BFLAN (File Format)
BFLAN is an updated format for BRLAN files on the Wii.
File Header (FLAN)
| Offset | Size | Description |
|---|---|---|
| 0x00 | 4 | Magic (File Layout ANimation) |
| 0x04 | 2 | Byte Order Mark |
| 0x06 | 2 | Header size (always 0x14) |
| 0x08 | 4 | Flags (But what?) |
| 0x0C | 4 | Size of entire file |
| 0x10 | 4 | Unknown (Always 0x00020000 ???) |
pat1 Section (???)
Notes
BFLAN files have a tree-like structure, FLAN encompasses the whole file, pat1 looks like a header for pai1, pai1 holds all entry data.
Header
| Offset | Size | Description |
|---|---|---|
| 0x00 | 4 | Magic ("pat1") |
| 0x04 | 4 | Section size (all sub-data) |
| 0x08 | 4 | Unknown, seems to always be 1, probably number of entries |
| 0x0C | 4 | Offset to first file string (Dunno what used for, always 0x1C?) |
| 0x10 | 4 | Offset to second file string (Dunno what used for) |
| 0x14 | 4 | Unknown, seems to be number of string entries minus 1 (0x14A -> 0x149) |
| 0x18 | 4 | Padding ??? |
After is two strings, each padded to 4 bytes. After that is a bunch of zeroes (section padded to 8 or 16 bytes? Reference files have 0x44, 0x48, and 0x50 as size.
Texture Pattern (FLTP)
Header
| Offset | Size | Description |
|---|---|---|
| 0x00 | 4 | Magic (caFe Layout Texture Pattern) |
| 0x04 | 4 | Unknown (Always 0x01000000 ???) |
| 0x08 | 4 | Unknown, usually 0x0C, could be offset or header length |
| 0x0C | 4 | Unknown (Probably flags, usually 0x100) |
| 0x10 | 2 | Number of entries (padded to 4 bytes/shifted ????) |
| 0x14 | 4 | 0x0C again, probably another section size |
Entries
Each entry is 8 bytes, seems to a float, followed by flags (second byte looks like a sorting/matching number with strings).
