Gemnet: a Rumble Fighter/Gem Fighter server emulator

Gemnet reconstructs a server for Rumble Fighter/Gem Fighter, with handlers for inventory, avatars, lobby, chat and P2P gameplay. Its C# packet processor parses message headers, handles optional decryption and dispatches packet types and actions to game-specific handlers.
