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:

INORGANIC materials
PLANT types
BODY types
BODYGLOSS entries
CREATURE entries
ITEM types
BUILDING types (custom workshops)
ENTITY classes
WORD entries
SYMBOL entries
TRANSLATION entries (languages)
COLOR entries
SHAPE entries
COLOR_PATTERN entries (also includes COLOR entries)
REACTION entries
MATERIAL_TEMPLATE types
TISSUE_TEMPLATE types
BODY_DETAIL_PLAN entries
CREATURE_VARIATION types
INTERACTION types (if save_version > 1372)

World data[edit]

List of 8-byte records
int32 (or List?)
List of int32s -- civ ids?
List of int32s -- unit ids?
List of int32s
List of 8-byte records -- confirm
List of int32s
List of int32s -- confirm
int32 (or List?)
int32 (or List?)

New in 0.34.xx[edit]

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

List of int32s
List of int32s -- book/slab ids?
int32 (or List?)
int32 (or List?)
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):

So... yeah.

Entity POSITION defs[edit]

To be documented.

Region data[edit]

After the last entity def comes the region data, which is divided into blocks.

REGION SAVE block[edit]

This structure appears unchanged from its 40d version.

Type	Name	Description
string	magic	Always "START REGION SAVE"
byte		1
int16		0
int32		1
int32		0
int32		0
byte	has_name	If this is 1, a name struct immediately follows.

REGION DIM SAVE block[edit]

This structure immediately follows the REGION SAVE block, and defines the dimensions of the world map. It also appears to be unchanged from its 40d version.

Type	Name	Description
string	magic	Always "START REGION DIM SAVE"
int16	region_width
int16	region_height
int32		?
int16		?

REGION MAP SAVE block[edit]

This structure immediately follows the REGION DIM SAVE block.

Type	Name	Description
string	magic	Always "START REGION MAP SAVE"
byte	has_block_info	If this is 1, an array of block_info structs follows

Block info array[edit]

The number of elements in the array is always equal to (region_width * region_height).

Type	Name	Description
int32		Always 3? Might be the length value for a byte-list.
byte		?

int16	GeologyID	??

Field names based on info from Mimos.

Minimap array[edit]

The following struct is repeated 8 times, but the last 7 have their minimap_data filled with zeroes.

Type	Name	Description
byte	has_minimap	If this is 1, minimap data follows
[???]	minimap_data	Size is always (((region_width DIV 16) + 1) * (((region_height DIV 16) + 1) * 4) bytes

Unknown data[edit]

Type	Name	Description
int32		????
int32		Always 1?

A List struct immediately follows; each entry has the following form:

Type	Name	Description
int32	index	Starts at 0, increases with each subsequent record.
int32	b	Always 1?
