List of North American Game Boy releases, there is another list on List Challenges that has three games that were exclusives to Europe: Beethoven, Monster Max and StarHawk (StarHawk has had a recent release by Limited Run, but it's not an officially licensed Nintendo release.)
I can no longer edit this list, but there are a few mistakes, Blues Brothers Jukebox Adventures and FIFA: Road to World Cup 98 did not get a North American release. Super Breakout is also missing from this list, there is a rare DMG release.
Boggle Plus and Rampart are also missing from the list.
