VIV is an archive format found in Electronic Arts games; it has been observed in the NBA Live and Need For Speed game series, and is probably in other games, used to contain files such as graphics in FSH format. It appears the files are stored in an uncompressed manner. This format was used around 1998; later, in the 2000s, the BIG archive format was used.
VIV files start with bytes
