Important Files

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.

The KERNEL.BIN file consists of the following sections.

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.
