This is my favorite game for the 2600.

I built a clone of it for Windows using Direct X in probably 1999/2000. I don't have a Windows machine, but I think Microsoft's obsession with backward compatibility means it probably still works:

Here's the C++ code in all its glory: https://github.com/davetron5000/adventureclone/

It replicates the 2600 game, and adds two new levels (additional castle and maze), and two new (optional) objects, a candle that shows more of the labyrinths, and a shield that prevents the dragons from eating you.
