By myst6re = 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:
{| borderclass="1" cellspacing="1" cellpadding="3" align="center" style="border: 1px solid black; border-collapse: collapse;wikitable"! style="background:rgb(204,204,204)" | Offset! style="background:rgb(204,204,204)" | Size! style="background:rgb(204,204,204)" | Data
|-
| 0
| 4
| Location of file in sectors (relative to the start of the '''iso''')
|-
| 4
| 4
| Size of filein 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'''! {| class="wikitable"!

== Field Files == In the list of root files, the third file is in fact the "FIELD.BIN". This file are is [[FF7/LZS_format|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.[[FF8/FileFormat_MCH|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.MAP 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:.<ul><li>EXAMPLE=== First file (*.MIM ) === {| class= HEADER + example.pvp + "wikitable"!

Note The main difference is that the file is not quite LZS, the header is largermodels data are compressed.</ul>
