🧠 How LemonLoader Identifies Compatible Unity Games on Android Devices

by

LemonLoader’s powerful modding capabilities start with its ability to accurately detect Unity-based games on Android devices — especially VR platforms like the Meta Quest. This process is non-trivial due to Android’s complex application structure, but LemonLoader handles it with a highly effective multi-stage detection system.

📦 1. Scanning Installed Applications via Package Manager

LemonLoader first queries Android’s Package Manager to gather a list of all installed APKs. Each app is identified by its package name (application ID), usually in a format like:

  • com.beatgames.beatsaber
  • com.valvesoftware.steamvr

This gives LemonLoader a list of candidate apps that may be Unity-based.

🧱 2. Detecting Unity-Specific Files and Folder Structures

After collecting the list of installed apps, LemonLoader examines each app’s contents for patterns unique to Unity projects.

📁 Key Files:

  • libunity.so – Core native library for Unity engine
  • libil2cpp.so – Used in IL2CPP builds (common in VR games)
  • libmain.so – Often present alongside Unity libraries

🗂️ Folder Structures:

  • assets/bin/Data/ – Contains Unity game assets and metadata:
    • globalgamemanagers
    • sharedassets*.assets
    • level* files
    • Managed/Assembly-CSharp.dll (Mono builds)

📦 Other Resources:

  • UnityPlayer.arsc or Unity-specific files in res/ or assets/

These elements are strong indicators that an app is built with Unity.

📜 3. Parsing the AndroidManifest.xml

Every APK includes an AndroidManifest.xml file that defines app metadata. LemonLoader scans it for Unity-related traits:

  • Main Activity: Many Unity games use UnityPlayerActivity
  • Permissions: Certain permissions are commonly requested by Unity apps

While not definitive alone, the manifest provides valuable hints.

🔍 4. Unity Engine Version Detection

Once a Unity game is identified, LemonLoader performs a version check to determine if the game is patchable.

⚙️ How It Works:

  • Reads Unity version from libunity.so, libil2cpp.so, or asset metadata
  • Compares against a supported versions list

This step ensures compatibility with LemonLoader’s patching system.

🛠️ 5. The Patching Workflow After Identification

Once confirmed as a compatible Unity game, LemonLoader proceeds with mod injection:

  1. Extracts APK to a temporary directory
  2. Injects code into libunity.so or libil2cpp.so
  3. Modifies managed assemblies (e.g., Assembly-CSharp.dll) for Mono builds
  4. Repackages the APK with modifications
  5. Resigns the APK (replacing original signature)
  6. Sideloads the patched APK onto the device

This process replaces the original game with the mod-enabled version.

🧩 6. Common Issues & Troubleshooting

Understanding LemonLoader’s detection process helps explain compatibility problems.

🚫 Why Some Unity Games Aren’t Detected:

  • Non-standard Unity builds
  • Heavy file obfuscation
  • Unsupported Unity version

⚠️ Why Some Detected Games Fail to Patch:

  • Anti-tamper mechanisms / DRM
  • Incompatible game updates
  • APK corruption or patching errors

✅ Conclusion

LemonLoader doesn’t guess — it systematically identifies Unity games using a precise set of file structures, native libraries, and manifest metadata. This meticulous detection is what enables safe, reliable modding on platforms like Meta Quest.
