ProtoDumper

This program dumps Protocol Buffer definitions from game assemblies, they are used for own made servers or packet analyzing.

It requires unobfuscated assemblies as I still didn't implement obfuscated assembly support.

Usage

Build it using Visual Studio 2022
Open the .exe file and choose the assembly with proto definitions (Assembly-CSharp.dll), alternatively use command line
