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)\n\n* `ForceDump`\n * Force files to be treated as dumped\n\n* `NoRedirectedPointer`\n * Treat pointers in dumped files as unredirected, This option needs to be `true` for files dumped from some devices\n\n## Common errors\n\n#### `ERROR: Metadata file supplied is not valid metadata file.` \n\nMake 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.\n\nIf your file is `libil2cpp.so` and you have a rooted Android phone, you can try my other project [Zygisk-Il2CppDumper](https://github.com/Perfare/Zygisk-Il2CppDumper), it can bypass this protection.\n\n#### `ERROR: Can't use auto mode to process file, try manual mode.`\n\nPlease note that the executable file for the PC platform is `GameAssembly.dll` or `*Assembly.dll`\n\nYou can open a new issue and upload the file, I will try to solve.\n\n#### `ERROR: This file may be protected.`\n\nIl2CppDumper 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 most protections.\n\nIf you have a rooted Android phone, you can try my other project [Zygisk-Il2CppDumper](https://github.com/Perfare/Zygisk-Il2CppDumper), it can bypass almost all protections.\n\n## Credits\n\n- Jumboperson - [Il2CppDumper](https://github.com/Jumboperson/Il2CppDumper)\n" }, { "path": "README.zh-CN.md", "content": "# Il2CppDumper\n\n[![Build status](https://ci.appveyor.com/api/projects/status/anhqw33vcpmp8ofa?svg=true)](https://ci.appveyor.com/project/Perfare/il2cppdumper/branch/master/artifacts)\n\nUnity il2cpp逆向工程\n\n## 功能\n\n* 还原DLL文件（不包含代码），可用于提取`MonoBehaviour`和`MonoScript`\n* 支持ELF, ELF64, Mach-O, PE, NSO和WASM格式\n* 支持Unity 5.3 - 2022.2\n* 生成IDA和Ghidra的脚本，帮助IDA和Ghidra更好的分析il2cpp文件\n* 生成结构体头文件\n* 支持从内存dump的`libil2cpp.so`文件以绕过保护\n* 支持绕过简单的PE保护\n\n## 使用说明\n\n直接运行Il2CppDumper.exe并依次选择il2cpp的可执行文件和global-metadata.dat文件，然后根据提示输入相应信息。\n\n程序运行完成后将在当前运行目录下生成输出文件\n\n### 命令行\n\n```\nIl2CppDumper.exe \n```\n\n### 输出文件\n\n#### DummyDll\n\n文件夹，包含所有还原的DLL文件\n\n使用[dnSpy](https://github.com/0xd4d/dnSpy)，[ILSpy](https://github.com/icsharpcode/ILSpy)或者其他.Net反编译工具即可查看具体信息\n\n可用于提取Unity的`MonoBehaviour`和`MonoScript`，适用于[UtinyRipper](https://github.com/mafaca/UtinyRipper)或者[UABE](https://7daystodie.com/forums/showthread.php?22675-Unity-Assets-Bundle-Extractor)等\n\n#### ida.py\n\n用于IDA\n\n#### ida_with_struct.py\n\n用于IDA, 读取il2cpp.h文件并在IDA中应用结构信息\n\n#### il2cpp.h\n\n包含结构体的头文件\n\n#### ghidra.py\n\n用于Ghidra\n\n#### Il2CppBinaryNinja\n\n用于BinaryNinja\n\n#### ghidra_wasm.py\n\n用于Ghidra, 和[ghidra-wasm-plugin](https://github.com/nneonneo/ghidra-wasm-plugin)一起工作\n\n#### script.json\n\n用于IDA和Ghidra脚本\n\n#### stringliteral.json\n\n包含所有stringLiteral信息\n\n### 关于config.json\n\n* `DumpMethod`，`DumpField`，`DumpProperty`，`DumpAttribute`，`DumpFieldOffset`, `DumpMethodOffset`, `DumpTypeDefIndex`\n * 是否在dump.cs输出相应的内容\n\n* `GenerateDummyDll`，`GenerateScript`\n * 是否生成这些内容\n\n* `DummyDllAddToken`\n * 是否在DummyDll中添加token\n\n* `RequireAnyKey`\n * 在程序结束时是否需要按键退出\n\n* `ForceIl2CppVersion`，`ForceVersion` \n * 当ForceIl2CppVersion为`true`时，程序将根据ForceVersion指定的版本读取il2cpp的可执行文件（Metadata仍然使用header里的版本），在部分低版本的il2cpp中可能会用到（比如安卓20版本下，你可能需要设置ForceVersion为16程序才能正常工作）\n\n* `ForceDump`\n * 强制将文件视为dump文件\n\n* `NoRedirectedPointer`\n * 将dump文件中的指针视为未重定向的, 从某些设备dump出的文件需要设置该项为`true`\n\n## 常见问题\n\n#### `ERROR: Metadata file supplied is not valid metadata file.`\n\nglobal-metadata.dat已被加密。关于解密的问题请去相关破解论坛寻求帮助，请不要在issues提问！\n\n如果你的文件是`libil2cpp.so`并且你拥有一台已root的安卓手机，你可以尝试我的另一个项目[Zygisk-Il2CppDumper](https://github.com/Perfare/Zygisk-Il2CppDumper)，它能够无视global-metadata.dat加密\n\n#### `ERROR: Can't use auto mode to process file, try manual mode.`\n\n请注意PC平台的可执行文件是`GameAssembly.dll`或者`*Assembly.dll`\n\n你可以打开一个新的issue，并上传文件，我会尝试解决\n\n#### `ERROR: This file may be protected.`\n\nIl2CppDumper检测到可执行文件已被保护，使用`GameGuardian`从游戏内存中dump `libil2cpp.so`，然后使用Il2CppDumper载入按提示操作，可绕过大部分保护\n\n如果你拥有一台已root的安卓手机，你可以尝试我的另一个项目[Zygisk-Il2CppDumper](https://github.com/Perfare/Zygisk-Il2CppDumper)，它能够绕过几乎所有保护\n\n## 感谢\n\n- Jumboperson - [Il2CppDumper](https://github.com/Jumboperson/Il2CppDumper)\n" } ]
