The KERNEL.BIN Archive
The file KERNEL.BIN archive is in 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 FF Text files.

The KERNEL2.BIN Archive
On the PC version there exists a secondary kernel archive called KERNEL2.BIN. 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. See the section on BIN types and LZS compression later in this document for more information.
