Here's page 41 from the manual of The Legend of Zelda for the NES. I've played through the game more than once on a few platforms and I've never seen the cave that's pictured in the top right corner. Has anybody ever come across this cave where you can choose between the sword and the boomerang? Is this in any Japanese release of the game? Does anybody here have the version of Zelda with this in it? What's the story on this one?
I did a bit of searching on the the Internet and on this site and the only mention that I could find of this was in a thread that has something to do with Metroid's Samus being some kind of transvestite.
