No source files have been leaked ever. Other then reverse engineering the server files from client side which has seen to work for Runescape for example, I doubt vendetta would be able to make a grand server.
How would they even make one?
I'm confused about how vendettagn would even make a grand fantasia private server? People keep referring to the ignit games version as a 'private' server when they own a license to the game.
Does vendetta currently own licenses to the games they host already or?
