Need help on some specific BLK files

[OshidaBCF]

Hi, i was wondering how you implemented the extraction for the blk related to user data, neither kotiq's not klensy's tool work on it so maybe you implemented something that they didn't

this is the packed file
35129386.txt

and this is what your tool output
35129386.txt

So it works properly but we're trying to understand it

is it different from regular blk, if yes, how

Hi @OshidaBCF

It seems like a regular blk file. My project is fully based off theirs, so maybe some of their new methods are not compatible with this file, just a guess.

Here are some values I got from debugging, hopefully it helps find discrepancies:

Property	Offset	Size (bytes)	Count (entries)
String map	0x1	0x5afa	0x457
Large values	0x5b0d	0x5f	------
Parameters	0x5d70	------	0x20f5
Blocks	0x16518	------	0x7a8

this is the packed file 35129386.txt

@OshidaBCF How did you managed to get that packed profile file?

@OshidaBCF How did you managed to get that packed profile file?

There's an API you can call and if you pass the user ID you get some "public" info about the account, don't dream, there's not password or anything

Basically you can get the very same data as if you checked an account in game

I don't remember exactly where i got it

In python using Request you can use this

headers = {
      'action': 'ano_get_public_userstat',
      'gameVersion': 'latestGameVersion',
      'comprTypes': '',
      'internalIp': '192.168.1.30',
      'platform': 'PC',
      'platform_id': '2',
      'userid': 'userIDyouwanttocheck',
      'uidHint': 'yourIDforsomereason',
      'rpver': '190865',
      'rsati': '26306@6E8A61D2982AAA0F764B0399F0974454',
      'rpsui': '26306',
      'Content-Type': 'application/octet-stream',
      'transactid': '8159729706243833646',
      'Expect': '',
      'token': 'secretWTWikiToken'
    }
    response = requests.post('https://char-lw-nl-005-2.warthunder.com/char', headers=headers)```

@OshidaBCF since I already have you here..
I'm working on a new revision right now, but before I publish anything I wanted to check in with someone who uses it regularly:

• What tool are you currently using?
• What features are you looking for in a tool?
• What features you would like to have, but nok of the tools offer them?

[OshidaBCF]

Currently we are used FlareFlo's WT Unpacker that you can find here https://github.com/Warthunder-Open-Source-Foundation/wt_ext_cli

it's made in rust and he used yours, kotics and klensy tools to make his own

I can't remember every features that it has that other tools lacked, but the main one is Multithreading i think

5.9 seconds to unpack all 10 vromfs (it's less than 1 second on his computer but he has something special)

Currently he is trying to add is a way to automatically convert avif images to DDs

Another feature in his tool is dxp/grp unpacking (just the names, not the actual content)

The tool doesn't support replays files as we never really found the format the files are in

so to answer your questions quickly

• FlareFlo's Unpacker
• Multithreading, DXP/GRP Unpacking
• Replay Unpacking (i think your tool doesn't work on them anymore

Although i would suggest instead of remaking your tool on your side you could "perhaps" work with flare, especially if you know some stuff we don't, so i invite you to join the Official Datamining Server, when you join ping me (Oshida) or Gszabi
