One of EA's archive formats, commonly used (in various forms) in the SSX games.

Tools

File Data

All integers are Big Endian unless stated otherwise.

Magic words
Hex	ASCII
C0FB	Àû
42494734	BIG4
42494746	BIGF

Official packing tools identify C0FB as "old 24bit" and BIGF as "old 32bit" respectively.

BIGF/BIG4

Header
Type	Description
UInt32 LE	Big File Size
UInt32	File Count
UInt32	Data Start Offset

File Entries
Type	Description
UInt32	Offset
UInt32	File Size
C String	Path

If the first word of the file data starts with 0x10FB, the file is RefPack compressed.

Debug Info Footer
Type	Description
char[4]	Lumpy version/creator code (e.g: `L218`)
uint32	Lumpy flags (as a bitflag. Unknown)

This footer contains a tiny bit of debug info about the version of Lumpy (and flags used) used to pack the archive.

C0FB

Header
Type	Description
UInt16	Data Start Offset
UInt16	File Count

File Entries
Type	Description
UInt24	Offset
UInt24	File Size
C String	Path

Footer

Same as BIGF/BIG4?
