<center>[[Image:Gears_img_5.png]]</center> == The KERNEL.BIN Archive == The file KERNEL.BIN archive is in [[FF7/BIN-GZIP|BIN-GZIP format]]. It consists of 27 gziped sections concatenated together with a 6 byte header for each. This file is the same both on the PC and PSX versions. This holds all the static data and menu text for the game, with a look up table at the beginning of the section. Sections 10-27 are [[FF7/FF Text|FF Text files]]. The KERNEL.BIN file consists of the following sections. {| border="0" cellspacing="1" cellpadding="3" style="backgroundborder: rgb(0,0,0)" align="center"! style="background1px solid black; border-collapse:rgb(204,204,204)" align="center" | File! style="collapse; background:rgb(204,2040,204)" | Data! style="background:rgb(204,204,204)" | Offset|-|style="background:rgb(255,255,2550)" alignborder="center" | 1|style="background:rgb(255,255,255)" | [[FF7/Command data|Command data]]|stylecellspacing="background:rgb(255,255,255)1" | 0x0006|-|stylecellpadding="background:rgb(255,255,255)3" align="center" | 2|style="background:rgb(255,255,255)" | [[FF7/Attack data|Attack data]]|style="background:rgb(255,255,255)" | 0x0086|-|style="background:rgb(255,255,255)" ! align="center" | 3PSX Version|style="background:rgb(255,255,255)" | [[FF7/Savemap|Savemap]]|style="background:rgb(255,255,255)" | 0x063A|-|style="background:rgb(255,255,255)" ! align="center" | 4|style="background:rgb(255,255,255)" | [[FF7/Character starting stats|Character starting stats]]|style="background:rgb(255,255,255)" | 0x0F7F|-|style="background:rgb(255,255,255)" align="center" | 5|style="background:rgb(255,255,255)" | [[FF7/Item data|Item data]]|style="background:rgb(255,255,255)" | 0x111BPC Version

  == KERNEL.BIN Section formats == The first 9 sections of data (i.e. The non-text related items) have a typical BIN file format. The text sections (10-27) do not have the typical 6 byte header. The text sections have a header of pointers to the text block. The text is in FF text format.       === Section 4: Initialization data {| class=== This contains the starting stats for the characters and related game states. On "New Game", this data is copied directly into the [[FF&/Savemap|Savemap]] (from offset 0x0054 to 0x0BAF) which is explained in the "Menuwikitable" section. This data has the same format as the data explained in that section.! File! Data! Offset|-      === Section 9: Materia data format === This contains the Materia data. Each record is 20 bytes long.  {| border="0" cellpadding="3" cellspacing="1" style="background: rgb(0,0,0)" align="center"| 1! style="background:rgb(204,204,204); width=50px;" align="center" | Offset! style="background:rgb(204,204,204); width=50px;" [[FF7/Command_data| LengthCommand data]]! style="background:rgb(204,204,204); width:350px;" colspan="2" | Description0x0006

== The On the PC version there exists a secondary kernel archive called KERNEL2.BIN Archive ==. This archive contains only sections 10-27 (Text data) of KERNEL.BIN. The data was ungzipped from the original archive, concatenated together, and then LZSed into a single archive with a 4 byte header giving the length of the file.

On The maximum allotted storage space on the PC version there exists a secondary kernel archive called KERNEL2.BINfor all un-LZSed data in the kernel2. This archive contains only sections 10-27 bin is 27KB (Text data27648 bytes) of KERNEL.BIN. The data was ungzipped from This means that the original archive, concatenated together, and then LZSed into a single archive with a 4 byte header giving the length total size of the file. See the section on BIN types extracted files (text and LZS compression later in pointers) must be less than this document for more information.
