The game was originally only broadcast in Japanese, but you can now download language patches in English, French and German here and try the game out through an emulator for yourself. But getting a working version of the game together took more than just translation. Originally, The Legend of Zelda: Ancient Stone Tablets was broadcast in four one-hour chunks. That's right, the game was broadcast at a specific time once a week for four weeks, and you could only access that particular part of the game at that time.
Making things even more tricky is the fact that each game's broadcast was accompanied by streamed audio that contained voice acting and orchestrated music -- getting that entire four-hour audio broadcast together and in sync was one of the biggest challenges in offering a complete version of this game. Semi-complete ROMS have been offered for a long time, but this seems like the closest we've gotten to a comprehensive vision of the game.
You can download the game now, and this site has way more details about this Nintendo oddity. Anyone who loved Link to the Past (and that's a lot of people, given the game's status as one of the best of the entire series) should give this a shot.
