Hi, I'm trying to decode the GCWelcome message from the Game Coordinator. Most of it already works, but there are two fields I can't find any documentation for. After inspecting the GC response with NetHook2 Analyzer, the fields game_data and game_data2 remain unclear. I haven't been able to decode them or find any information about their structure. Does anyone know how these fields are encoded and what data they contain?
