FF8DISCX.IMG File Format

Almost all of the game files are hidden in the FF8DISCX.IMG (with X=disc number) file.

Root Files

In the case of a Japanese iso, the file begins directly with a list of file location and size, with the following format:

Offset Size Data
0 4 Location of file in sectors (relative to the start of the iso)
4 4 Size of file in bytes

In the case of a PAL iso, there are 5 unknown sectors (a sector = 2048 bytes in data, 2352 bytes in disk) before this list of files.

Notes:

  • I do not have the American iso, please fix this article if you can.
  • We do not know how many files there are in the list, neither file names!
  • Each file in FF8DISCX.IMG are relative to the start of the iso!

Field Files

In the list of root files, the third file is in fact the "FIELD.BIN". This file is LZS compressed, and contains some informations, like the list of field files position and size.

Find the file list is approximate, I am trying to find some bytes: "\x04\x00\x05\x24\x18\x00\xbf\x8f\x14\x00\xb1\x8f\x10\x00\xb0\x8f\x20\x00\xbd\x27\x08\x00\xe0\x03\x00\x00\x00\x00" (size=28), normally, there is the list right after this sequence of bytes, and before the "\x00\x00\x01\x00\x02\x00\x03\x00" (size=8) sequence.

Order of files (sorted by id):

  • D000.MCH -> D075.MCH files [id=0 -> id=76]
  • Field files (MIM, DAT and LZK) [id=77 -> id=last]

There are three LZSed files for each field: EXAMPLE.MIM, EXAMPLE.DAT and EXAMPLE.LZK (Extension names *.MIM, *.DAT and *.LZK found in PC version, field.fs > mapdata.fs > map1.bak). If you want to convert Playstation fields to PC fields format, this is a concatenation of some PC files.
