Fire Emblem Heroes Wiki:Extracting game assets

Normal method
On an Android device, the files the game uses are located in two locations, the  file and in the app's data directory.

The  file is located at   (this path may differ slightly depending on the Android version, to get the exact path for your Android version run   in the Android shell).

The app's data directory stores all the downloaded game files, which is where the majority of game assets will be located. This is located at.

To gain access to any of these directories, you will need root access on your device to do so.

Installing
It is also possible to obtain the game files without a rooted device, using an Android emulator. The following instructions are for Windows:
 * 1) Uninstall your previous installation of MEMU
 * 2) Install MEMU following this guide https://serenesforest.net/forums/index.php?/topic/81087-how-to-play-feh-on-pc-windows-only/
 * 3) Start the new virtual machine then click on the cogwheel and generate a new IMEI, telephone number and change the phone operator. Click on save before switching tabs
 * 4) Optionally change the number of CPU cores and RAM dedicated to the virtual machine
 * 5) 
 * 6) Reboot the virtual machine
 * 7) On the android preferences make sure your time/timezone settings match where do you live (the game will not start with incorrect time/timezone). If you still have trouble with the timezone try disabling the automatic timezone from internet
 * 8) Install the game
 * 9) Start the game, the game will start downloading something small
 * 10) Play the tutorial, once the tutorial is finished, the game will start downloading all the game files

Using the emulator directly

 * 1) In order to access the game files, start ES file explorer/mixplorer, give it root permissions and go to
 * 2) If you want those files outside the virtual machine, copy the folder in   then on windows go to

Using 7-Zip

 * 1) Download the latest version of 7-Zip
 * 2) Open Windows Explorer.
 * 3) Navigate to  . The path might be different if you have installed MEmu to a different folder, or changed the path to MEmu image files in Multi-MEmu.
 * 4) Open   using 7-Zip.
 * 5) Double click the   file.
 * 6) Navigate to
 * 7) Now you can just extract   folder, or navigate deeper and extract any file you want.

OSFMount and ext2fsd
In this method, instead of using 7-Zip, we will use OSFMount to mount the .vmdk file and and ext2fsd to read Ext4 partitions from Windows. OSFMount also supports command line interface.
 * 1) Download and install OSFMount and Ext2Fsd
 * 2) Open OSFMount, click Mount new...
 * 3) Click ..., and open
 * 4) Choose Partition 2, and click OK.
 * 5) Now you can access the game files in
 * 6) To unmount, select the mounted drive in the main window of OSFMount, then click Dismount.

File structure
All files with a  extension are actually WebP files, despite having a png extension. The official converter for webp files is dwebp.

The files with a  are xor encrypted lz77 files. You may use FEHDataExtractor to view most of the games' internal data such as Sacred Seals, Forging Bonds, and unit stats.
