Editing ISO.BIN.EDAT

== ISO.BIN.EDAT ==

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].

==ISO.BIN structure==
All offsets are in little endian (except in the last table where there are two counters in decimal)

 1 block = 1024 bytes (0x400)
 1 cluster = 16 blocks = 1024*16 bytes =16384 bytes (0x4000)

 disc_starts ----------> 0x000400 (disc1), 0x100400 (disc2), 0x200400 (disc3), 0x300400 (disc4), etc...
 disc_tocs -----------> 0x000C00 (disc1), 0x100C00 (disc2), 0x200C00 (disc3), 0x300C00 (disc4), etc...
 disc_map_tables ----> 0x004400 (disc1), 0x104400 (disc2), 0x204400 (disc3), 0x304400 (disc4), etc...

===Header (optional)===
 1 block = 1024 bytes (0x400)

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)

====Audio tracks table====
Entry structure:

|-

|}
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.

====Disc map table====
The table has an area reserved of 1032192 bytes. Divided in 32256 entries, of 32 bytes each entry. The number of used entryes in the file_table can vary (seems to be dependant of the .iso contents). The number of entries availables to store data is affected by a checksum (16 bytes) that is present only in the the last block of each cluster (in block nº16 of every cluster)
When this checksum is between used entryes... his length is 32 bytes (it "steals" the area of one entry)
Seems to be a checksum of this block... when the block is filled with zeroes the checksum is : 1CCE0033 60C6E8A6 B36A972D 00EAFDBF

The first 4 bytes of each entry (file offset from start of .iso root) increases for each entry in a amount of bytes determined by the previous entryes.... in other words... the second file in the .iso is displaced the number of bytes used by the first file... and the third file is displaced in a amount of bytes used by the addition of the sizes of first and second file

|-

|-
| rowspan="5" style="background-color:#DDDDDD;" | 1 || 0x00 || 0x04 (4 bytes) || '''file_offset''' || 0 || file offset from start of .iso root (for the first entry is always 0)

|-

|-
| style="background-color:#DDDDDD;" | Up to ? || || || || || same structure than the previous entry
|}

====Subchannel data====
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.

* You can decrypt any eboot.pbp from a mini OR pspremaster OR psn paid eboot(?) with npdpc
* You can use any header on an iso.bin, and the ps3 won't even try to check it
* (be) means that the generated table values will have to be endian swapped when using npdpc (now possible thanks to arnold)

==About PS2 Classics==
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

===ISO.BIN.EDAT===
For PSN PS2-Classics Games ISO.BIN.EDAT only contains the Title Id of the disc. Example:
<pre>SLES-12345</pre>
