Some of your facts arent straight...
Zelda doesnt turn into a guy. That's Sheik, Link's guide. Zelda needed to hide from Ganondorf, else she would be captive. So she changes her outfit to hide her appearence. One of the surprising twists of Orcarina of Time. They meant for the surprise to be that Sheik was Zelda, but for most, it was that it wasn't a dude. There are many jokes about it.
Also, I dunno if I got the question wrong or right, but in Brawl, I answered 15 for the second question, and the screen went black. You may have a linking error. Fix it up, and this game will kick some major ass.
