Even if you’ve been a dedicated Zelda fan since the very first game, there are a couple of Zelda games that you most likely have not played. No, not the CD-i games, but two other Zelda games which were only released in Japan.
The two games, The Legend Of Zelda BS and The Legend Of Zelda: Ancient Stone Tablets, were actually for the BS-X, a satellite-based modem which you could attach to your SNES. With it, you could download games at specific times of the day with the help of a Nintendo radio station.
Interestingly, the games also featured something that doesn’t even appear in present-day Zelda games: live voice acting. If you want to learn more about these “lost” Zelda games, you can read the article about it here.
