==Index Table==
 +
There are 2 known formats of indexes in the game. The format version is found in the file header.
 +
 
 +
A third format has been discovered, structure currently unknown. The Index Minor Version is an actual zero, so this would be called "7.-1" by the logic used here. This format has been seen in files that ship with the game, and is believed to have been seen in files generated by the game, but has not yet been seen in user-created files [for obvious reasons ;) ]. These files were discovered by the simple expedient of having a file-scanning tool choke on them during a scan of the entire game.

Archive format used many Maxis developed games, including The Sims 2, SimCity 4 and Spore.

Contents

[edit] Format

Most Sims 2 Data is as you probably know stored in various types of archive files that all have the same internal format such as package, cache, etc. This format is proprietary to Maxis and has been used in the SimCity 4, and The Sims Online as well as this one.

Entries may be compressed with RefPack compression depending on their entry data.

For an examination of the Spore DBPF format, see Spore:DBPF

[edit] Overview

This is the general structure of DatabasePackedFile packages:

Header (96 bytes)

File 1
File 2
...
File n
Index Entry 1 (20 bytes)
Index Entry 2
...
Index Entry n 

Header first, individual files following with no filenames and a small file header area at the beginning of each followed by an index of all the files in the archive. Note that files may appear after the index table in files that are updated.

[edit] Index Table

There are 2 known formats of indexes in the game. The format version is found in the file header.

A third format has been discovered, structure currently unknown. The Index Minor Version is an actual zero, so this would be called "7.-1" by the logic used here. This format has been seen in files that ship with the game, and is believed to have been seen in files generated by the game, but has not yet been seen in user-created files [for obvious reasons ;) ]. These files were discovered by the simple expedient of having a file-scanning tool choke on them during a scan of the entire game.

In order that others may investigate, a list of the files with this previously-unknown index format:

[edit] DBPF 1.x

A Hole record contains the location and size of all holes in a DBPF file.

DWORD
Hole Location
DWORD
Hole size

Holes are created when the game deletes something from a DBPF. The holes themselves are simply junk data of the appropriate length to fill the hole.

[edit] File

Bulk of DBPF packages. Each file is either uncompressed or compressed. To check if a file is compressed you first need to read the DIR resource, if it exists. (See the corresponding entry for a description). If no DIR entry exists, then no files within the package are compressed.

[edit] Compression

When reading a DBPF file, the first thing you should do is check to see if any chunks inside are compressed. This is done via the DIR resource.

For example code and a description of the mechanics, see DBPF Compression.

[edit] Directory Files

These are used for compression lists. See E86B1EEF

[edit] Header

Only if the file is compressed

DWORD
Compressed Size of file
WORD
Compression ID (0x10FB) QFS Compression. (See packages for compression information)
3 bytes
Uncompressed Size of file

[edit] Body

Raw data of the files. See InternalFormats for a list.

[edit] Pseudocode

To read files inside a .package file you need to perform the following steps, in order

  • Read the DBPF header
  • Read the Index tables
  • Check for a DIR record
  • Check for the file you want to extract
  • Is this file compressed? If so, uncompress it
  • Read the file data and process accordingly

For an example PHP class for reading DBPF files, see DBPF/Source Code

[edit] Visual Format Guide

Having recently started poking around with the DBPF format again for the SimCity 4 community on SimTropolis, I created some visual guides to the DBPF archive format. Hopefully they will be found useful here.

DBPF v1.x Visual Guide
DBPF v1.x
DBPF v2.0 Visual Guide
DBPF v2.0

Some information was taken from old DatGen source code, such as the Created/Modified timestamps and possible Flags DWORD. That information may not be accurate, as it was some time ago that I last chatted with Maxoids about the DBPF format.
