By cheats, I mean fatalities. Hara-kiris. And what ever else I can think of. I will make separate pages for each when I have more time.
Fatalities (MK deception):
After you have beaten an opponent and the announcer yells "Finish Him!" it is time to input a Fatality. Fatlities require a set distance to perform. The distances are:
Close: 1 step away from your dazed opponent
After you are at the required distance press the L trigger to enter the Fatality stance. Then input the fatality code.
After an opponent has beaten you and the anouncer yells "Finish Him!" it is time to input a Hari Kiri. Hari Kiris require no set distance unlike fatalities. To perform one simply put in the code while your character is dazed after losing a battle.
