The seventh offline tournament for Heroes of Might and Magic I, "Rivers End-not".

I'm playing. I gave it a quick run-through. I'll have to rack my brains for optimization. Hope there's enough time.

In Heroes 4, there's a wonderful cheat to create *.bmp from the game map. Is there a way to do something similar with Heroes 1 maps? I'm a complete noob in Photoshop, but the need to have the entire field in front of my eyes arises on such maps.
