Obtaining the Assets

Android

The assets are located in the following folder and require a rooted Android phone to view the contents:

/data/data/com.nintendo.zaga/files/assets

Note that Dragalia Lost will block access to the game if it detects root, so root your phone at your own risk.

iOS

The assets are located in:

Payload/zaga.app/Data/Raw/PreinResource/AssetBundle

Extracting the Assets

The assets can be extracted using any Unity asset extractor, such as AssetStudio.

AssetStudio

1. Go to File > Load Folder
2. Select the folder where the asset are located.
3. Wait for AssetStudio to finish loading the files.
4. Go to Asset List tab.
5. Select the assets you would like to export (or skip to next step if you would like to extract everything).
   1. It is recommended to go to Filter Type, and select the asset types you would like to extract. The types the Wiki usually extracts are:
      1. Texture2D - Character images, icons, backgrounds, model textures, etc. Basically any and all images in the game.
      2. Mesh - 3D models and objects
      3. MonoBehavior - Text and data including story script transitions, character data, etc. As well as a lot of unreadable junk data.
      4. Sprite - Similar to Texture2D, but sometimes has icons cut out (vs. Texture2D putting all the icons into one UI file which need to be cut out).
6. Go to Export > All assets / Selected assets / Filtered assets to export and save the assets.

Asset Type Details

Texture2D

Texture2D images are often split into separate images, and in order to get them into their proper formats as seen in-game, other tools are needed to combine these images such as Python, Imagemagick, or Matlab. Chu2038 also created a script to process these assets and label them with a category.

YCbCr

Several of the image files in the Texture2D folder are files split into their YCbCr channels. The following include code snippets on how to convert these split YCbCr images into one properly colored image.

For example, Karl's character image is split into the following files:

• 110008_01_r04_Y.png
• 110008_01_r04_Cb.png
• 110008_01_r04_Cr.png

Python

• Requires Python Pillow (Python Imaging Library)

from PIL import Image

base_file_name = "110008_01_r04"
(z,z,z,y) = Image.open(base_file_name + "_Y.png").convert('RGBA').split()
u = Image.open(base_file_name + "_Cb.png").convert('L').resize((1024,1024), Image.LANCZOS)
v = Image.open(base_file_name + "_Cr.png").convert('L').resize((1024,1024), Image.LANCZOS)

merged = Image.merge("YCbCr", (y,u,v)).convert('RGB')
merged.save("file save location here")

ImageMagick

magick convert 110008_01_r04_Y.png -colorspace YCbCr -separate ysplit.png

magick convert ysplit-3.png 110008_01_r04_Cb.png 110008_01_r04_Cr.png -set colorspace YCbCr -combine -colorspace sRGB combined.png

Matlab

• Note that Matlab requires a paid license to use outside of the 30-day free trial.

image1 = imread('110008_01_r04_Y.png');
image2 = imread('110008_01_r04_Cb.png');
image3 = imread('110008_01_r04_Cr.png');
image2 = imresize(image2, 2);
image3 = imresize(image3, 2);
y = image1(:,:,1);
b = image2(:,:,2);
r = image3(:,:,3);
B = cat(3,y,b,r);
B1 = ycbcr2rgb(B);
imshow(B1);

Alpha

Many of the Texture2D images are not transparent, but have their alpha files separated into another file. These files can be identified if they have an _alphaA8, _A, _alpha, or _Alpha at the end of the file name. Similar to YCbCr, you will need separate tools to combine the original image and the alpha image.

Additionally, note that there are two different ways for the alpha file to be combined depending on the alpha image.

Python

Method 1:

from PIL import Image

base_file_name = "100029_02_r05.png"
alpha_file_name = "100029_02_r05_alphaA8.png"

(r,g,b,z) = Image.open(base_file_name).convert('RGBA').split()
(z,z,z,a) = Image.open(alpha_file_name).resize((w,h), Image.LANCZOS).split()

merged = Image.merge("RGBA", (r,g,b,a))
merged.save("file save location here")

Method 2:

from PIL import Image

base_file_name = "101401_IMG_03_base_01.png"
alpha_file_name = "101401_IMG_03_base_01_alpha.png"

(r,g,b,z) = Image.open(base_file_name).convert('RGBA').split()
a = Image.open(alpha_file_name).resize((w,h), Image.LANCZOS).convert('L')

merged = Image.merge("RGBA", (r,g,b,a))
merged.save("file save location here")
