## What it is
Il2CppDumper is a C# command-line tool that extracts type, method, and string information from Unity IL2CPP binaries and their global-metadata.dat files. It restores dummy DLLs and generates analysis scripts for IDA, Ghidra, and Binary Ninja to aid reverse engineering of Unity games.

## Use cases
- dump il2cpp metadata from a unity game
- restore dummy dlls from libil2cpp.so and global-metadata.dat
- generate ida or ghidra scripts for il2cpp analysis
- extract monobehaviour and monoscript info from a unity build
- reverse engineer an android unity game
- analyze il2cpp wasm or nso binaries

## When to choose
- you need to reverse engineer a Unity IL2CPP game's code structure
- you want symbol and structure information loaded into IDA, Ghidra, or Binary Ninja
- you need to inspect MonoBehaviour/MonoScript definitions from a compiled Unity app

## When to avoid
- you need to decompile actual native code logic - it only restores metadata, not code
- you are working with Mono (non-IL2CPP) Unity builds
- you want a GUI tool - it is command-line driven

## Facets
