Play it again!
Hey, I really have no idea where you can find Zelda Savestates, but I would not use them even if I'd know!
I can give you an advice: play it again, and again and again...

Well, the BEST thing to do is to play it several times, to better appreciate the essence of this wonderful game. If you get sick doing the same things over and over, you can simply get adult, get Epona and go around, go around and around (does this remind me of someone?

)
Well, I just wanted to make you enjoy at all this game...
Actually, I played it several (many) times, and I'm still enjoying it!!
See ya and have fun!
