One Piece: Burning Will (航海王:燃燒意志) Unity3d File Help

[Roselle]

This is a compressed package of unit files. The files are encrypted. I haven't found any useful information in the files. I hope I can get some help.

This is a compressed package of unit files. The files are encrypted. I haven't found any useful information in the files. I hope I can get some help.

There are two files in this package. One is encrypted and the other is unencrypted, which can be read and edited. I hope to get some help.

The burning will is XORed with a header of 61 or 67. The header is simple, but the problem is later.

I do not know the regularity, but XOR is performed from the middle to the end.
Decryption is difficult because you don't know the rules from which byte to XOR.

I think you should put the name of the game in the thread title.

I found that some unit encryption and encrypted containment are basically the same, which makes viewing more difficult.

is there any progress? I hope Mr @Chrrox can help,,

[chrrox]

Here is a python scrip to decrypt these files.
Use python 3.8
do pip install lz4 first.
copy the 2 files into the python folder.
drag the folder you want decrypted onto the bat file.

thank so much, does this work for all encrypted files in this game?

[qowiiskandar]

i get error (sorry im noob)

[einherjar007]

Thanks a million, chrrox!
I'm really happy because I was interested in the assets of this game. Thank you!

i get error (sorry im noob)

I tested it with the file shown in the screenshot and it decrypt successfully.
Did you do "pip install lz4"?

Also, deep directory hierarchies may not be good. Why not put the file you want to decrypt into the newly created directory in the python directory and drag and drop it into op.bat?

wow successful, mr chrrox is cool
thank you for the advice @einherjar007

by the way, what plugin to open unity3d files in noesis?

edit:

you know? This game in the previous version has not been encrypted, to be precise in version v1.3.0.159754 it hasn't been encrypted, but after kittynhidding from deviantart unpacks this game , the later versions are all encrypted, I tried it, I think the title on this tread should be changed again,

[qowiiskandar]

How are you? I have another problem, I try to open the extracted file .unity3d which contains audio file using assetstudio by perfare but it doesn't produce anything, if it contains 3d files there is no problem, can anyone help?

Someone helps me!
I have used the Utinyripper and DevX-GameRecovery to unpack the assets bundle of One Piece: Burning Will (航海王:燃燒意志)
About prefab, model, mesh, texture... everything after unpacking is correct and usable. However, the animation of the models is incorrect after unpacking. It seems like the keyframe is missing or wrong.
Ex:

I hope you can help me find a solution to fix this error.
Looking forward to your response as soon as possible.

Thanks and best regards.

Try to use AssetStudio and export the prefab+selected animation. I've usually solved those weird looking animation this way, dunno what's cause them to be importer badly with DevX~

SOMEONE HELPS ME PLEASE! Mr chrrox or other member

Previously in the beta version this game I can ripping it, but after this game was released it was encrypted,

i need help i am trying to extract the file from One Piece: Burning Will (航海王:燃燒意志) apk version 2.3 and i have something like this


i probably did something wrong, it try AssetStudio but i never use it before please help me

Encryption in latest chinese versions is still the same, which is one byte xor with different bytes for different compressed chunks from the same bundle - they're just changing bytes set between versions. Though even with properly decrypted chunks bundles doesn't work in AssetStudio, apparently they've changed something else.

Test script in the attachment. If you want to validate current set of xor bytes, uncomment and use clog command instead of log (marked "for tests"), this way chunks will be decompressed in output files and you'll get an error in case of incompatible set or other issues.

Now you can also download modified AssetStudio with support for the game (link), and open bundles directly without converting them. It should be also compatible with old game versions and with chinese versions of Devil May Cry: Peak of Combat.

Update: Script is updated with fix for compression flags, they're modified in output for compatibility with AssetStudio.
Update 2: Script is updated to support uncompressed chunks in bundles.
Update 3: Modified AssetStudio build with direct support for the game is added to the post.

[einherjar007]

Thanks, spiritovod, it certainly works!
The one thing that has been tweaked in the bundle file is the compression type - 0x03 has been rewritten as 0x05. Depending on the file, there are differences in the location and number of pieces to be replaced.

I think it would be quicker to rewrite AssetStudio, adding 5 to case : in the ReadBlocksInfoAndDirectory in AssetStudio/BundleFile.cs would make it readable.

[einherjar007]

List of files that fail to decrypt. The game cannot be launched with Chinese authentication, so we checked only by the contents of the apk.

*Edit
There were a few files that did not generate errors with bms decryption, but probably failed to decrypt. upload the list as filelist_noerror_fail.zip.

[spiritovod]

@einherjar007: Thanks for explanation, so that field is compression flag. I've updated the script, now output would be compatible with AssetStudio without additional modifications if possible.
As for the rest - the script is using workaround, which shouldn't be used to begin with. But it's not possible to use the same approach as original python script, because quickbms can't catch exceptions. Not sure if it can be processed properly in quickbms without reversing how encryption is actually applied to avoid workaround (something like rotation of used bytes based on hashed names).

Update: Another small update for the script, apparently there are uncompressed chunks within some bundles, they're now handled properly.
