@CriticalError: I don't have any problems with all of my samples and respective script. Though I didn't download the whole game, so some exceptions are quite possible. Without more samples it's hard to tell anything.

In my case it fails with the third one (pak_11 and a couple others), directly from the android version, the first 2 files extract just fine with the "specific" script, however, funny thing, it only works if I use the 4gb version of qbms (and each file is just a few hundred MB in size), with the other one the first 2 files fail with the same message . . . so it's probably just a memory allocation issue.

Let me know if you need specific samples so I can upload them.

Also, there is a trick to get "some" version of all the files, looking for the app's apk and extracting it you get a 1.9GB file called main.obb.png (which is just a zip file), extract that and look for another file called pakchunk0-Android_ASTC.pak which is also nearly 1.9 GB; that one will work with the AES key, the 4GB version of qbms and it contains ALL the files (except recent updates I think).

@Asciigdl: You can start with uploading those paks you have problem with, I'll check them.

Update: Thanks for the samples, Miracle 2 script updated in the specific scripts bundle.

From which version belongs al those paks? because I got only 1 big Pak and not different one as in your case.

Anyway I confirm, using quickbms it works very well ( on big pak )

Hey guys, there was few days a Beta for Racing Master and this is a Android smaller PAK of the beta, i cant seem to be bale to extract it, or tell if its encrypted, can anyone please take a look?


EDIT: It seems is packed using Zlib? Still not sure how to extract it, might not be encrypted at all.

@cyberspeed: The format itself is quite simple, I can easily modify existing script for it, but index and presumably all uassets are encrypted, while game library is protected with NetHTProtect, so you can't simply analyze or dump it. There is also possibility that the key is stored in non-usual format or encryption itself if non-standard. Unless someone is willing to provide proper key or properly dumped library, I'm not going to dig into it further.
Complementary files (uexp/ubulk) are not encrypted though, but considering engine specifics you can only extract raw textures data from them at best.

Ah, damn, that sucks, the game cant even be ran on a emulator, even devs admitted that, I'm assuming there's no other way to get this thing extracted/decrypted properly, only hope is a Android phone since on iOS that's truly impossible.
If I'd know how to dump what you need as i would have, unfortunately don't know anything about this.

spiritovod, posted Fri Apr 23, 2021 5:19 pm (63534)

@cyberspeed: Actually, any dump will be fine to check if the game is storing key in standard form. Otherwise proper dump would be required for proper analysis. I just don't have any device, compatible with the game, so I can't do anything, even if I want to.

------------------------------------------------------

All "get_hashes" scripts from custom scripts bundle updated to avoid known bug in latest version of quickbms (which is now 0.11).

unreal_tournament_4_0.4.26_paks_only script is also updated. It can now skips assets which are being addressed outside current package. Not sure if it's related to new respective feature from 4.26 or not.
If you'll have more than 0 skipped files with the updated script, please let me know - it will be written after the end of extraction process (except Tower of Fantasy, I'm already aware of it). Thanks in advance.

@brookeantoinette72: As far as I know, all LIS games are not encrypted and not obfuscated. Provide more details about problems with them.

@Ekey: If you want to help, please redirect people to the list at rin forums instead of posting keys directly. I'm ignoring such requests here on purpose, so people could learn where to find them and keep this topic for actually relevant questions about pak format and bms scripts.

@Lord Vaako: The game is using unusual pattern for control bytes at index. I'll try to resolve it in a proper way for possible usage in umodel, but it will take some time, since I'm not good with bit shifts and such. For now you can grab temporary workaround from specific scripts bundle.

@pipindor666: You should use 4.26 script for 4.26 games, it's available via my signature. The key itself is correct.

I'm attempting to unpack the .pak files in the UE4 title "Chernobylite" using QuickBMS, however, using Luigi's UE4 unpacking scripts (UE4.25, UE4.25b & UE4.26) to unpack "pakchunk0-WindowsNoEditor.pak" results in a failure, regardless of whether or not quickbms.exe or quickbms_4gb_files.exe are used.

I believe this error may be due to the fact that pak0 is the only pak file whose size is between 2 GB (maximum of 32-bit signed integer) and 4gb (32-bit unsigned integer), this theory is further supported by the error message notifying the user that QuickBMS is attempting to allocate a negative number of bytes.

My issue however is that I'm not skilled with actually implementing solutions and lack the high-level skills of an individuals here, if anyone could offer any advice as to how to possibly resolve this issue I'd be extremely grateful.

I try use 4.26 script ( unreal_tournament_4_0.4.26b_scavengers.bms ), files started unpacking, but not completely, unpacking just stops in the middle.

Code:

# Unreal Engine 4 - Unreal Tournament 4 (*WindowsNoEditor.pak) (script 0.4.26b)

@GarryOlsen: Provide the pak you have the problem with. If it's one of the biggest (more than 10GB), just upload any small one and error from the biggest.

@pipindor666: You're using wrong script. Specific scripts are for particular games, while you need generic one, which is also available via my signature. Though I don't understand why you've used specific script instead of generic one, it's quite illogical. And please stop posting the whole scripts like that - it looks troublesome and make the page almost unreadable. You can simply mention it (if it's already present in the topic) or attach it as bms or zip files.

Update: Thanks, aluigi, it's much more convenient now.

Thank you @spiritovod. It's enough for me

Btw. do you know a tool to convert DT uassets to any type of "text" file? I tried https://github.com/antoshre/uasset-dt-to-json but it is not working.

@GarryOlsen: I've fixed the issue in the updated 4.26 script, please re-download it.

@Lord Vaako: You can try Fmodel, it can parse some json type assets. But it's not universal solution, since such assets can be significantly customized. In that case the only solution would be creating your own parser.

@spiritovod So I'm using the raw pubg pak extractor script. It extracted fine. When I repack, it works fine.
But then, when I want to re-extract to make more modifications, it gives me this error:

Code:

Info:  algorithm   478
       offset      0000000000e2d96d
       input size  0x000000000000216c 8556
       output size 0x0000000000010000 65536
       result      0xffffffffffffffb8 -72

Error: uncompressed data (-72) bigger than allocated buffer (65536)
       It usually means that data is not compressed or uses another algorithm

Last script line before the error or that produced the error:
  141 clog NAME CHUNK_OFFSET CHUNK_ZSIZE CHUNK_SIZE 0 CHUNK_XSIZE

Any ideas?
