This save puts you in Kakariko Village with all the letters in the book. Just go in the house, downstairs, through a couple cutscenes then warp the cannon out of there.
Remember, don't save in the room. :)

If you did save in the cannon room DONT RESTART YOUR GAME!!! You can get by this glitch. Slowly walk forward from the cannon towards the sreps. Watch the A button. It will eventually say speak. Press A and the invisible person will leave. Now you can continue with the game. It may take more than one try. I got it on my first.
