Implementing Nesbox in Blog

I wanted to use the game emulator via a nesbox browser in a blog using an external address.

According to the HTML code provided by the developer, the code takes only a portion of the address. Here is the sample code from the developer code to attach the emulator to an html page:

var resizeOwnEmulator = function(width, height)
{
    var emulator = $('#emulator');
    emulator.css('width', width);
    emulator.css('height', height);
}

$(function()
{
    function embed()
    {
        var emulator = $('#emulator');
        if(emulator)
        {
            var flashvars = 
            {
                system : 'sega',
                url : '/roms/Flappy Bird (PD) v1.0.gen'
            };
            var params = {};
            var attributes = {};

            params.allowscriptaccess = 'sameDomain';
            params.allowFullScreen = 'true';
            params.allowFullScreenInteractive = 'true';

            swfobject.embedSWF('flash/Nesbox.swf', 'emulator', '640', '480', '11.2.0', 'flash/expressInstall.swf', flashvars, params, attributes);
        }
    }

    embed();
});

This code is to make available on an internal address, but by using an external server I have put the full address (example: ' link ') and the emulator even shows on the page, but the ROMs do not load correctly, I think because the other files (snes.swf, for example) that emulate the emulator platform are not recognized in the folder I created on the external server.

Does anyone know of this emulator have any idea what it is possible to do to run the emulator from an external address?
