Secret Fight with Jade

To fight Jade the arcade way, play single player mode and fight up the latter until the match before the "?" box. Then during that match win one round without touching any other button but low kick. If done successfully, a message will appear telling you that you had just found an undiscovered character from the first tournament and will be sent back to Goro's Lair in Shang Tsung's island to fight Jade, an emerald clad female Edenian assassin that can't be hurt by projectile.

Secret Fight with Noob Saibot

To fight the game's secret fighter, Noob Saibot, you must accumulated a 50 in a row win streak against another player meaning winning two gold MKII icon achievements. After doing so you will get a message that congrats you for the outstanding streak and will be sent to Goro's Lair to fight Noob Saibot, a dark figure resembling Sub-Zero that could blend into the background and had a faster speed.

Note: This trick will only work in version 1.1 of MKII for SNES. Trying this in version 1.0 of MKII for SNES will crash the game. To know if you had v1.1, turn the game on, if you see Sculptor's Software logo before the Acclaim logo or if the game had fight demonstration during attract mode then you had v1.1, if you don't see Sculptor's Software logo upon start-up or the game feature no fight demonstration during attract mode then you got v1.0. Both the Japanese and PAL versions are based on v1.1 so this trick should work on both.
