Donkey Kong (Atari 8-bit family)
This game has hidden developer credits.
A port of Donkey Kong on an Atari computer. Mmm hmm...
Set a new high score whose ten thousands and thousands digits are 33, 37, 73, or 77, then lose your last life by falling. Afterward, set the game difficulty to 4 by pressing Option three times, then wait through the end of the demo where Donkey Kong jumps across the screen. Upon returning to the title screen, programmer Landon Dyer's initials (LMD) will appear.
