Mobile Game Asset Download

[chrrox]

This tutorial Will show you how to download all the assets from a mobile game instead of
having to play the game and the game only downloads the assets when you see them in game.
What you need for this tutorial is
Nox App Player: https://www.bignox.com/
Process Hacker: http://processhacker.sourceforge.net/
Telerik Fiddler : https://www.telerik.com/download/fiddler
and the apk for the game you want to get the assets from.
We will use 放課後ガールズトライブ aka Girls Tribe After School.
Apk Download
Start up nox and get your google account all set up.
Now drag the apk onto the home screen and this will pop up.

click open apk folder
now click on the game and choose install.
Now we need to start up fiddler and go to tools options and set it like this.

Also make sure the check mark under Connections for Allow remote computers to connect is set.
Now you can download the certificate from http://127.0.0.1:8888

Copy the certificate you downloaded to Nox_share\Other folder.
use ex file explorer to copy the certificate to /sdcard
Now go into settings -> Security -> Install from sd card

Click FiddlerRoot.cer and just give it a name and click ok

Now we can point nox to our fiddler proxy.
Go to Settings - > Wifi - Click and hold on the wifi connection and choose modify network

Make sure your computer can be accessed from the internet on port 8888 (Normally called port forwarding)
and set the proxy like this (Get it from http://whatismyip.com )

Now if you launch the game you will see url's start to show up in fiddler.
the first 3 are

http://game.jp.girls-tribe.com/system/get_game_version
http://game.jp.girls-tribe.com/system/resource_version
http://res.jp.girls-tribe.com/Resource/ ... c.csv?key=
We are interested in the 3rd one.
if we paste this in a browser we get a nice csv list of all files.
example entry
release_1.0.7/Android_Compressed/AssetBundle/Character,ch_nadeko_maid_00_body,a3a6ae8682cac7113ff236f479d4df84f22cff5b,
With this we can generate the download link for our computer to grab the file.
http://res.jp.girls-tribe.com/Resource/ ... 84f22cff5b
so the download format is
release_1.0.7/Android_Compressed/AssetBundle/Character, - path
ch_nadeko_maid_00_body, - file
a3a6ae8682cac7113ff236f479d4df84f22cff5b, - key
so we do
http://res.jp.girls-tribe.com/Resource/ + path + file + ?key= + key
you can get the ios version of the files also with this csv file.
http://res.jp.girls-tribe.com/Resource/ ... c.csv?key=

For some games you might not see url's in fiddler (some games use tunnels)
for those games just see where the tunnel is connecting to example might be
tunneling to res.jp.girls-tribe.com:443
just open up Process Hacker (as admin) While the game is paused downloading files
and right click noxvmhandle.exe and go to properties
click on the memory tab and choose strings

after it comes back with all the strings choose filter
and put in girls-tribe.com
and it will show you the games links even if they were hidden.

Doesnt work with DoriSupi (a.k.a Drift Spirits) , this app dont have .csv

[chrrox]

It does have a csv file.
It was inside a unity file (first file it downloads)
just extracted it and got this.
http://s3-ap-northeast-1.amazonaws.com/ ... 0077605720
http://s3-ap-northeast-1.amazonaws.com/ ... 0086273720
This is the first thing logged in fiddler for the game. (these are the csv files)

some example file downloads logged.
http://s3-ap-northeast-1.amazonaws.com/ ... 9355145860
http://s3-ap-northeast-1.amazonaws.com/ ... 9365232890

Thanks a lot for the explanation @chrrox, I've downloaded every file from "s3-ap-northeast-1.amazonaws.com" and forget the ones with Unicode text , but how set to download the files?

I can't download any file with the csv list, or maybe I'm doing something wrong

Python 3.6 script to download

THE iDOLM@STER Cinderella Girls: Starlight Stage

follow this guide to get your csv file
viewtopic.php?f=16&t=15582&start=30
Then use this python script to have it download all files on pc.
You can edit the script to download ios or android files by un commenting the script.
just make sure your command prompt directory and the csv file are the same folder.

[chrrox]

Here is a script that will auto decompress the files for you.
you need to do pip install lz4 for this script to work.

[mikulover39]

I managed to get what I think is the csv for idolm@ster million live

Code: Select all

http://td-assets.bn765.com/1/production/5.6/Android/6b976a4c875a1984592a66b621872ce44c944e72.data

Code: Select all

Accept-Encoding: gzip
User-Agent: Dalvik/1.6.0 (Linux; U; Android 4.4.2; HUAWEI GRA-CL00 Build/HUAWEIGRA-CL00)
X-Unity-Version: 5.6.2f1
Connection: Keep-Alive
Host: td-assets.bn765.com

I can see the file names inside but it doesn't look like a conventional csv file

[Supurreme]

So once we have all the unity3d files downloaded, what do we do with them? i cant seem to get anything out of them with unity studio

[Supurreme]

wait was i even supposed to get .unity3d files or did i mess up somewhere?

[jpnvrh]

Here is a script that will auto decompress the files for you.
you need to do pip install lz4 for this script to work.

[chrrox]

just remove any python you have installed.
then install https://www.python.org/downloads/release/python-361/
to c:\python36
then open a command prompt
change to the directory
C:\Python36\Scripts
and type
pip install lz4.
The errors you got have nothing to do with the scripts I made just a problem with your install of python.
you can always use the non lz4 script and decompress the files after.
