probably all you actually need to do is make a logo, name it mc360_logo.png and put it in the skins media dir.
but, i edited 'custom1112_GamesHome.xml' and 'Home.xml'to look for mine.
search for mc360_logo in each xml and comment/replace it with your logo name. Place your created logo in xbmc/skin/MC360/media/ and reboot. voila.
awesome skin blackbolt, thanks
