priconne-image-extractor

Information

This is a quickly thrown together script that focuses on downloading and extracting image/Texture2D assets from different regions of Princess Connect! Re:Dive's content delivery networks.

The stability of this script is not guaranteed to be stable, and is not guaranteed to be fixed or improved on.

Extracted files may take up a lot of space on your hard drive. Please make sure you have enough space before using this.

REGARDING priconne-jp'S Unity UPDATE (FUTURE MANUAL UPDATES MAY BE NEEDED)

Since priconne-jp's Unity update on April 10th, 2023, SerializedFiles and BundleFiles no longer provide the Unity version being used. Unity may update again in the future, and will break this image extractor again.

UnityPy offers a way to set a UNITY_FALLBACK_VERSION through its config.py file
If this program breaks from another Unity update, you can easily get the Unity version being used if you have the DMM version of the game installed:

  • Locate PrincessConnectReDive.exe in DMM/priconner/ (Open game folder via DMM to locate this path easier)
  • Right-click PrincessConnectReDive.exe and click Properties
  • Under Details tab, see the value under "Product version". Copy and replace this value to config.py's UNITY_FALLBACK_VERSION if needed.

Supported Regions

Requirements

System

  • Node.js v16.16.0 or above
  • Python 3

app.js

deserialize.py

Running The Script

With a command prompt open that's pointing to the directory where all the project files are saved:

node app.js

Auto Image Extracting

As of May 15th, 2023, auto image extracting is available for all servers thanks to the UnityPack -> UnityPy upgrade.

All downloaded unity3d files will automatically be extracted after download process.

config.json

Before you run the script for the first time, it is recommended that you edit the config.json to make sure every thing appears to be in order and you aren't fetching files you don't need. If you choose to download/deserialize everything, the entire process may take a very long time.

Enabling Regions

Regions can be enabled/disabled by switching the enabled value to be true/false

Force Update

Turning force update on will cause files to be redownloaded even if they may be the latest version.

Manifest and Asset Filters (Whitelist/Blacklist)

It is recommended to set this to only files you are interested in before using this script for the first time.

Filters can help you download only specific game assets that you're interested in.

manifests are the "assetmanifest" files that index all files related to their category. e.g. unit2_assetmanifest for unit related assets and storydata2_assetmanifest for any story related assets

assets are the specific individual files in manifests. e.g. files prefixed with unit_icon_unit_ are unit icons for characters.

Add file names that you want to ignore to the blacklist, add file names you only want to focus on to the whitelist.

For example, to only download character unit icons you can set your filter to be as so:

"JP": {
    "blacklist": {
        "manifests": [],
        "assets": []
    },
    "whitelist": {
        "manifests": [
            "unit"
        ],
        "assets": [
            "unit_icon_unit_1"
        ]
    }
},

If you want to whitelist/blacklist multiple files, you can do so like so:

"blacklist": {
    "manifests": [
        "all",
        "storydata"
    ],
    "assets": [
        "unit_icon_shadow_",
        "unit_icon_unit_2"
    ]
}
