Unreal Engine 4 pak-file Unpacker / unreal_tournament_4.bms [UE4 global topic]

[AlphaTwentyThree]

I'm not sure I understand...

The format of these files, they should be opened with Gildor's UE Viewer.

[AlphaTwentyThree]

Ok, thanks. UE Viewer couldn't do the job. :\ I'll open a new topic for this.

[AlphaTwentyThree]

I've found the music but it's located in an unfitting folder: "zombiesoundeffects". Could there be something wrong with the folder structure?
Sorry for bugging about this but I'm checking for bugs this way.

[aluigi]

No, the full filename is read directly from the entry. It's not a nested format (like those with "callfunction EXTRACT").

[AlphaTwentyThree]

Alright, thanks for clearing that up!

[nightwarrior]

Thanks, doesnt work on XOIO - Winter Chalet.. :/

[AlphaTwentyThree]

Here's another one that doesn't work properly: http://*USE_ANOTHER_FILEHOSTING*/4c737a4 ... oEditor.7z
sorry for using multiup, forgot to use another hoster....

[nightwarrior]

No problem, Thanks you so much!

[aluigi]

Script 0.3.1, thanks

[AlphaTwentyThree]

Thank you!

Awesome tool! I'm trying to use it with Street Fighter V on Windows 10 and the tool is crashing though (it never shows any progress and after a while goes to a not responding status).

@patopeixe
Any luck with my script 0.3.1 for quickbms?

Nope

[aluigi]

Can you try also with quickbms_4gb_files.exe?

Then can you upload the files obtained with filecutter.bms?
Probably you have to edit the script with a text editor for increasing the CHUNKSZ variable from 0x100000 to 0x1000000 (one more zero) to have more data.

[patopeixe]

Thanks for the quick replies aluigi!
Here's what I got when I used the quickbms_4gb with the edited filecutter with the extra zero:





i'll upload the files to mediafire or mega and post them

I have updated the script to version 0.3.2 for considering the number of CHUNKS <= 1 as no chunks.
I tested it also with another couple of games and it continues to work correctly.

Now, the problem of this SF5 game is that the archived files are encrypted.
All the .U files have a "157..." header instead of the classical 0xc1832a and it's not possible to decompress the files for this reason.

Hi aluigi I have tried your updated script 0.3.2 for sf5 and have gotten this error

Code: Select all

Last script line before the error or that produced the error:

I understand you have stated the .u files are encrypted but I am more interested in the .ini files. Are those encrypted as well? If they are not is there a method to extract them as they have the code to remap keys in SF5.

Thanks for updating the script! So If I want to obtain the game's 3D models would you suggest I go another route instead of trying to uncompress the .pak?
