[Android] Oshiro Project RE : ATX files extraction (DMM)

[Shiruba]

This is a (ecchi) tower-defense game by DMM for browser and Android (see this link for more info).

The files of this game are .ogg for voices and .aar for everything else. The .aar are extractable with this script, and creates .atx with other .aod or .atb files. The main data is in the .atx files, although I found nothing helpful on these atx files (which have to be images / textures). The first bytes are "ALLZ" but I didn't managed to go further than this. So feel free to help if you are familiar with these files.

 

Here is the download link for some of the game's files. I've provided the alar.bms script to extract the .aar files, the original .aar files and the output files (each in their own folder) from these .aar files after using the alar.bms script : https://drive.google.com/file/d/1_yNv56qW61FwJFMCoPusRn4AphpPmp36/view?usp=sharing

"ALLZ" is a signature for Aqualead LZSS compression method. It is used in few other game as well.
You can use this tool to decompress https://drive.google.com/file/d/1J8r0xxecTXYLiZ9klkD7lQzJ06djMAbs/view

And then you can use ImageHeat to view texture data:
