Hello, I am trying to get the bin files for the game mentioned above working correctly. When exporting them from unity assets bundle the .acb comes out as a .txt file and I manually change it to the proper .acb as all of the unity extractors extract them in a .txt manner. Though I do run the file through VGM Tool the file still comes out as a garbled mess. In Unitystudio and in unity assets bundler both files are read as a text file.

Link to game:

Initial game Archive reuploaded. This shows a lot more detailed files mainly .MF, .SF., .RSA Files that I haven't seen before.

Main ACB (Used the ACB before it was extracted and the lines look way different)

The .Bin Files that are supposed to convert to .HCA via HCA2WAV

The .HCA File Extracted from via VGM Tool.

No Idea why when I convert it, the sound doesn't work properly. Any suggestions?

Post Edit: Updated to Add some images of the lines via HXD.

Updated : added a Link to the game

You need to find the decryption key for the HCA files in order to decode them correctly.

Dang it, Thank you for the response. So that's why I cannot hear squat.. Any idea on how I can start my search for the decryption key?

I think there is a tool someone has made that can get a readout of the decryption key. Not entirely too sure how to go about it as it's from a japanese coder.

Seems like one has to summon the great Key Decrypter, dang it so close to having the sound effects yet so far away.

Essentially from what I've read about it, you swap out one of the CRI unity runtime libraries in the game files with a modified version of it and then run the game as per normal. When the game runs, it brings up a command prompt display and shows the decryption key in plain-text to see.

Yea, I need to find that seems very useful. Though I will end up uploading all the files I have which can be opened in unity studio. A lot of things like the images work however sounds are just locked off. I just noticed that I had one of the wrong ACB files uploaded. The new ACB that I have had different information in the HxD. Seems the headers start with a @UTF.

Uploaded a converted APK which holds new files originally not in the first upload. The key might be in one of them.

Hey, Aluigi do you know what I am missing possibly or what I should even look for? I believe the encryption is in a file but I wouldn't know what it looks like.
