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

Block structure

Each block of compressed data has the following structure:

Data type Name Description

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.
