I bought a Donkey Kong Complete Edition repro from RetroUSB a while back and it plays wonderfully in my NES toaster.

Funny nobody brought up this thread yet. I certainly don't want to be the one to bump it with my first post on Digital Press:

As late as 2009, people were still talking about whether or not a true-to-the-original console port existed, and this is as good as it gets. As to whether this game was a hack or an unreleased prototype, I still have the feeling that Nintendo couldn't be bothered to entirely reprogram a 20+ years old game from scratch. I imagine that at some point during the NES lifespan, Nintendo had the completed code for a complete version of the game, and decided it wasn't worth releasing.

Aswald claimed he visited a friend's house in the late 1990's and played a completed version of NES Donkey Kong with all four levels intact.

I just can't help but wonder if his friend was sitting on a Holy Grail Donkey Kong proto, or if it was just a normal copy...
