SAVE.DAT files are archived data files that contain data for savegames. Everything about the player, party members, global variables, and state of the world map is stored here. The only thing not included is information about each town, which is stored in individual .SAV files. While they have the .DAT extension, they do not have the same format as other .DAT files. These files are found in \data\SAVEGAME\SlotXX, XX representing the number of the save game.
As with various other Fallout data files, if you're viewing this in a Hex editor, make sure it's in "Big Endian" (non-PC) display format.
Introduction[]
Almost everything has been verified for the Mac version of Fallout 2; there may be some differences between this and the Windows version.
A little explanation of the data types:
- ASCII (C-style) strings end with a 0 byte - the hex value
0x0, not the character '0'. So, if the length of an ASCII string is 32, it can contain 31 characters with0x0at the end.
- ASCII (C-style) strings end with a 0 byte - the hex value
- Most numbers are written as four byte integers, in big-endian (most significant byte first) format. Negative numbers are stored in two's complement format (e.g. -1 is
0xFFFFFFFF).
- Most numbers are written as four byte integers, in big-endian (most significant byte first) format. Negative numbers are stored in two's complement format (e.g. -1 is
- The data in a save.dat file is not written all at once, but in a series of separate functions. This can be seen when examining debug files (debug.log). When saving it has the following entries:
LOADSAVE: Save file header size written: XXXX bytes. LOADSAVE: Save function #X data size written: XXXX bytes. ...
where X is some number
This is done because different functions save different types of data (about quests, items, etc.). All the data is recorded sequentially. Therefore, to describe the file we divide the data into separate functions. There are 27 functions (not including the header). The numbering starts with zero.
Because parts of the data have variable sizes, it can be fairly difficult to find a particular part of the data. It is considerably easier with the help of the file description and looking in debug.log for the size of the right function.
Note: offsets for each function (beginning with the fourth) are shown relative to the end of the previous one.
Structure[]
Header[]
Size: 0x7563 (decimal 30051) bytes.
| Offset | Size (bytes) | Description |
|---|---|---|
| 0x00 | 0x18 | Value: 'FALLOUT SAVE FILE '
Description: SAVE.DAT file signature |
| 0x18 | 0x04 | Version of the game which made the save file. For example, for version 1.02 it is 00 01 00 02. |
| 0x1C | 0x01 | The letter 'R'. Ask the developers why. Could be 'R' for Release? |
| 0x1D | 0x20 | Player name. ASCII string, so the longest possible name is 31 characters. |
| 0x3D | 0x1E | Savegame name. ASCII string. |
| 0x5B | 0x02 | The day the game was saved. Realtime, not gametime. |
| 0x5D | 0x02 | The month. |
| 0x5F | 0x02 | The year. |
| 0x61 | 0x04 | Minutes + hours (24-hour format), realtime. E.g. if the time is 16:45, then it is 0x0000003D. (This is a bit odd, as 17:44 also gives 0x3D . Perhaps it was supposed to be two 2-byte numbers (0x0010, 0x002D for 16:45). It doesn't seem to be used in the game in any case.) |
| 0x65 | 0x02 | The in-game month; for example, June is 0x0006 . Used only for displaying on the load/save screen. |
| 0x67 | 0x02 | The in-game day, also used only for the load/save screen. |
| 0x69 | 0x02 | The in-game year, also used only for the load/save screen. |
| 0x6B | 0x04 | The in-game date. This field stores the time – the number of seconds since December 5th 2161 00:00:00 multiplied by 10 (the number of 'ticks'). [Fallout 1 starts at December 5th 2161] |
| 0x6F | 0x04 | Number of the map you are currently on (from maps.txt). First two bytes are map level, last two are map number. |
| 0x73 | 0x10 | Filename of the map you are currently on. I.e. if you are in the Arroyo temple, it is ARTEMPLE.sav. An ASCII string. |
| 0x83 | 0x7460 | This is a bitmap (bmp) image, with no header or palette. The palette is taken from master.dat or patch000.dat. Image size is 224x133. |
| 0x74E3 | 0x80 | This section is always filled with zeroes. |
Function 0 - Unused[]
Size: 0x00 (decimal 0) bytes. This function never writes anything.
Function 1 - Unknown[]
Size: 0x04 (decimal 4) bytes.
| Offset | Size (bytes) | Description |
|---|---|---|
| 0x7563 | 0x04 | Unknown |
Function 2 - GVARS[]
Size: variable. In Fallout 2 v1.02d it is 0x0AE0 (decimal 2784) bytes.
| Offset | Size (bytes) | Description |
|---|---|---|
| 0x7567 | 0x04 * NG | An array of global variables (GVAR). NG is the number of GVARs in vault13.gam . |
Function 3 - Maps[]
Size: variable.
| Offset | Size (bytes) | Description |
|---|---|---|
| 0x8047 | 0x04 | The number of open maps. Also the number of *.sav files in the save folder. |
| 0x804B | variable | The size of the next field varies depending on the number of opened maps. It is a list of file names of maps which have already been visited when the game is saved. These are ASCII strings, each ending with a 0x00 byte. |
| after map list | 0x04 | The size of AUTOMAP.DB - the temporary file game creates while playing in the data\maps and removes after. |
Function 4 - GVARS[]
Size: variable. In Fallout 2 v1.02d it is 0x0AE0 (decimal 2784) bytes.
This is an exact duplicate of Function #2. It's not known why this was done.
| Offset | Size (bytes) | Description |
|---|---|---|
| 0x00 | 0x04 * NG | An array of global variables (GVAR). NG is the number of GVARs in vault13.gam . |
Function 5 - Player and inventory[]

| 0x20 | 0x04 | Player FID number (appearance). Changes depending on what armor is worn. [0100000B] is the jumpsuit. Note that the engine will always change this value back to what you are wearing, so it's pointless to edit it here. |
| 0x24 | 0x04 | Unknown, usually 0x60002420. The last byte has some interesting properties. Setting the 0x10 bit puts the player in a permanent, always-successful sneak mode. Setting the 0x08 bit will draw the player under other critters and scenery. Setting the last byte to 00 will turn off the player light source. |
| 0x28 | 0x04 | Which level of the map the player is on. |
| 0x2C | 0x04 | Unknown |
| 0x30 | 0x18 | Unknown - Light distance and intensity? Some of it have to to with lighting up the player. |
