If you're a Porting Kit user you probably have noticed that the game icons have a pattern, which is being used by PaulTheTall website for a long time. Well, now that pattern is available in Porting Center, and it's very customizable. Just drop an icon on Porting Center icon field, right-click it and press 'Add Frame'. A new window will be opened and let you customize the icon.
Enjoy it. The icon template was developed by Stuart Ludwig
