Over the top violence grabbed headlines, while iconic characters supported a multi-media empire -- but a history of secrets and mystery made Mortal Kombat the stuff of arcade legends. Some rumors were never true and others not so secret, but thanks to YourMKArcadeResource, one of the great mysteries of over twenty years has been brought back and uncovered!

Laid bare, the "EJB Menu" is found in at least the first three Mortal Kombat arcade games. Once input, the menu allows the user to access a variety of diagnostic menu functions, including leader board edits and character ending sequences.

As explained in YourMKArcadeResource's video [embedded above], initiating the EJB Menu requires a lengthy string of alternating block inputs by players 1 & 2:

Mortal Kombat EJB Menu Input:
P1 (5x), P2 (10x), P1 (x2), P2 (x1), P1 (x2), P2 (x3), P1 (x4)

Mortal Kombat II EJB Menu Input:
P1 (5x), P2 (10x), P1 (2x), P2 (8x), P1 (2x)

Mortal Kombat 3 EJB Menu Input:
P1 (5x), P2 (10x), P1 (3x), P2 (1x), P1 (2x), P2 (2x), P1 (3x), P2 (4x)

The discovery is believed to be one of the first times the hidden menus have been accessed by fans! It accounts for at least one of the undiscovered secrets series co-creator Ed Boon has often cited.
