Public Domain Version of Donkey Kong Jr 5 Screen release

The 5th screen does not automatically reveal when playing this version.

To make it reveal you must enter the player selection screen and press the controller fire buttons on both sides and hold them while you push the following sequence: 1 - 3 - 2 - 1 - 2 - 1 - 2.

The game will then automatically acknowledge you are playing the 5 screen game. Remember that it only works on the 5 screen public domain version of Donkey Kong Jr.

This all depends of what disk or DDP image file that you are using as this Easter Egg input was shortened and then eventually eliminated altogether as a requirement for the 5th screen to work.

I never saw any mention of who or whom originally found this Easter Egg as well as who or whom hacked it to shorten and then eliminate the need to enter it.
