Below is a detailed map of Castlequest. I believe I have solved all the necessary puzzles, and all the maps are correct. Eventually I hope to discuss the tougher puzzles where you can click on the map, but right now I just want to have posted all the GIFs. These were created via screenshots from NESTICLE, with Paint Shop Pro used to save the graphics from PCX to bitmap, and then I wrote a small C program to cut and collate the far left-side and far right-side pictures. I'm pretty sure everything should be ok, but contact me if something looks goofy, as I managed to flip-flop the left and right sides of a couple of pictures originally.
I have also written a FAQ for this game which you can see at GameFAQs. Link
I am putting the link home here as it may be a bit of trouble to wade through stuff below.
