WORLD.DAT files contain data for worlds in which no adventurer or fortress is currently active.

File structure[edit]

World header[edit]

This immediately follows the save header:

Type Name Description
int16 Unknown Always 0?
int32 Unk1
int32 Unk2
int32 Unk3
int32 Unk4 Max civ ID?
int32 Unk5 Max unit ID?
int32 Unk6
int32 Unk7
int32 Unk8
int32 Unk9 Max hist. fig. ID?
int32 Unk10 Max event ID?
int32 Unk11
int32 Unk12
int32 Unk13
int32 Unk14
int32 Unk15
int32 Unk16
int32 Unk17
int32 Unk18
int32 Unk19
int32 Unk20
int32 Unk21
int32 Unk22
int32 Unk23
byte has_name If this is 1, a name struct immediately follows.
Type Name Description
byte Immediately follows the name struct.
int16 ?
int32 ?
int32 ?
int32 ?
String WorldName The full world name in whatever language.

Immediately after the world name come the generated raws and string table.

Generated raws[edit]

Generated raws are stored in a List of string-lists; each string-list is a List of String structures which contain the raw tags. There may be multiple sections of generated raws, depending on version; in the order they appear in the file, these are:

§ save_version Contents
1. > 1362 MATERIAL raws
2. >= 1400 ITEM raws
3. >= 1287 CREATURE raws
4. > 1362 INTERACTION raws

String tables[edit]

The string tables enumerate all the raw section names used by the save.

Each section is a List of String structures containing the name of a raw object; there are a total of 19 or 20 sections, depending on version:

  1. INORGANIC materials
  2. PLANT types
  3. BODY types
  4. BODYGLOSS entries
  5. CREATURE entries
  6. ITEM types
  7. BUILDING types (custom workshops)
  8. ENTITY classes
  9. WORD entries
  10. SYMBOL entries
  11. TRANSLATION entries (languages)
  12. COLOR entries
  13. SHAPE entries
  14. COLOR_PATTERN entries (also includes COLOR entries)
  15. REACTION entries
  16. MATERIAL_TEMPLATE types
  17. TISSUE_TEMPLATE types
  18. BODY_DETAIL_PLAN entries
  19. CREATURE_VARIATION types
  20. INTERACTION types (if save_version > 1372)

World data[edit]

  1. List of 8-byte records
  2. int32 (or List?)
  3. List of int32s -- civ ids?
  4. List of int32s -- unit ids?
  5. List of int32s
  6. List of 8-byte records -- confirm
  7. List of int32s
  8. List of int32s -- confirm
  9. int32 (or List?)
  10. int32 (or List?)

New in 0.34.xx[edit]

These are only present if the save version is 1372 or greater.

  1. List of int32s
  2. List of int32s -- book/slab ids?
  3. int32 (or List?)
  4. int32 (or List?)
  5. int32 (or List?)
Book defs[edit]
Type Name Description
bytes Generally 89? bytes for slabs, 129-133 bytes for books?
string title Name of the book/slab/letter.
int32 Only present in slabs?
int16 Only present in slabs?

Entity defs[edit]

Type Name Description
int16 EntityType? ?
int32 EntityID
String EntityClass Raw section in entity_*.txt
int16 ?
int16 ?
int32 NextEntityID? Probably wrong
int16 ShortListSize? Flags? Number of int16s which follow. Commonly zero. Could be bit flags?
[int32?] ? Optional. Appears only if above is = 2? ‼Science‼ doesn't know!
byte has_name If this is 1, a name struct immediately follows.
Type Name Description
[int32?] Optional. Seems to only appear in saves with version of 1341 or less when the entity has no name.
int16 CreatureType An index into the CREATURE stringlist/vector.
int16 ?
int16 ?

Next up, we have the confusing bit: a tangled mess of roughly 8 bajillion List structs, often in pairs, with record sizes that vary according to a convoluted schedule, which may or may not based on a combination of:

  • the hexagrams of the I Ching
  • Martian lunar cycles
  • the migratory patterns of Mesonychoteuthis hamiltoni
  • chord progression in Welsh hip-hop


Anyway, here's my attempt at automagically parsing the struct (hex dumps manually cleaned of funky gibberish): 

Reading .DAT header:
 save_version  = 1354
 is_compressed = 0
