Idola Phantasy Star Saga Shutdown--Ripping Help needed!

[GonneFishin]

Hi, I'm new here, (don't know where to post) but I'm extremely interested in games preservation. I know preserving mobile gacha games is generally frowned upon due to the nature of the genre but I feel like this one deserves special attention.

Idola - Phantasy Star Saga, may not have had the highest player count, but with it being a subsidary from Phantasy Star, I'd love to make sure it and its characters and music at least are remembered as part of the series.

The reason I'm posting this asking for help is due in part to an issue with the apk. When you install this game through an apk, the game makes you install extra data. I am ASSUMING a large chunk of the game's artwork and content is in this installation data. Is there any possible way I could rip from this through bluestacks or another tool? The apk itself is quite barren as far as I've looked over. What IS there has strange file extentions I've never seen before, like acb and awb... 

If anyone is able to help or wants to join me on this project... It's quite time sensitive. The in-game server will shut down on Aug. 22, 2022 and with it, I assume, the extra download data.

the latter one handles a different game, but can probaly give some pointers about tools and folder structures.

from what I know, you definitely need a rooted android phone and an internet connection to the game. usually it's the cache folder where you find the juicy bits.
