If you wanna play Velocity via browser today, here's what I have for javascript. All you have to do is paste this where you would put the URL (aka ffr.com) in the swf page, and it resizes the game. You may have to manually type javascript: at the very beginning. Also no space in embed.

javascript:void(document.getElementsByTagName('embed')[0].width="1600");void(document.getElementsByTagName( 'embed')[0].height="1050");
