nope it puts u bak on the save files and u start from where u last saved(4 me just b4 beatin the boss)
That's why you just save outside the boss room and then leave... go finish side quests, go back and get all of the chests from previous temples.
Man I was stupid the first time i beat it. I forgot to save and so after beating Ganondorf, i started my file again and i had just finished the Twilight Realm.
At least the second time I did Hyrule Castle I got everything, including the stupid other small key that i missed the first time. It unlocks the best room in the game. The room right beside the Boss room contains way too many rupees and other goodies (i mean seriously, water bombs and pumpkin seeds? How will that help me beat Ganon??)
The rupees were nice though, especially that beautiful silver one (200 rupees heck yes!)
yea i found that 1s time outta curiosity...i got 1 key then went the other way and i fought a green moblin(beautiful joust battle earlier on)
Both jousts were fun... totally knocked his as s into the abyss. TAKE THAT GREEN FAT GUY!!! take my kid friends again, and then see what happens...
