Initiative: EA game. "Grow that Nub!"

I believe you are correct, that you only need the image of the map. And, yes, you do need a means to unzip to get it out of the file linked by Kungfoo above.

The key part though, as far as getting the game launched smoothly, is to create your pretender with the "Conceptual Balance Complete 1.92 - Ettin Fixed" mod enabled and that mod only.

Having the map image is necessary only once you try to view your first turn.
