We have seen reports of what could potentially be the Goro and Noob Codes for the home versions of MK4. However, we have confirmed that there is more to the code. In order to play as Goro or Noob Saibot, you must first enable the cheat menu. This was
originally undiscovered since people had done the last step without knowing that someone had already enabled the cheat menu before. Special thanks to Dharmesh who found out the full routine to play as Goro and Noob Saibot.

Secret Menu N64: At the Options menu, go to Continue Options and then hold BL+RN for about 10 seconds, the cheat menu will reveal itself. Playstation: same as N64 but go to the Vs Screen Enabled option. Characters Goro: Select the Hidden button on the bottom of the select screen, move up 3, and over 1 (to Shinnok's icon) then press RN+BL together. Noob: Select the Hidden button on the bottom of the select screen, move up 2, and over 1 (to Reiko's icon) then press RN+BL together.
