'''NCCS ''' (extension being .ncss) is the file format used for storing [[NotCC]] level scores and solutions, similar to the [[TWS]] file format.

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.

All data in the file is little-endian.

== Format ==
=== Section header ===
{| class="wikitable" border="1"
!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 ===
{| class="wikitable" border="1"
!Section ID
!Content Type
!Content
|-
|NCCS
|Null-terminated string
|The file's version. The latest version is "02".
|-
|FILE
|Null-terminated string
|The level's (or level set's) file name
|-
|TYPE
|Null-terminated string
|Usually the name of the levelset. For the base CC2 set it's "Chips Challenge 2". If the level does not have a proper set name (eg. [[DAT]]s, [[C2M]]s outside of sets), excluded.
|-
|NAME
|Null-terminated string
|The level's title, excluded if the level has no title.
|-
|MISC
|100 bytes
|Level miscellaneous data. The format is identical to the format of the [[C2H#Save_section|SAVE section]] in [[C2H]] files.
|-
|SLTN/PSLN
|Level solution
|The recorded level solution, identical to the [[C2M#REPL_.2F_PRPL_section|REPL section]] of the C2M file, excluding the first three bytes. The PSLN section is compressed, the SLTN section is not.
|-
|STAT
|See STAT section below
|The state for some level variables
|-
|END
|No content (length is 0)
|Signifies end of file
|}

==== Section packing ====

"PSLN" sections are packed via the same [[C2M#Section_packing|packing algorithm]] as C2M.

=== STAT section ===

The STAT section contains variables which are most likely to cause a change on the level outcome, contrary to some data in the MISC section, which can only be vital in obscure scenarios.

This section is made up of many sub-sections, each for a single variable, for extensibility.

A single subsection looks like this:

{| class="wikitable" border="1"
!Bytes
!Content
|-
|1
|The ID of the section
|-
|1
|Length of the section, in bytes. (Multiple sub-sections should be used for larger data)
|-
|Varies
|The sub-section data itself
|}

Here is a list of existing sub-section types:

{| class="wikitable" border="1"
!ID
!Length
!Data description
|-
|0x01
|1
|[[Random force floor]] initial direction
|-
|0x02
|1
|[[Blob]] randomness seed
|}
