PS4 extracted files - assets unknown compression

[darkdamp]

Hi,

I've extracted a few PKG's from game dumps on PS4. Most assets are .psarc or similar but Order 1886 seems to be sticking out.
It has an COMPRESS header. I've checked against known compression as well as your signsrch but there's nothing to be found.

I've gathered the following, even though it's not much.

0x0: 43 4F 4D 50 52 45 53 53 18 61 //magic
0x10: // size
0x28: B7 // start of data

I'm attaching 3 files ranging from 1kb to 8kb. I'm able to provide more if needed and these files are all from 1kb to 1.5gb.

Thanks in advance

From what i can see.
0x0, 0x8 length, magic
0x8, 0x8 length, length of decompressed data(?)
0x10, 0x8 length, size of .dat file
0x18, 0x8 length, unknown
0x20, 0x8 length, size of compressed data
0x28 compressed data

unsure on the compression algorithm currently

Where did you get this and how?

Will see later.

I was going to ask help with The Order a few days ago, I uploaded samples but in the end I did not post.

So, if it is needed, I have a lot more samples here: https://drive.google.com/open?id=1qYwuu ... W9lJZDlXwA

By the way, you should also check here if you are looking for models: http://forum.xentax.com/viewtopic.php?f=16&t=17656
