Contents
The KERNEL.BIN Archive.
The file /INIT/KERNEL.BIN is in BIN-GZIP format. This format is explained later in this document. 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 FF Text files.

Section 3: Savemap
This is all the initial values and structure for most of the Savemap, excluding the header data and the tail of the last bank (0x0054 to 0x0FE7). This is copied into RAM on initialization. This format is explained in the "Menu" Section.
Section 4: Initialization data
This contains the starting stats for the characters and related game states. On "New Game", this data is copied directly into the save map (from offset 0x0054 to 0x0BAF) which is explained in the "Menu" section. This data has the same format as the data explained in that section.
Section 5: Item data format
This contains the item data. Each item record is 27 bytes long.
