CC1 Format is a container of compressed data blocks used by several games developed (not only published) by Infogrames Europe SA around ~1988-1992, used to store game executables, graphics, language texts and sounds. The files usually have a .CC1 extension, though some variations like .1 and .C1 also occur. One game, Hostage: Rescue Mission, uses a .PXI extension.

The files have no specific identifiable information header to detect if the file is a CC1 file. Usually, the only hint is the file extension.

There is a variation of the CC1 format without the ability to contain multiple compressed blocks but just one, sometimes using the extension CC0

CC1 and CC0 using the same compression algorithm

Header of CC1

Data type	Name	Description
UINT16LE	NrOfFiles	Amount of compressed blocks.
UINT32LE[NrOfFiles]	OffsetsTable	Offsets of the compressed blocks.

This header is followed by the blocks of compressed data. The blocks don't need to be in order and can contain gaps between

Header of CC0

Data type	Name	Description
UINT16LE	Unknown	Always value 0

This header is followed by a single block of compressed data.

Block structure

Each block of compressed data has the following structure:

Data type	Name	Description
UINT32LE	PackedSize	Packed data size.
UINT32LE	UnpackedSize	Unpacked data size.
UINT8[PackedSize]	PackedData	The packed data.

There is no information inside the archive to determine what each block of compressed data is; the blocks have no names or other identifiable values.
