Will someone please tell me how to do one button fatalities on mk3 and mk2?

Choose Jax and do the ground pound 10 times in a row while fighting Lu Kang in the Subway. You will hear a gong chime and press down and start when this happens to see a computer vs computer match of Motaro vs Shao Khan. This works nearly everytime and I got it from Shawn Nunez which as you know worked on the game for around 500 days before quitting. Thanks!!

please send me Fatalities and moves for all the charters in mortal kombat 3PLEASE!!!!
