I was checking out all of the game modes recently and found out that if you play the "8 Player Tournament" by putting in two controllers, then with player 1 choose your favourite character four times and any random characters on the secon controller...
Next, at the start of the fight at the versus screen press RT and B four times on the first controller and RT and A four times on the second controller, this will make it a one hit KO match to quickly get the four matches out of the way, then select the "3" Shao Khan treasure and you be against Noob Saibot

Not sure if this has been noticed before but im just posting it up after just finding it
P.S Good luck with Noob
