[Unity3D] Punishing : Gray Raven assets

Post by Kanbara » Mon Jul 27, 2020 7:16 am

Recently, this game's assets have been encrypted.
As far as I know, this game is made by unity3d (2018.4.23f1) and it is an Android mobile game.

It's 3D models and illustrations are really exquisite. I really want to rip its models from this game's assets but I came out fruitless after using AssetStudio, AssetsBundleExtractor, disunity etc..
I do hope someone nice can help me figure this out!! :D
Thanks!!

And here are some samples from this game (2MB)

Use this quickbms script batch process all assets.then AssetStudio will recognize them.

Code: Select all

get ArcName filename
set Name string "new\\"
string Name + ArcName
get Size asize
math Size - 0x04
log Name 0x04 Size

Thanks for your effort!
But it doesn't work on my part.
I think this script you made is mainly for this game's previous version. I know we can simply delete the "Kuro" before the "UnityFS" before.However, the latest version of this game has changed it encryption way and I totally got no clue of if :(
and it seems quite complicated to decrypt since it's data is irregular and messing around.
Anyway, heartfeltly thanks for your replies! :D

The latest version I installed from taptap today was not encrypted.
It's neither a kuro header nor another encryption. It was a regular unity3d file.

By the way, the second-type encryption method seems to be same in "castlevania moonlight rhapsody".
Add 70 bytes of dummy data and rewrite random bytes. I have no idea on how it will be decrypted.

Yeah, I've asked some people specialized in decrypting Unity3d assets but they gave the same answer as yours--dummy and random bytes added.
But glad to know the game from taptap isn't encrypted and do hope that this game could be popular in the world! It's really a good game and the characters' skins as well as 2D portraits are fabulous :]
