My b2evolution Version: 3.3.0rc1

I want to post swf flash games on the blog for people to play. I have a couple of flash player plugins installed, but none of them work for playing flash games. One site I can embed games from recommends using this code:

<center><object width="350" height="250">
<param name="movie" value="http://kidsgamesblog.com/online/arcade/47.swf">
<embed src="http://kidsgamesblog.com/online/arcade/47.swf" width="525" height="375">
</embed>
</object>

When I paste the code into the blog post it says that it has invalid content. What happens if I shut off the validation rules and post it anyway since it appears to work in the preview?

Is there a plugin or anything that can run a swf flash game? If not I would like to request a plugin that would allow this.

thanks,
Robert
