Making a plugin to replace the Title?

[EmilyAnnCoons 7]

Okay, so, I need either help programming it, or I need it programmed (I kinda wanna learn, so the first is preferred, I guess?)

 

Basically, I want to create a plugin that replaces the Title screen. Rather, I want it to edit the screen so it adds a fourth option. I want to have the options: "New Game", "New Game With Tutorial", "Load Game", and "Options" on the menu. It'd basically be the same as the current title screen but with the tutorial thing added. What it would do would be to load up the game by going to a specific set of X and Y coordinates on a specific map instead of loading the default map and set up. Here's what I have so far, but none of the parameters show up in the plugin manager, so I'm assuming it isn't working:

 

 

(function() {

var parameters = PluginManager.parameters('Scene_NewTitle');
var MapID = Number(parameters['Tutorial Map ID'] || 1);
var x = Number(parameters['X Value'] || 0);
var y = Number(parameters['Y Value'] || 0);

var Scene_NewTitle = Scene_Title.prototype.createCommandWindow;
Scene_Title.prototype.createCommandWindow = function() {
    this._commandWindow = new Window_TitleCommand();
    this._commandWindow.setHandler('newGame',  this.commandNewGame.bind(this));
    this._commandWindow.setHandler('newGame2', this.commandNewGame2.bind(this));
    this._commandWindow.setHandler('continue', this.commandContinue.bind(this));
    this._commandWindow.setHandler('options',  this.commandOptions.bind(this));
    this.addWindow(this._commandWindow);
};

Scene_Title.prototype.commandNewGame2 = function() {
    DataManager.setupNewGame();
    $gamePlayer.reserveTransfer(MapID, x, y);
    this._commandWindow.close();
    this.fadeOutAll();
    SceneManager.goto(Scene_Map);
};

function Scene_NewTitle() {
    this.initialize.apply(this, arguments);
}

Scene_NewTitle.prototype = Object.create(Scene_Base.prototype);
Scene_NewTitle.prototype.constructor = Scene_NewTitle;
}) ();
