I have just finished writing a boss guide for The Legend of Zelda. This guide goes into boss strategies and descriptions. So, if you are having any problems defeating one of the bosses from the original Legend of Zelda game then I highly suggest taking a look at this guide.
Right now, it is my goal to finish all guides for The Legend of Zelda and to work my way up through the games. So stay tuned as more guides should be added shortly.
