Darklands world map
Files with this format: "darkland.map".

the dynamically generated locations

The map is constructed from tiles contained in two .pic files:
"mapicons.pic" and "mapicon2.pic".

Map data.

This data is RLE compressed: each byte represents 1-7 map tiles.
-
The top three bits are the repeat count,
and are always at least one (
001xxxxx).
-
The next bit is the palette set:
0 for "mapicons.pic",
1 for "mapicon2.pic".
-
The four least bits indicate which row the tile comes from in the palette set.
-
Which column the map tile comes from depends on the four diagonally adjacent tiles:
the 1's bit comes from the northwest tile's row's 8's bit;
the 2's bit comes from the northeast tile's row's 4's bit;
the 4's bit comes from the southwest tile's row's 2's bit;
the 8's bit comes from the southeast tile's row's 1's bit.
