- Extentions: vb
In 1996, Beam Software developed a game called [http://www.mobygames.com/game/dos/norse-by-norse-west-the-return-of-the-lost-vikings The Lost Vikings II (a.k.a. Norse By Norse West: The Return of the Lost Vikings)]. The PC version of this game uses a multimedia format with the file signature 'SIFF'. The format can transport audio and video (which are .vb files) or just audio (which are .son files).
The general fourcc chunk format is as follows:
bytes 0-3 chunk type bytes 4-7 chunk size (not including 8-byte chunk preamble) bytes 8.. chunk payload
It is important to note that in the fourcc chunk preamble, the size field is big-endian. However, all other multi-byte numbers in the file are little-endian.
A VB file begins with a 'SIFF' file signature, followed by the total length of the file, minus 8 bytes. Bytes 8-11 contain the version fourcc, e.g. 'VBV1'. Then comes the header, which is laid out as follows:
bytes 0-3 header fourcc ('VBHD') bytes 4-7 header length (should be 32 == 0x20) bytes 8-9 unknown, but might be header version bytes 10-11 video width bytes 12-13 video height
