What's the best way to go about embedding a shockwave file in HTML5?

I've been using the following for some time:

<object width="100%" height="100%" classid="clsid:166B1BCA-3F9C-11CF-8075-444553540000" codebase="http://download.adobe.com/pub/shockwave/cabs/director/sw.cab#version=8,5,0,0">
    <param name="src" value="shocwave/file.dcr" />
    <embed src="shocwave/file.dcr" width="100%" height="100%" type="application/x-director" />
</object>

but it appears to have stopped working so I presume something is now outdated?

If you try the codebase link direct then it just displays an error, could this be the issue? http://download.adobe.com/pub/shockwave/cabs/director/sw.cab#version=8,5,0,0

It's proving quite tricky to find documentation on embedding shockwave files though.

How to embed shockwave in html5

The object tag has been modified in HTML5 and this is now the correct way to embed shockwave files:

<object data="shockwave/file.dcr" type="application/x-director" width="100" height="100"></object>
