Tips

Detect User Agent

To detect if the user agent is Nintendo 3DS Browser :

<script type="text/javascript">
     window.onload=function() 
     {
         if (navigator.userAgent.indexOf('Nintendo 3DS') == -1) //If the UserAgent is not "Nintendo 3DS"
         {
               location.replace('http://www.3dbrew.org'); //Redirect to an other page
         }
     }
</script>

Screen Resolution

The up screen resolution is 400×240. However, the viewable area in the browser is only 400×220.

The touch screen resolution is 320×240. However, the viewable area in the browser is only 320×212.

You can have a page span both screens. However, the browser will behave as if the bottom screen is the only active screen and the top screen is scrolled off. This is important when computing CSS coordinates. Items positioned from "bottom" will be positioned based on 220px and not the full 432px of both screens.

Using Both Screens

Here's how your webpage can span both screens:

Ensure that your page takes up exactly 320x432 pixels.
Add the following JavaScript just before the </body> tag:

<script>document.body.scrollTop = 220;</script>

Generally the easiest way to accomplish the correct layout is to create HTML elements that "contain" the top and bottom screens. Here's an example:

<html>
  <head>
    <meta name="viewport" content="width=320">
    <style>
      body { margin: 0px; }
      #topscreen { width: 320px; height: 220px; overflow: hidden; }
      #bottomscreen { width: 320px; height: 212px; overflow: hidden; }
    </style>
  </head>
  <body>
    <div id="topscreen">Top Screen</div>
    <div id="bottomscreen">Bottom Screen</div>
  </body>
</html>

This scheme allows the page to be easily manipulated through JavaScript.
