== ISO.BIN.EDAT ==
==iso.bin structure (decrypted)==
 
ISO.BIN.EDAT is an encryted container format. First step to work with it is to decrypt it <!--more info an internal links to other wiki pages needed-->
 
After decryption, we should refer to ISO.BIN.EDAT as ISO.BIN.DAT (without the "E"... so the EDAT became a DAT).
 
==ISO.BIN.DAT (decrypted)==
This can be considered an intermediate container composed by the ISO.BIN + a 40 bytes signature at bottom<br>
For the purpose of this wiki page and the concept of extracting data  from layers like an onion we need to delete the last 40 bytes to convert a ISO.BIN.DAT into a ISO.BIN<br>
The signature is intended as a sanity check to the ISO.BIN data. In other words if you are going to modify the ISO.BIN you will need to generate a new signature for it when rebuilding it<br>
Example source-code to generate the 40 byte signature can be found in sign3.py which is part of [https://github.com/sahlberg/pop-fe pop-fe].

All offsets are in little endian (except in the last table where there are two counters in decimal)

Always exists in PS1 classic multidiscs (the example below is from ff8), in the official PS1 classics single disc doesnt exists, but the custom PS1 classics single discs can use it (there are custom tools that adds it in all cases)

The audio tracks themselves are raw ATRAC3 streams without a header.
One way to create such blobs is to use the atracdenc encoder and strip of the first 0x60 bytes which is the header. The resulting blob is what the Audio tracks table entries will point to.

====Subchannel data====
There are 2 "special" entries to mark the "start of a disc" (FFFFFFFF 00000000 FFFFFFFF), and the "end of a disc" (FFFFFFFF FFFFFFFF FFFFFFFF). Between the start and the end, there are a variable number of entries.
This is data stored in separate .pgd in psar (0xED4 [0x12D4] in ISO header point to it if available), should be required only for games that use libcrypt protection (LC2 and higher).
Header of decrypted file is FFFFFFFF 00000000 FFFFFFFF, end of file is marked by FFFFFFFF FFFFFFFF FFFFFFFF.
Values are always 150 sectors lower than real disc sector (pregap?). Values are in little endian (sector only actually, others are 1 byte values). See section below for example code on how to generate this table.


{| class="wikitable"
There is also an added string at the end of the last disc (after the last FFFFFFFF FFFFFFFF FFFFFFFF entry)... is a 40 bytes unknown area (in my example my game had 4 discs so maybe this area is divided in chunks of 10 bytes for each disc)
|-

So as an example... for a game with 4 discs this table is:

* next entries of disc 1 --> data from disc.... the number is variable

There are some new formats present in PS2 Classics. The first one is ISO.BIN.ENC, the second one is .dxt, which is inside CONTENT folder and there's also a single file named CONFIG. You can see more about this when you first install a PS2 Classic. There's also a  problem with the Data while trying to execute the instalable file. The message Unsupported Data appears on the screen when highliting the file and the error 80028F14 is shown while trying to start.<br>

This was made with the Max Payne game. There could probably be other formats present aswell
