[edit] DBPF Packages
Sims 3 stores multiple resource types in an archive format known by it's magic number of "DBPF". On disk, these archives have one of a number of extensions:
| *.package | General collection of resources |
| *.world | Resources comprising a "world" |
| *.dbc | Collection of DBPF archives in a single archive |
[edit] Package Header
96 bytes: "standard" DBPF 2.0 format; DBBF not seen; DBPP is encrypted.
DWORD magic ;; "DBPF" DWORD major ;; 2 DWORD minor ;; 0 BYTE[24] unknown1 DWORD ;; number of index entries - if zero, size and position also zero BYTE[4] unknown2 DWORD ;; size of index on disk in bytes BYTE[12] unknown3 DWORD index_version ;; always 3 DWORD ;; position of index (absolute) BYTE[28] unknown4
[edit] The Index
If position is not zero, at that position:
DWORD ;; Index Type, see subsection below <Index Header> <Index Entry>[number of index entries]
Note: The [number of index entries] value in the Package Header excludes the Index Header.
Each Index Entry (and the Index Header) contains a variable number of DWORD fields in the following order:
| Bitfield | Field | |
|---|---|---|
| 0 | ResourceType | |
| 1 | ResourceGroup | Top byte is a set of flags |
| 2 | InstanceHi | |
| 3 | InstanceLo | |
| 4 | Chunkoffset | Absolute location in package |
| 5 | Filesize (lo 31bits), Unknown1 (hi bit) | Length of data in package |
| 6 | Memsize | Length of uncompressed data |
| 7 | Compressed (lo WORD), Unknown2 (hi WORD) | Compressed is 0x0000 or 0xFFFF |
[edit] Index Type
This is a bitfield that determines which DWORD fields exist in the Index Header and the Index Entries.
[edit] Index Header
The header provides the data that is constant to all entries, essentially a kind of compression. However not all data is valid to be included in the index header for all entries.
DWORD[(for each SET bit in Index Type)]
[edit] Index Entry
DWORD[(for each UNSET bits in Index Type)]
Note: Because of the different treatment of the bitfield, fields that exist in the Index Header will NOT exist in all Index Entries, and vice versa.
[edit] Chunk Compression
