Unity il2cpp reverse engineer
- Complete DLL restore (except code), can be used to extract
MonoBehaviour
andMonoScript
- Supports ELF, ELF64, Mach-O, PE and NSO format
- Supports Unity 5.3 - 2020
- Supports generate IDA and Ghidra scripts to help IDA and Ghidra better analyze il2cpp files
- Supports Android memory dumped
libil2cpp.so
file to bypass 99% protection
Only support Command-line
The program will then generate all the output files in current working directory
Il2CppDumper.exe <executable-file> <global-metadata>
Folder, containing all restored dll files
Use dnSpy, ILSpy or other .Net decompiler tools to view
Can be used to extract Unity MonoBehaviour
and MonoScript
, for UtinyRipper, UABE
For IDA
For IDA, read il2cpp.h file and apply structure information in IDA
structure information header file
For Ghidra
For ida.py and ghidra.py
Contains all stringLiteral information
All the configuration options are located in config.json
Available options:
-
DumpMethod
,DumpField
,DumpProperty

,DumpTypeDefIndex
- Whether to output these information to dump.cs
-
DummyDll
- Whether to generate dummy DLLs
-
MakeFunction
- Whether to add the MakeFunction code in script.json
-
ForceIl2CppVersion
,ForceVersion
- If
ForceIl2CppVersion
istrue
, the program will use the version number specified inForceVersion
to choose parser for il2cpp binaries (does not affect the choice of metadata parser). This may be useful on some older il2cpp version (e.g. the program may need to use v16 parser on il2cpp v20 (Android) binaries in order to work properly)
- If
Make sure you choose the correct file. Sometimes games may obfuscate this file for content protection purposes and so on. Deobfuscating of such files is beyond the scope of this program, so please DO NOT file an issue regarding to deobfuscating.
Make sure the executable is not protected, you can open a new issue and upload the file, I will try to solve.
Il2CppDumper detected that the executable file has been protected, use GameGuardian
to dump libil2cpp.so
from the game memory, then use Il2CppDumper to load and follow the prompts, can bypass 99% protection
