Format
A KiSS set consists of many files of a number of different formats. These are packaged for distribution as a single set or 'doll' in LZH format (a preferred archive format in Japan) which viewer programs can read as a whole to obtain the individual files.
Most files are 'cel' files which are raw, uncompressed graphics data analogous to animation cells. KiSS/GS2 specification cels also require a KCF (KiSS Colour File) as a palette, but CKiSS specification cels do not. A KCF also can control background colour and contain multiple palettes that can be swapped for lighting and colour change effects. All KiSS binary files (KCF, standard and CKiSS cels) since KiSS/GS2 share a common 32 byte binary header record identifying the size, type and format of KiSS data they contain.
A configuration file is also required to control field size, layering, cel position, use of palettes, and interaction and animation events.
In addition Midi files for music and WAV files for sound clips may be used, and generally some form of text documentation is included by the artist.
