Game Client Plugin to fake packet request to Server

Ok so this a bit hard to explain but here is the jist of it. Theres a game called Ultima Online. It's free client to install but you have to pay a monthly subscription. Fortunately, there is an emulator called RunUO (its open source) that allows players to run their own servers and play free that is coded in C# and C++ or something? Idk here is link: [login to view URL] - All I know is you run the .exe and every script you write is a C# file. Now there is a script someone in the community made you simply just drop in your runuo server directory that contains all the c# files that is a c# obviously open source since you have the code to install. What it does is sends a packet of some sort to the Program called Razor which is what is used to connect to these RunUO servers ([login to view URL]) to see if there is an option checked to "Negotiate Features with server". Ok so I have a custom client that you can , that just like runuo ..you code c# files to inject straight into the client ( i have the library for it made by developer :P its sort of a hacked client also have plugins that use the library already coded you can use for reference for certain things actions if you'd like). So what I need is a plugin coded for my custom client that sends that packet back that razor contains or whatever in that negotiate features with server tick box to pretend like I'm using razor when Im not. ; Ok so you'll gain experience if you know these languages, and ultimately have a blast writing cheats for a FUN ASS outdated multilayer pvp style game that relatively easy to cheat in if you can code in c#. Trust me your going to get addicted and divorced.
