If you get the source, some of the more interesting bits are the monsters tracking by scent (which I wrote about for the Roguelike News Page), the line of sight code (not because it's helpful, but because whenever I see that macro I cackle evilly), and the dungeon generation code (which probably isn't that helpful either, but had some clever bits).

Note, this project should theoretically be portable to other platforms. It uses a DJGPP-specific method of direct screen access, but all the input and output code is limited to one source file, so grafting in support for Curses, for instance, should be relatively simple.
