Better Run It in the browser?
Anyway, here's the HTML code... Copy and Paste to Notepad, Save the file as: GameLoader.html file in the same folder as the swf file, and Rename the swf as : RotMG.swf
Code:
<html lang="en"><meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<meta http-equiv="CACHE-CONTROL" content="NO-CACHE">
<meta http-equiv="PRAGMA" content="NO-CACHE">
<meta http-equiv="Expires" content="-1">
<title>Realm of the Mad God</title>
<body BGCOLOR="#000000" oncontextmenu="javascript:return false">
<center>
<embed src="RotMG.swf" bgcolor="#000000"
width="800" height="600" name="GameClient" align="middle"
quality="low"
wmode="direct"
menu="true"
allowScriptAccess="always"
type="application/x-shockwave-flash"
pluginspage="https://www.adobe.com/go/getflashplayer">
</embed>
</center>
</body>
</html>
