BFLIM (File Format)
The BFLIM file format (Binary caFe Layout IMage) is used to store layout images.
Header
The header is at the end of the file (to align the image data without the need for additional padding). It is always 0x14 bytes.
| Offset | Size | Type | Description |
|---|---|---|---|
| 0x00 | 4 | Char[4] | File magic. Always FLIM in ASCII. |
| 0x04 | 2 | UInt16 | Byte order mark (BOM): 0xFEFF for big endian and 0xFFFE for little endian. Not handled on consoles, so the file data must be stored in the endianness of the target console (e.g. big endian for the Wii U). |
| 0x06 | 2 | UInt16 | Header size, always 0x14. |
| 0x08 | 4 | UInt32 | Version of this file. |
| 0x0C | 4 | UInt32 | File size in bytes. |
| 0x10 | 2 | UInt16 | Number of data blocks, always 0x01. |
| 0x12 | 2 | UInt16 | Padding. Seems to reflect upper 2 bytes of filesize (apparently uninitialized memory garbage from file generator). |
| 0x14 | End of FLIM header | ||
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 | Type | Description |
|---|---|---|---|
| 0x14 | 4 | Char[4] | Section magic. Always imag in ASCII. |
| 0x18 | 4 | UInt32 | Parse information size (total block size), always 0x10 (this and next 0xC bytes). |
| 0x1C | 2 | UInt16 | Width. |
| 0x1E | 2 | UInt16 | Height. |
| 0x20 | 2 | UInt16 | File alignment, always a power of 2. Usually 0x800, 0x1000 or 0x2000. |
| 0x22 | 1 | Byte | Format, how the data is stored. |
| 0x23 | 1 | Byte | Tile mode and Swizzle, packed as bits SSSTTTTT.
|
| 0x24 | 4 | UInt32 | Raw data size, always 0xC minus 0x28 (the header). |
| 0x28 | End of Image header | ||
