Hello everyone, hope you are having a great day today.

While I do know that there was a topic about Fate/Grand Order files here in the forums, it didn't advance much and I hope to explain in detail on what I currently know to hope some kind people can help out.

There are about 3 kinds of FGO game files in the games assets folder: the .cpk, the .bin and the .txt file. The main concern is the .bin files, as the .cpk files can be unpacked (using the .cpk unpacker) and can be decrypted when using the key found here for the audio files of the game.

From what I know about the .bin files, I read up that someone that used to work on the encrypt files that the .bin files need to be converted from .bin to .3dunity files, then using something like the Unity Assets Bundle Extractor to then get the decrypted files. Sadly, I don't know where to go off going from .bin to converting to .3dunity files, if someone could help, that would be appreciated.

At best, I've only been able to get some assets files from doing NOX ripping using ninjaripper, having a google drive for what I have uploaded so far, even doing some sprite work from it as well, as shown here (I do help with the wiki/wikia side of FGO for sprite work). But I know that ripping the files is not enough, as there are some texture and other stuff still within the game files that can't be ripped using ninjaripper and is the reason I am asking for help, mostly wanting to help people to get some of the game's file texture (I do want the files to be available to anyone that wants to look at in a google drive folder).

While this might not be needed, a file here explains a bit of what unity assets FGO uses, such as: PlayMaker, uSequencer, NGUI, UniWebView2. There is a bit more detail in the .pdf file but it is mostly Japanese, so try what you can make of it if you do check it out.

I tried my best to keep it short, sweet and to the point to not bore people with too much text to read, and if you choose not to help, that's perfectly fine, I'm more glad you took the time to read my post. Even if there is no way to decrpyt the files, if something like unlocking all the game's servants and CE that then be ripped using ninjaripper, that would also be fine, if not, I will try to work on decryption myself, but hope that some kind people give me some tips on how to approach the encrypted files. For now, I have three files if anyone wants to check them out.

Thank you once again for taking the time on reading this.

Edit: I've upload some files that are inside the .APK of FGO at a google drive
