Is it possible?

Post by otomon »

Hey, sorry if my question sound really dumb to the pros here, I am a total n00b who have a goal.
I want to preserve a mobile only game in someway because I love it, but I know the publisher (Bandai Namco) is greedy af and will cancel it at anytime.
So my goal is to atleast save the cutscene for future generations... I have 0 knowledge of how Android works but I spent the past few days trying to figure it out what I could do...

For some reason, the game downloads the files in what seems to be an encrypted format, then when you watch a cutscene, it will convert it to .mp4 and place it on a separate cache subfolder, however it has no voice or subtitles as the game is multilingual, therefore it plays the audio track and subtitles on top of the .mp4

I located the file for the subtitle, which when opened in notepad, gave me gibberish, however the first like did tell me it was made in whatever "UnityFS 5.x.x 2019.4.16f1" is.... I looked around the forum and I saw a thread that said to use "UABEA" when I tried to open the file which told me "This bundle is compressed" and after decompressing to a file and going to "Info", the app indeed recognized it was a "Textpack" but then.. what? How do I view the actual contents? Like the actual words in the subtitles. And furthermore, in theory would it be possible to use this app (or any other) to convert the audio track to a workable one?

Would really appreciate if anyone gave me sort of clues.. thanks

What part of my post confused you?

TL:DR I want to know if in theory I can extract and play audio/subtitle files if they are UnityFS .bundle files. from a mobile game.

EDIT: I kept searching around the forum and it turns out what I needed all along was an app called "AssetStudio".....so I finally managed to figured it out, but now the issue is that rather than being a continues track, the voice track is a series of smaller voice samples x_x
