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

All integers are Big Endian unless stated otherwise.

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

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.

Header
Type	Description
UInt16	Data Start Offset
UInt16	File Count

Same as BIGF/BIG4?
