====== BIGF ======

This is an archive format used to organize game assets. It has the file extension //.big//.

===== Header =====

The header takes up the first 0x10 bytes of the archive.

^Offset^#Bytes^Description^
|0x00|4|"BIGF"|
|0x04|4|Size of the archive|
|0x08|4|Number of files|
|0x0C|4|Size of the index table|

Following the header is the index table.

===== Index table entry =====

Each file in the archive has an entry in the index table.

^Offset^#Bytes^Description^
|0x00|4|offset in archive|
|0x04|4|Size of the file|
|0x08|Varies|Filename|

  * The filename is an ascii string that has a null terminator, and there seems to be no hard limit on the length.
  * If the first two bytes of the file start with 0x10FB, then that data is compressed with the [[supercross_2000:eahd|EAHD format]].

===== Trivia =====
  * The main BIGF archive within Supercross 2000 takes up 91% of the N64 ROM at about 14.56 MB
