Despite the fact that the game is older than me, apparently there are still some secrets to be found in the original Donkey Kong. Over at the Cutting Room wiki, a user has discovered that there were two pieces of music buried in Donkey Kong’s code, that were never available to the public.
I was just checking this out on my FreedomPop LTE with my iPad. It’s actually really cool, because you can hear that both themes were used in later Donkey Kong games. Which almost makes them a developer inside joke.
Nothing groundbreaking, world shattering, or necessarily remarkable. But a cool find for a game that’s been out for more than 33 years.
