Hi fellow /jp/s.
I'm nibbling at BSZ and wonder if I could get some help from coders/hackers.
It's on Unity, but with NexAS engine(which they apparently used for BS and other games) merged inside. Well, except this time they didn't put script next to other archives containing CG,BGM,SE etc. Using Process Monitor I figured that the script seems to be in .asset files with strange long names https://imgur.com/a/2TpJu (no, it's not .assetS, it's .asset. Opened it with hex editor and saw the line "CustomAssetBundle" so there seems to be a special way to read it inside the dlls)
I used DotPeek to decompile dlls in the Managed folder and found some classes/functions that seem to be related to that.
Also, I found out that settings are being encrypted+serialised/decrypted+deserialized using standard unity library. https://imgur.com/a/OpRe4 However, it doesn't seem that .asset files are. There is some gibberish, some code and even assembler commands here, all unecrypted. https://imgur.com/a/XH3CA
I am not a total noob in coding, but this is a bit complicated for me to track down.
Would anyone be willing to take a peek and maybe give me a hint?
