Formats identifiers in Fallout

The paper described identifiers FRM- file formats (FRM ID or FID), a prototype identifier (Prototype ID or PID), the script identifier (SID or Script ID), and the sound effects identifier (Sound Code ID) for Fallout. Information about them was obtained in the course of reviewing relevant functions in files Fallout2.exe, Fallout.exe and Mapper2.exe.


Ids are 4-byte numbers representing the objects with which operates Fallout. The exception is the 'Id sound effects' (Sound Code ID), which is the symbol and is the size of 1 byte.

FRM File ID (FID)Edit

In general, FID is a number follows:

 |      |         |                 |                 |                       |  
 |      |         |                 |                 |                       ------------------- Index in LST-file  
 |      |         |                 |                 ------------------------------------------- ID1  
 |      |         |                 ------------------------------------------------------------- ID2  
 |      |         ------------------------------------------------------------------------------- Type of object (ObjType)  
 |      ----------------------------------------------------------------------------------------- ID3
 ------------------------------------------------------------------------------------------------ Unused

Fields' type object and 'Index in list-file' always used, while Fields' ID3 ',' ID2 'and' ID1 'can be ignored depending on the fields' object type' (Table 1.1). Perhaps not used can be any bit.

Table 2.1-use fields ID3, ID2 and ID1

ObjType ID3 ID2 ID1
0x00: items
0x01: critters x x x
0x02: scenery
0x03: walls
0x04: tiles
0x05: misc
0x06: interface
0x07: invent
0x08: heads x x
0x09: backgrnd
0x0A: skilldex

For FID, is not related to the substance of the head and "speak", the name of the file is the appropriate element LST- index file.

Critter FIDEdit

File Name FRM- substance is the following



Root       - root filename (6 characters) 
Suffix1    - first suffix (1 symbol)
Suffix2    - second suffix (1 symbol)
ExtSuffix  - suffix expansion filename (1 symbol) 

Example: Let filename = HAPOWRBA.FR0

Root       - HAPOWR 
Suffix1    - B 
Suffix2    - A 
ExtSuffix  - 0 

In FID substance used in all fields. ID1 defines Suffix1, ID2 - Suffix2, ID3 - ExtSuffix.

IDs have the following meaning:

ID1 - Weapon code-code identifying the type of weapons in the hands of active substance (see "PRO- Format files Fallout2" box Weapon Anim Code).

ID2 - Animation code, the code defines the action produced the substance (see ANIMCOMD.H File).

ID3 - Direction code, the code defines the orientation of the substance in space. Note that .frm files contain animations for all six orientations

When ID2 equal 0x1B (27-ANIM_electrify), 0x1D (29-ANIM_burned_to_nothing), 0x1E (30-ANIM_electrified_to_nothing), 0x37 (55-ANIM_electrify_sf), 0x39 (57-ANIM_burned_to_nothing_sf), 0x3A (58-ANIM_electrified_to_nothing_sf), 0x21 (33-ANIM_fire_dance ), 0x40 (64-called shot interface picture), a change takes place in the Index LST- file. The index is changed to the first number, after facing rows with the root of the file name.


Must replace index 0x62 (98). Look 99 line file critters.lst. There is nmoldd, 11. Accordingly, the revised index will 0x0B (11). Matches between the values ID1, ID2 and Suffix1, Suffix2 in Table 2.2, but between ID3 and ExtSuffix in Table 2.3.

Table 2.2-Match values ID1, ID2 and Suffix1, Suffix2

ID2 ID1 Suffix1 Suffix2 Notes
- ID1 ≥ 0x0B (11) - - Invalid value
0 x26 (38) ≤ ID2 ≤ 0x2F (47) ID1 = 0x00 - - Invalid value
ID1 > 0x00 'd' + (ID1 - 1) 'c' + (ID2 - 38) weapon animations
ID2 = 0x24 (36) - 'c' 'h' stand from prone
ID2 = 0x25 (37) - 'c' 'j' stand from back
ID2 = 0x40 (64) - 'n' 'a' called shot picture
ID2 ≥ 0x30 (48) - 'r' 'a' + (ID2 - 48) single-frame death animations
ID2 ≥ 0x14 (20) - 'b' 'a' + (ID2 - 20) knockdown and death
ID2 = 0x12 (18) ID1 = 0x01 'd' 'm' knife throw
ID1 = 0x04 'g' 'm' spear throw
- 'a' 's' unarmed (i.e., grenades) throw
ID2 = 0x0D (13) ID1 > 0x00 'd' + (ID1 - 1) 'e' dodge (parry)
ID1 = 0x00 'a' 'n' unarmed dodge
ID2 = 0x00 ID1> 0x00 'd' + (ID1 - 1) 'a' stand
ID2 = 0x01 ID1 > 0x00 'd' + (ID1 - 1) 'b' walking
- - 'a' 'a' + ID2 other basic animations
Note: Terms of the top lines of the table took precedence over the terms of the bottom lines

Table 2.3-Match values ID3 and ExtSuffix

ID3 ExtSuffix

0x01 '0 '
0x02 '1 '
0x03 '2 '
0x04 '3 '
0x05 '4 '
0x06 '5 '

Talking head FIDEdit

File Name FRM- head "speaking" is the following

RootSuffix1Suffix2 [Sufix3].frm 


Root	- root filename (5 characters) 
Suffix1	- first suffix (1 symbol) 
Suffix2	- second suffix (1 symbol) 
Suffix3	- third suffix (typically 1 symbol, but theoretically could be more, not required ) 

ID2 defines Suffix1 and Suffix2 and ID1 - Suffix3 (Tables 2.4, 2.5).

Table 2.4-Match values ID2 and Suffix1, Suffix2

ID2 Suffix1 Suffix2
0x00 'g' 'v'
0x01 'g' 'f'
0x02 'g' 'n'
0x03 'n' 'g'
0x04 'n' 'f'
0x05 'n' 'b'
0x06 'b' 'n'
0x07 'b' 'f'
0x08 'b' 'v'
0x09 'g' 'p'
0x0A 'n' 'p'
0x0B 'b' 'p'
Note: If Suffix2 = 'f', the name of FRM file used Suffix3

Table 2.5-Match values ID1 and Suffix3

ID2 Suffix3
0x00 '0 '
0x01 '1 '
0x02 '2 '

Prototype identifier (PID)Edit

Prototype ID (PID) is a type of the following:

            |                                            | 
            |                                            ---------------------------------------- The index of LST-file
            ------------------------------------------------------------------------------------- Type of object (ObjType)

At meaning 'type of object' is overlapped the following limitations:

0x00 ≤ ObjType ≤ 0x0B 

but PRO- files exist only for objects with

0x00 ≤ ObjType ≤ 0x05 

(0x00: items (objects), 0x01: critters (substance) 0x02: scenery (landscape), 0x03: walls (walls), 0x04: tiles (floor tiles), 0x05: misc (miscellaneous)).

On the index file in LST- no restrictions.

However, due to the characteristics of initializing the internal structures Mapper can create PID only with the index starting with the unit. Therefore, the zero indesom PID does not exist.


The index of new PID LST- file generated from the billing Mapper- BIS is a number of existing PRO- files of this type of facility. Mapper does not verify the existence PRO- file for a new PID, and therefore possible that a show has been created PID sschestvuyuschego prototype.

Script identifier (SID)Edit

Script ID (SID) is a type of the following:

            |                                            |
            |                                            ---------------------------------------- The index of LST- file
            ------------------------------------------------------------------------------------- Type of script (ScriptType)

At meaning 'Type script' is overlapped the following limitations:

0x00 ≤ ScriptType ≤ 0x04 

On the index file in LST- no restrictions.

Type scripts shown in table 3.1

Table 3.1-Type scripts

Type of script



(Information from SeaWolf)


(Information from Mapper2.exe)

0x00 - s_system
0x01 spatial s_spatial
0x02 items s_time
0x03 scenery s_item
0x04 critters s_critter

It should also be noted that the authors have not met cards (MAP- files), which used scripts types 0x00 and 0x02.

Sound Code IDEdit

Id sound effects (Sound Code ID) is a character in the filename sound effects. The location of the symbol in the name of the file varies depending on the type of object. Could a value of'0 '-'9', 'A', 'Z','!','@','#','$','_'.


Animation letter codes have been added; they are not in the original file.
