The BS Zelda titles were games released for the SNES Satellaview in Japan only. One of these games was a sort of third quest for the original Legend of Zelda, and featured brand new dungeons, a remixed overworld, and some brand new elements. The game was only broadcasted at certain
times, and would play in real time, and events would occur throughout the broadcast, including voice over from a live narrator! The unique Zelda title is now incredibly hard to find due to its broadcast nature, and only one of the four BS Zelda titles has been officially re-released by Nintendo.
