Different Dead Pool Fatality
This is a move that you do with Sub-Zero at the dead pool. Beat up your opponent until it says FINISH HIM/HER and then do the first part of the Deep Freeze (F, F, D, HK). This should turn your opponent into a big thing of Ice. Now, instead of doing the uppercut that would shatter them (F, D, F, F, HP) do the stage fatality (hold LP and LK then do a regular uppercut) Now, instead of the regular body going into the dead pool, the chunk of ice will.

Green Ball Trick
Note: These codes don't have to be done in two-player mode, but it is extremely hard to do them against the computer, so just fight against yourself.
Bug: This trick is the easiest. Start a two player game. Select Johnny Cage as one player, Liu Kang as the other. At any time do Johnny Cage's rising shadow uppercut. When he has reached the highest point on the screen, catch him with Liu Kang's bicycle kick. If you do this right, the game will freeze and sometimes Liu Kang's scream will keep repeating at the frozen screen.
Cool new moves: Start a two player game, but this time pick Shang Tsung as both players. During the fight morph into Johnny Cage with player one. Now follow these directions carefully! Move as far into the corner with Johnny as possible, having his back touch the end of the screen. Leave no room! Now repeatedly do his high or low green ball toss. After several times it should disappear. After that do a shadow kick from that location. the process with the econd player Shang Tsung but on the other side of the screen. Once this is done you can let them both morph back. Now the cool part, shoot a fire ball with either Shang Tsung and it will stay frozen in air exactly where you made the green ball disappear. If your opponent hits the frozen projectile he gets hit and loses power like normal. It's unavoidable!
This trick also works with Sub-zero (when morphing), and Liu
