For video files do not use bpk (crc error). Just use m1 or something similar.

Decompressed fine with Xtool v0.39 + oo2core_8_win64.dll

Hi! I'm new at game conversion. Is anyone know the best method to compress Sea of Thieves? And any tips for me as I am a beginner?

@jihack
Maybe precompress with zlib because of UE4 engine (most of cases).
Could be that the files are encrypted.

Send me a sample .pak file

Decryption key should be 0x37A0BC3DC2E01D9EB4923CA266A5701F56A4802347F07927 FC3FC25C93B31B50

Yep I tried with some *.pak files with that eas key from rin but the ratio still 90%+. The tool I use is DiskPan GUI from Cesar82. I'll send the .pak file in pm.

Well, here's the paks file https://drive.google.com/file/d/1A2y...ew?usp=sharing
Bcs I can't pm anyone

Maybe there is just "bad" data inside the files, hence the worse ratio.

What algorithms should be used to process SpellForce 3: Reforced?

[shazzla]

Good ideas to start :

1. Look for compression/encryption algorithm names in folder structure.
2. In Total Commander ,view the main gamefiles and its DLLs (F3) and search for comp/encr-algonames,too.
3. If none of them found ,try zlib ,maybe it works.
4. If zlib doesnt work,give it up!

For dds, you can use just srep+lolz
ogv are video files, try to use a low freearc setting (m1, m2) or just use m0 for storing (sometimes you can compress video files, but just a few mb)
lvl, crf I don't know

As for "bin_addons_win32/SF3_Campaign/package.pak_data" you can try zlib

srep+lolz/lzma - devs didn't use compression on their paks.
