🤖 Does LemonLoader Use the Same Mod Loading Mechanism as PC MelonLoader?

A Deep Dive into Shared Foundations and Platform-Specific Engineering

This is one of the most important questions for understanding how LemonLoader functions on Android and how it relates to MelonLoader on PC. The short answer is:
✅ Yes, LemonLoader uses the same fundamental mod loading principles as MelonLoader, but it has been extensively adapted to work within Android’s unique environment.

To really understand this, we need to distinguish between the core mod loading logic and the platform-specific implementations that make it possible.

🧠 The Core Mod Loading Blueprint (Used by Both)

At the heart of both mod loaders is the same core system for loading and running Unity mods:

1. 🧬 Injection into the Game Process

Mechanism: When a Unity game launches, MelonLoader (or LemonLoader) injects itself into the game’s runtime.
Purpose: This allows it to take control before Unity initializes, so it can load mods and hook into the game’s logic.

2. 📁 Scanning for Mods

Mechanism: Looks for .dll files in a Mods folder within the game’s directory.
Purpose: Ensures a standard structure so users can easily drop mods in.

3. 🚀 Loading & Initializing Mods

Mechanism: Loads mod assemblies and finds classes inheriting from MelonMod, initializing them.
Purpose: Allows mods to follow a structured lifecycle (OnApplicationStart, OnUpdate, etc.)

4. 🧩 Harmony Patching

Mechanism: Uses Harmony to patch Unity game functions dynamically.
Purpose: Mods can inject new logic, override behavior, or add new features without changing the game’s source code.

5. 📜 Logging & Debugging

Mechanism: Outputs logs from both the loader and mods, either in a console (PC) or log file (Android).
Purpose: Helps with troubleshooting mod conflicts or development issues.

📱 How LemonLoader Adapts These Principles for Android

Though LemonLoader uses the same mod loading logic, its technical implementation on Android is entirely different due to platform constraints.

🔄 Injection Method (PC vs Android)

🖥️ PC: MelonLoader uses .exe and .dll injection into Windows processes.
📲 Android: LemonLoader must patch native libraries (like libil2cpp.so) for IL2CPP games, which dominate mobile and VR platforms.

🧠 Runtime Differences

PC: Uses full .NET or Mono runtime.
Android: Often lacks a full Mono environment; LemonLoader bundles its own stripped-down Mono or IL2CPP hook system.

🏗️ Architecture Compilation

PC: x86/x64 (Intel/AMD).
Android: ARM (mobile CPUs). Mods and the loader must be recompiled for ARM using cross-platform tools.

🔒 File System & Permissions

PC: Full access to file system.
Android: Restricted by sandboxing and Scoped Storage. LemonLoader navigates these limitations using patching tools and custom installers (like SideQuest for Meta Quest).

📜 Logging

PC: Live console logs.
Android: Logs are written to latest.log in the LemonLoader directory. Viewable via ADB or file managers.

🛠️ Summary: Shared Mechanism, Unique Engineering

Injection	DLL/EXE patching	Binary patching (IL2CPP)
Runtime	.NET / Mono	Mono or IL2CPP on ARM
File Access	Full system	Scoped/Restricted
Logging	Console + File	Log file only
Mod Format	`.dll` compiled for x86/x64	`.dll` compiled for ARM
Mod Compatibility	PC-specific	Must be Android-adapted

🧩 Conclusion

LemonLoader and MelonLoader share the same DNA, but LemonLoader is a custom-built, Android-native mod loader engineered to bring the same modding power to mobile and VR.

It replicates the core MelonLoader architecture—injection, mod scanning, lifecycle management, and Harmony patching—but reimagines it for ARM processors, IL2CPP games, and Android’s stricter environment.

🟢 Bottom line: While the loading mechanism is fundamentally the same, LemonLoader is not a direct port—it’s a platform-specific evolution designed to overcome Android’s unique challenges.
