The BFLIM file format (Binary caFe Layout IMage) is used to store layout images.
Header
The header is, because of hardware restrictions, at the end of the file. It is always 0x14 bytes.
Offset | Size | Description |
---|---|---|
0x00 | 4 | "FLIM" File Identifier, ASCII string. |
0x04 | 2 | Byte order mark (BOM): 0xFE,0xFF for big endian and 0xFF,0xFE for little endian. |
0x06 | 2 | Header size, always 0x14. |
0x08 | 4 | Version of this file. |
0x0C | 4 | Filesize |
0x10 | 2 | Unknown, always 0x01. |
0x12 | 1 | Multiplier?, always upper 2 bytes of filesize. |
0x13 | 1 | Unknown, always 0. |
Image Information
Comes directly after header, always 0x14 bytes. The formats are not the same in games like New Super Mario Bros U, be sure to use filename if possible (EG: ^l).
Offset | Size | Description |
---|---|---|
0x14 | 4 | "imag", some signature, ASCII string. |
0x18 | 4 | Parse information size, always 0x10 (this and next 0xC bytes). |
0x1C | 2 | Width |
0x1E | 2 | Height |
0x20 | 2 | Alignment usually 0x800 (2048) or 0x1000 (4096) |
0x22 | 1 | Format, how the data is stored. |
0x23 | 1 | Swizzle, first nibble is swizzle times two (2 is 1, 4 is 2, etc), second seems to always 4 |
0x24 | 4 | Raw data size, always 0xC minus 0x28 (the header). |
