Hi all,

First, thank you for making bms script, especially for aluigi.

I'm new in this "game", so I'm trying to understand little by little by read and googling, but it seems I'm deadlocked

And here I'm, hope that somebody can help me in the forum

What I need :
Extracted sound files from obb data including file names on each sound

What I have done :
Use quickbms with vainglory bms (got 2 .dat files and I don't know what can I do to that files )
change obb data to zip and extract
use droid (digital record object identification)

Problem:
Now I can see where the sound files and change the extensions to .mp3 manually and it work, but the file name is to messy
So, How to get sound files from obb data including file names on each sound?

Sorry for bad english & Thanks

There are no filenames stored in the vainglory archive.

Hi aluigi,

After I search, I found interesting post here : Reddit

That's the wrong question.
The rigth question is: how Sounds/Tutorial/en/Announcer_Enemy_Turret_Destroyed.mp3 become 1522b92e47a0c135c072e85ad3f43915?
The answer is: that's the md5 hash of the filenames.
Some archives don't store the original filenames, they store their hash (sha1, md5, 32 and 64bit hash/crc and so on).
And the answer to your next question is: no, you can't get the original filename from the hash

thats too bad, because I imagine they stored the original file names to apk and some script from apk call obb data file. Thats why i also includes apk file above.

I already try to contact the OP on reddit, but it seems he not active anymore on there.

Can you please pm me aluigi? I want to ask you something If you do not mind
