
Stage Select
At the character select screen go to Sonya and press Up + Start at the
same time. Then, after you select your character, you will get a stage select menu.
