Il2CppDumper GUI for macOS

Native macOS GUI for Il2CppDumper — dump IL2CPP Unity games without external binaries.

Features

• Native C++ dumper — no external binaries, all parsing built-in
• IPA / APK / XAPK / APKS auto-extraction — drag & drop archive to dump
• All binary formats — PE, ELF32/64, Mach-O 32/64, Fat Mach-O, WebAssembly, NSO
• IL2CPP versions 16–31 with automatic version detection
• Full dump output:
  • dump.cs — C# pseudocode (types, methods, fields, properties)
  • script.json — for Ghidra / IDA / Binary Ninja
  • stringliteral.json — all string literals with addresses
  • il2cpp.h — C/C++ header with struct definitions
  • DummyDll/ — dummy .NET assemblies for dnSpy
• Configurable dump options — methods, fields, properties, attributes, offsets
• Force IL2CPP version / Force dump mode
• Manual CodeRegistration / MetadataRegistration input
• Script auto-copy — Ghidra, IDA, Binary Ninja, Hopper scripts
• Drag & Drop — drop files directly onto the start button
• Localization — English / Russian
• Universal binary — Apple Silicon (arm64) + Intel (x86_64)
• macOS 12.0+ compatible

How It Works

1. Core dump (dump.cs) is generated natively in C++ — fast, no dependencies
2. Post-processing (struct generation + dummy DLL) uses a bundled self-contained .NET tool
3. IPA/APK files are automatically extracted, binary and metadata located, then dumped

Usage

1. Open the app
2. Drag & drop an IPA, APK, or XAPK file onto the Start button
   • Or manually select executable, global-metadata.dat, and output directory
3. Press Start — dump.cs and all supporting files will be generated

Building

Requirements

• Xcode 14+
• macOS 12.0+
• Docker (for building the post-process tool)

Build Steps

# Clone
git clone https://github.com/Leeksov/Il2CppDumperGUI.git
cd Il2CppDumperGUI

# Build post-process tool (StructGenerator + DummyDLL)
./build_postprocess.sh

# Open in Xcode and build
open Il2CppDumperGUI.xcodeproj
