Open Rom (nes) file in browser in ASP.Net MVC

I want to use EMULATORJS to open my rom game to my Browser using ASP.NET MVC. I made folder and added my nes file using EmulatorJs. I have no idea I could not open my nes file in this EmulatorJs.

Anyone know how to open nes file in my browser?

<div style="width:640px;height:480px;max-width:100%">
    <div id="game"></div>
</div>
<script type="text/javascript">
  EJS_player = '#game';
  EJS_biosUrl = ''; // Url to Famicom Disk System bios
  EJS_gameUrl = '~/Swf/new-mario-bros.nes'; // Url to Game rom
  EJS_gameID = 1; // ID in your website, required for netplay.
  EJS_core = 'nes';
  EJS_lightgun = false; // Lightgun
</script>
