POPOPO Store Dataset

This dataset contains items collected from the POPOPO store. It includes metadata and PNG images for 1,036 items, along with decrypted UnityFS AssetBundles for five platforms.

Access

This dataset is maintained as a closed, gated resource. Access requests are generally not being accepted, and users should not expect access to be granted. Any exceptions are made solely at the maintainer's discretion.

Submitting an access request does not imply or guarantee approval.

Contents

• dataset.jsonl: normalized metadata and file paths for each item
• items/<item-id>/metadata.json: original item metadata
• items/<item-id>/images/: product images
• items/<item-id>/asset-bundle/<platform>/main: UnityFS AssetBundle
• platform-differences.jsonl: bundle size and hash comparisons across platforms
• files.sha256: SHA-256 inventory of the included files

The supported platforms are windows, mac, linux, android, and ios. The AssetBundles are plaintext UnityFS format 8 files built with Unity 6000.0.61f1.

Loading the dataset

After your Hugging Face account has been granted access, authenticate and load the dataset as follows:

from datasets import load_dataset

dataset = load_dataset("fa0311/popopo-dataset", token=True)
print(dataset["train"][0])

Each record includes fields such as the item ID, name, description, type, price, brand, tags, image paths, and AssetBundle paths for each platform.

Creating a Unity package

tools/create-unity-package.ts converts one item's AssetBundle into an importable .unitypackage. It uses AssetRipper to export the selected bundle, adds the shared dependencies from common/assetripper/, assigns deterministic paths and GUID references, and packages the result. Unity Editor is not required to create the package.

Requirements:

• Node.js 24.12 or later
• AssetRipper GUI Free

Install the Node.js dependency from the dataset root:

npm install

Start AssetRipper.GUI.Free and leave it running, then execute:

node tools/create-unity-package.ts \
  --item-id <item-id> \
  --platform windows \
  --assetripper-url http://127.0.0.1:51111

The supported --platform values are windows, mac, linux, android, and ios. By default, the package is written to:

popopo-unity-packages/<item-id>/<platform>.unitypackage
