🍋 LemonLoader — Advanced Modding Framework for Android [Unity & VR Games]

LemonLoader Banner


Table of Contents


Overview

LemonLoader is a cutting-edge open-source mod loader designed to unlock deep customization for Unity Engine games on Android devices and standalone VR platforms like the Meta Quest. Acting as a mobile counterpart to the acclaimed MelonLoader for PC, LemonLoader empowers users and developers to inject and execute custom C# code mods, going far beyond simple asset replacements to alter core gameplay mechanics, add new features, and fix bugs.

This tool bridges the gap between PC and mobile modding ecosystems, bringing the power of universal Unity modding to your fingertips — transforming how you experience your favorite Android and VR games.


Key Features

  • Robust Code Modding
    Inject and execute complex C# code mods that change game logic, mechanics, and UI.

  • Mono & IL2CPP Support
    Seamlessly supports Unity’s two primary scripting backends, including reverse-engineering of IL2CPP binaries for deep mod integration.

  • Binary Patching & Injection
    Patches game APKs on Android to load the mod loader environment before the game launches.

  • External Mod & Plugin Loading
    Supports loading third-party .dll mods and plugins stored in designated folders.

  • Developer-Friendly Debugging Tools
    Built-in logging, launch arguments, and runtime debugging aid mod developers.

  • Universal Unity Android & VR Compatibility
    Works on Android phones, tablets, and standalone VR headsets like Meta Quest running Unity games.

  • User-Friendly Installer
    Simplifies the patching and mod installation process with an intuitive interface.

  • Open Source & Community Driven
    Transparent development encourages contributions, rapid improvement, and trust.


How LemonLoader Works

LemonLoader functions by patching the target Unity game's APK, injecting a bootstrapping routine that initializes its runtime environment before the original game code executes. This enables:

  • Loading and executing custom .NET assemblies (mods/plugins).
  • Interacting with internal game functions and data structures using C#.
  • Supporting both Mono (easier modding) and IL2CPP (complex native binaries) through advanced reverse-engineering tools like Il2CppAssemblyUnhollower and Cpp2IL.

This modular, injection-based design ensures high compatibility and modding flexibility across a broad range of Unity Android titles.
