Damn,
loz.zeldalegends.net is so cool. For years now I've been wanting to read a comparison of the Japanese and US versions of the manuals and
here it is. Although it shows the Japanese and US versions of the story for at least The Legend of Zelda are pretty much the same it shows some interesting insights. Also the enemy names and descriptions comparison is really cool.
The webmaster also plans on making a Japanese vs. US comparison for the Adventures of Link and A Link to the Past manuals. I think I'm most excited about reading the comparison for the Adventures of Link manuals. Of all the games I've always felt that there was a lot of stuff missing from the story and things that just didn't make sense like the whole sleeping Princess Zelda thing. I feel this was probably due to a really bad translation so hopefully the Japanese version translation will shed some light on it.
