(Unity) MHA Ultra Impact compressed files

Post by condemn »

Hey guys, I was trying to open theses files in Asset Studio but it doesn't load.

I searched and found in the game's copyrights that they are using k4os.lz4 compression, unfortunately I'm no expert when it comes to this.

I would glady appreciate if anyone has an idea/solution to it. Thanks for your time !

They're using simple xor encryption for assets. Here is script for decrypting them.

Also, for search indexing it's My Hero Academia: Ultra Impact.
