In your XAMPP htdocs folder, create an index.html file that embeds your modified .swf.
<!DOCTYPE html>
<html>
<head>
<title>My AQW Private Server</title>
</head>
<body>
<embed src="my_custom_client.swf" width="960" height="550">
</body>
</html>
Ensure MongoDB is running.
Create the database:
mongo
use aqw
exit
If parameters don't work, you must hex-edit the SWF.
