This is interesting: the ints are two bytes each, yet the string starts at offset 0x8, implying something in it requires four-byte alignment. Moving char symbol to immediately after string name in the structure should immediately save at least two bytes per instance without having to change the types of any of the members.

Addresses

Address Type Name Information
0x014240A4 std::vector() Notes holds the notes for the map
0x016385DC std::vector() Fort holds data for the current fort, probably has all the forts created so far in the world

Offsets

Notes

Looks like:

struct Note {
  char symbol;
  int foreground;
  int background;
  string name;
  int x;
  int y;
  int z;
}
Offset (+Hex) Type Name Information
0x0 char symbol type ascii char for the symbol to use
0x2 int foreground color foreground color for the note
0x4 int background color background color for the note
0x8 string name text for the note
0x24 int x
0x26 int y
0x28 int z

This is interesting: the ints are two bytes each, yet the string starts at offset 0x8, implying something in it requires four-byte alignment. Moving char symbol to immediately after string name in the structure should immediately save at least two bytes per instance without having to change the types of any of the members.

Forts

Offset (+Hex) Type Name Information
0x38 dword prefix the index for the first part of the fort name
0x38 dword suffix the index for the last part of the fort name

These are indexes to the name vectors, in the stock screen both the dwarven name and the generic name are displayed
