Decoding scheme for the map (patch for 2.0)
The map has a size of 88 squares horizontal and 68
squares vertical plus one square edging around. Each byte of the saved map
file contains information for two map squares as two hex digits. Each
digit has one of the five values 0 to 5 (incl.) with the meaning:
0 1=city, 2=my city, 3=land, 4=enemy city, 5=border |
