C2S

A C2S file (having the extension .c2s) is the file format where Chip's Challenge 2 stores a levelset's top-level save data.

The file is a binary file consisting of several sections one after the other, terminated by the END section. Each section begins with a section header, which is followed by the section's data. Unlike the C2H file, there is only one save block, which represents the current save state of the levelset.

All data in the file is little-endian.

Format

Section header

Bytes	Content
4	Four character code identifying the section, see table below. Codes shorter than 4 characters (such as "END") are padded with spaces (making "END " in this case).
4	The length of the section's data

Section types

Section ID	Content Type	Content
CC2S	Null-terminated string	The file's version. The latest version is "7".
FILE	Null-terminated string	The levelset's file name (*.c2g)
PATH	Null-terminated string	The full path to the game data directory (i.e. the directory containing the .c2g file listed in the FILE block)
GAME	100 bytes	Save data. The format is identical to the format of the SAVE section in C2H files. This block describes the last level played, and the total score for the levelset.
END	No content (length is 0)	Signifies end of file
