Open skin_v3Arcade.php and find:

function row($entry,$gamesplit,$top,$pbest,$links,$rowcol,$rating,$actualtop,$newgame) {
global $ibforums;
return <<<EOF

Below that put:

<script type="text/javascript">
<!--
var newwindow;
function poptastic(url,features)
{
newwindow=window.open(url,'playnew',features);
}
//-->
</script>

Then search for:

{$ibforums->lang['pbest']}: {$pbest}<br />{$entry['v3style_info']}

Below that put:

<!--popup play-->
<a href="javascript:poptastic('arcade.php?$session[sessionurl]do=playfull&amp;gameid={$entry['gid']}', 'height={$entry['gheight']},width={$entry['gwidth']},left=200,top=100,resizable=yes,scrollbars=yes,toolbar=yes,status=yes');">{$ibforums->lang['gamebox_playpopup']}</a><br />

That should work
