Watch Dogs: Legion .dat .fat archives

[ExQualityZ]

Game is ready to preload right now, i guess someone could look into the dat archives?

[CobraGamer]

The archives are still in roughly the same format that WD2 had, but the compression method has changed. Is anyone willing to look into it, so that we're able to unpack / repack the archives?

[Ekey]

I don't have a game and can't check it, but probably files must be compressed by Oodle

In fact it's a old engine with version 13 is used, the previous one was 11. I changed the version for Legion in my old Explorer and it works fine.



I think Sir Kane can fix their toolkit for Legion.

[ExQualityZ]

Damn you should release that explorer, didn't know something like that even exists and it looks like a very handy tool

[Ekey]

I did not make this tool for extracting or packing files, but only for convenient viewing of root directories and correct parsing of offset, compressed size and uncompressed size values. Usually all my tools are just console ones. In this case, I see no reason to do what is already there, it's just that Sir Kane needs to make some changes in his toolkit for WD2 and it will be works fine for unpack and pack it back.

Also i don’t know yet what about data compression. Probably newest compression used > OOdle???

If i understand correctly, they did not include the executable file with the libraries in the preload, right?

Well, okay. I'll check OOdle compression later.

[Ekey]

Okay, here patched in two bytes version of WD2Extractor for Legion.

Mirror 1
Mirror 2
Mirror 3

Have fun

[CobraGamer]

Thank you, I really appreciate your work!

[Lord Vaako]

Great job Ekey! Thank you!
Could you share some info how you did it? What kind of compression is it, etc?

Edit:

Just noticed " here patched in two bytes"

btw. What do you use to view xbg files? the tool I used for WD2 (plugin for UU3D) doesn't work

Here's version 1.0 of WdlExtract:
