Project Visitor

Im looking for some direction here , Im trying to figure out if there is a way to pull server files / create server files from a client, it is a it is a webpage based game ( i beleive) like runescape , its called Project Visitor. I notice that most of the server files here were ( leaked) . Is this a feasable project ? Any correct direction would be appreciated.

Clear it up please.

What im trying to do is create a pserver from a client

I don't think there is any of that looking that the game you are talking about is not so well-known to people.
But i will try to help.
