To reconstruct the code, you need both the executable binary and the metadata file to work in harmony. Why is it "Encrypted"?
There are two main ways to handle a protected file: and Memory Dumping . Method 1: The Memory Dump (Easiest)
If you’ve ever dipped your toes into the world of Unity game modding or reverse engineering, you’ve likely hit a brick wall known as global-metadata.dat . This file is the backbone of Unity’s (Intermediate Language To C++) scripting backend, and without decrypting or "dumping" it, the game’s code remains an unreadable mess of machine instructions. decrypt globalmetadatadat
Once you have a decrypted file (or if the file wasn't encrypted to begin with): Run Il2CppDumper.exe . Select the executable file ( .so or .dll ). Select your global-metadata.dat .
For viewing the "dummy" DLLs created after decryption. To reconstruct the code, you need both the
Even if the file is encrypted on your hard drive, the game must decrypt it in the device's RAM to run. Launch the game on an emulator or rooted device.
Often, "encryption" is just the developer changing the first few bytes of the file to throw off automated tools. Open your global-metadata.dat in a Hex Editor. Method 1: The Memory Dump (Easiest) If you’ve
Advanced modders use a disassembler (like IDA Pro) on the libil2cpp.so file to find the MetadataCache::Initialize function. This function contains the logic the game uses to "unlock" the metadata. Method 3: Using Il2CppDumper
Check the first 4 bytes. If they aren't AF 1B B1 FA , the tool will fail.
