BRBNK (Binary Revolution BaNK) is a sub file format found in BRSAR files from many Wii games. It consists of a table of instance parameters that link to the audio samples used in MIDI-like sequences (BRSEQ files).
File Format
File Header
| Offset | Type | Description |
|---|---|---|
| 0x00 | String | File magic. Always RBNK in ASCII. |
| 0x04 | UInt16 | Byte order mark (BOM): The value is always 0xFEFF. If value 0xFFFE is read, then the false endian is used. Mario Kart Wii uses nearly always big endian (bytes 0xFE,0xFF). |
| 0x06 | UInt16 | Version number of the file format. (?) |
| 0x08 | UInt32 | Length of the file in bytes. |
| 0x0C | UInt16 | Length of this header in bytes. |
| 0x0E | UInt16 | Number of sections. |
| 0x10 | UInt32 | Offset to DATA section. |
| 0x14 | UInt32 | Length of DATA section. |
| 0x18 | Byte[8] | Padding. |
| 0x20 | End of this file header | |
DATA
The DATA section starts with a header.
| Offset | Type | Description |
|---|---|---|
| 0x00 | String | Section magic. Always DATA in ASCII. |
| 0x04 | UInt32 | Length of this section. |
| 0x08 | End of this header | |
Bank Data Table
The DATA header is followed by a table that lists the entries of bank data. All offsets are relative to the start of this table.
| Offset | Type | Description |
|---|---|---|
| 0x00 | UInt32 | Number of Bank Data Entries. |
| 0x04 | Byte[4] | Unknown. Always 0x01010000. |
| 0x08 | UInt32 | Offset to the first Bank Data Entry. |
| 0x0C | Byte[4] | Unknown. Always 0x01010000. |
| 0x10 | UInt32 | Offset to the second Bank Data Entry. |
