The VG Resource

So I've been exploring ripping One Piece Bounty Rush game. Resources are downloaded into the device with every update so I'm assuming all the data is just in the device. I located an Asset folder in the game, and I used Asset Studio. I was able to find textures and PNG images, but not models or audio. I've already searched if there are other threads on this, and I coudln't find any, so I'm wondering if anyone has any tips on this one?
