Information on BCSV files
All information is from Animal Crossing: New Horizons
Contents
General
BCSV files contain a list of content blocks. The header contains metadata for each content block
Header
| Offset | Size | Description |
|---|---|---|
| 0x00 | 0x4 | Number of content blocks |
| 0x04 | 0x4 | Content block size |
| 0x08 | 0x2 | Number of offsets |
| 0x0A | 0x2 | Always 0x0101 |
| 0x0C | 0x4 | VSCB Magic |
| 0x10 | 0xC | Unknown |
| 0x1C | 0x8*Number of offsets | Offset list |
Offsets
Offsets in the header are made up of two fields
| Offset | Size | Description |
|---|---|---|
| 0x00 | 0x4 | Data identifier |
| 0x04 | 0x4 | Offset relative to content block |
The data identifier determines what type of data the offset is pointing to. The meaning behind each identifier seems to rely on the context of the files content, generally, with only a small number of identifiers being reused in multiple files. In AC:NH there is a total 2048 unique identifiers, with only 191 being reused in multiple files. For a list of all identifiers in AC:NH and the files they are used in, see here https://pastebin.com/KnbnD1r8
Content Block
Content blocks always begin with their offset relative to the file start, and then contain the blocks data
| Offset | Size | Description |
|---|---|---|
| 0x00 | 0x4 | Offset relative to file start |
| 0x04 | Content block data |
