📋 Requirements

• Megabonk (Steam version)
• BepInEx 6.0.0+ (Unity IL2CPP version)

Installation

Automatic (Recommended)

• Install r2modman or Mod Manager
• Search for RarityForce in the mod manager
• Click "Install"
• Launch the game through the mod manager

Manual

• Download and install BepInEx 6.0.0+ IL2CPP for your game
• Run the game once to generate BepInEx folders
• Download the latest release or GitHub Releases
• Extract RarityForce.dll into BepInEx/plugins/ folder
• Launch the game

Building from Source

• Clone the repository:

git clone

cd rarity_force

• Copy required DLLs from your Megabonk installation to libs/ folder:
• BepInEx/core/BepInEx.Core.dll
• BepInEx/core/BepInEx.Unity.IL2CPP.dll
• BepInEx/core/0Harmony.dll
• BepInEx/core/Il2CppInterop.Runtime.dll
• BepInEx/interop/UnityEngine.dll
• BepInEx/interop/UnityEngine.CoreModule.dll
• BepInEx/interop/Assembly-CSharp.dll
• BepInEx/interop/Il2Cppmscorlib.dll

• Build the project:

dotnet build -c Release

Or use the build script:

• Windows: build.bat
• Linux/Mac:./build.sh

• The compiled DLL will be in bin/Release/net6.0/RarityForce.dll

How It Works

The mod uses Harmony to patch the game's GetItemRarity method. When forced rarity is enabled (F1), it overrides the game's random rarity selection with your chosen rarity.

Technical Details:

• Patches Assets.Scripts.Inventory__Items__Pickups.Rarity.GetItemRarity()
• Uses reflection to access Unity's Input system for IL2CPP compatibility
• Asynchronous sound playback via Task.Run() to prevent game freezing
