really big games

I spoke too soon. When I renamed the file .txt it changed the file type from MAP File to Text Document or some such. So the game will not recognize it. I then used win explorer help File Types adding to add the new file type MAP File with a function of save game to the list attached to application Space Empires IV. It now recognizes MAP File and this attachment is the new hack. On your own computer define the new type THEN try the download, which I will do as soon as this Posts.
