Death Stranding (PS4)

[vladgohn]

Hi, daemon!
I’ve been trying for days to solve the problem of exporting models from Death Stranding. but i'm a newbie.

• Tell me please, for a successful implementation, I need a fake PKG?
• Is there somewhere in the clouds (possibly yours) a given package suitable for decryption?
• I found CUSA of the original version of DS, will this help me solve the problem?
• Also I have both, PS4 + acquired digital copy of the game

I ask for help, as soon as I can successfully complete this, I will make a video on YouTube to help others

no

no

no

good, but this will not help you

Death Stranding is now released on steam. Will there be PC support in the future?

PS4 tool can just work with PC. Files must be almost the same.

Nah, it does not works (for me). There are 3 problems.

1)

Code: Select all

File not found in cache! prefetch/fullgame.prefetch.core

Resolved by copying tool in game directory.

2)

Code: Select all

Необработанное исключение: System.IO.EndOfStreamException: Чтение после конца потока невозможно.
   в System.IO.MemoryStream.InternalReadInt32()
   в ?????????????????????????????????????????.?????????????????????????????????????????(String[] )

3)

Code: Select all

Необработанное исключение: OutOfMemoryException.

Problem 2 and 3 - due to the fact tool protected by some obfuscator (Win10 Pro Lic detect it as Trojan:Win32/Occamy.C > Confuser ??), it is impossible to understand what the error is and why it occurs, because obfuscator protecting all classes, consts, strings and methods names cause it's a .Net project. I just was planning to add decryption code for Naomi's project for supporting encrypted files and wanted to compare some data files, but, apparently, not destiny

I suppose that the master key (init hash) is different from the PC version, not sure because I do not know it from PS4 (if PS4 also encrypted as PC of cource).

Can you tell me what is the identifier for bin files in PS4 version? 0x20304050 or 0x21304050?

It's a different format, the previously mapped out structures will not work.
PC Magic is 0x21304050, PS4 is likely 0x20304050, but it could also be that Death Stranding is using a newer iteration of the engine in general as opposed to the file format being a console-difference.

[Espio]

Maybe start work with a movies container? It must have BINK files inside and the structure at the beginning and the end of the file seems just xored.

This seems very nice but do you plan to make it work for the PC version? It appears to crash on startup.

There is only one difference - an identifier that specifies that the archives are encrypted.

1) Header encrypted
2) Record table encrypted
3) Block table encrypted
4) Files data aslo encrypted
5) Structures have not changed

I have solved the problem with the decrypting of the header and tables. now i ve trying to decrypt content because algorithm is little bit different.

Movies archive also encrypted

0x20304050 according to the files I have, PS4 version is also not encrypted.

Ah, you here This is an interesting project

I'll give information on encryption later.

Here is my test tool for decrypting and dump the header and tables (source's included).
Not a professional code, but I think it's okay

PS: There is no code to decrypt files yet.

Great job! Do you looked code for decrypt files data? Seems MD5 is involved in decryption and there other key (salt) are used

Code: Select all

static unsigned long lpSalt2[4] = {
       0x6C084A37, 0x7E159D95, 0x3D5AF7E8, 0x18AA7D3F};

or

Code: Select all

static unsigned char lpSalt2[16] = {
       0x37, 0x4A, 0x08, 0x6C, 0x95, 0x9D, 0x15, 0x7E,
       0xE8, 0xF7, 0x5A, 0x3D, 0x3F, 0x7D, 0xAA, 0x18};

As you wish

Mind slapping a license on that project? I'm planning on rewriting ProjectZeroDawn to C++ when the PC port releases and I'd love to have a C++ point of reference.
