358/2 DAYS MASTERObtain all trophies.
This is basically a Platinum Trophy but instead they just ranked it as Gold considering the Trophies for this portion of the Kingdom Hearts 1.5 HD Collection is
really easy. You need to achieve all of the other trophies for this game in order for this to unlock. You do this by watching all the videos (or skipping through the list of them), and reading all of Roxas' Diary entries and Secret Reports.
WARNING: For some reason this doesn't unlock for some gamers such as myself. I don't know why, it's probably just a glitch but it has been reported by others, as well.
I found this solution thanks to Devil_Spooky:

1 - Check everything again, NOT the videos, the character Bios, Roxas diary, secret diary.
2 - Watch the last scene again, make sure it finish until it goes back to the menu.
3 - Back out of the game, DON'T EXIT TO THE XMB.
4 - You should get the trophy and the Theme for the game.
