This method requires to modify game APK. You may need to bypass APK integrity and sig check if you want to use this method

• Build APK with Android Studio
• Decompile app-debug.apk
• Decompile the game
• Copy result libnative.so into the decompiled folder apk
• Search the main activity of the game
• Put this on onCreate function

 const-string v0, "native-lib"
 
 invoke-static {v0}, Ljava/lang/System;->loadLibrary(Ljava/lang/String;)V

• Re-compile and run it
• Wait 10-30 seconds
• Once the dump complete it will auto generate dump.cs in /sdcard/Download

This is useful to get around security. Does not need to modify game APK at all! This is a trick to load our fake libunity.so and load game's renamed lib librealunity.so

Note: Some games does not store the libs in /data/data, you would be unable to do this trick!

• Build APK with Android Studio
• Extract libnative-lib.so from app-debug.apk. Make sure you know what architecture the game is using before proceed
• Rename our lib to libunity.so
• On rooted device/VM, use any file manager app that can access root. Go to /data/data/(package name)/lib
• IMPORTANT! Rename game's libunity.so to librealunity.so
• Put our lib file libunity.so
• Run the game
• Wait 10-30 seconds
• Once the dump complete it will auto generate dump.cs in /sdcard/Download
