Nintendo's Super Game Boy accessory for the Super NES allowed Game Boy games to play on a proper television screen instead of the native hardware's tiny little viewing window.  Games that supported the SGB featured special colorful borders that surrounded the game action to fill out what would otherwise be a dead zone lacking activity.  The VGMuseum (which recently gave us a gallery of incompatible warning screens for the Game Boy) offers up this collection of Super Game Boy borders spanning favorites like Donkey Kong, Wario Land 2, and Mega Man V to international releases and even secret hidden borders from games such as Tetris 2 and Bomberman Quest.  Gaze knowingly at all kinds of detailed, fun artwork that few have seen in the wild.  It's a shame that the Nintendo 3DS Virtual Console service doesn't include support for these borders and other SGB features.  There's some fun stuff locked away in these games.
