Coded How to unlock the secret ending?

I've remained unspoiled of this game other than the odd trailer, but dont know much of the overall plot and secret ending, and wish to keep it that way until I play. However I'd like to unlock the secret ending myself, so would someone be kind enough to share that information and nothing else for me and others who wish to be unspoiled? Thanks!

 

Well you're going to have to complete the game, so you're going to be spoiled either way.

Collect all Trophies, play in critical or proud (i believe) or you can simply just watch the Secret Ending if you like on YT.

 

Really, you should be playing KH at proud mode anyway. It's insanely easy otherwise. (At proud, it's only slightly easy.)

 

Re:coded is a little different from the others.
In it, you can change the difficulty any time you have acess to the Status Matrix, which is on the main menu since early on.
To get the secret ending to show up in the Theater, you gotta get 20 of the 30 Trophies in-game, the Trophies are:

Spoiler

Rare Prize - 100% Rare Prize boxes (the metal starred boxes)
Drop Get - 100% enemy drops (Get drops from every enemy on each of the 4 difficulties)
System Area - Clear all System areas
Slot Set - Fill in every slot in the System Matrix
Cheat - Gain access to all 5 Cheats in the System Matrix
Collector - Obtain at least 70% of all Abilities, Chips, Cheats, Weapons and Items
Avatar Get - Get 50% of all Avatar parts (Need to do wireless link, thankfully, like in TWEWY, random signals will act as "aliens")
Avatar Area - Clear the 100 floors of the special Avatar Dungeon(1 person found = 1 Floor)
Ice Titan - Defeat the Ice Titan at Olympus Colosseum (30 Layer Trial, only possible after clearing story version, then re-doing it, choosing and completing the 15 layer trial).

Technical - Clear every world with Sora at below Lv.15
W1 Sprinter - Clear World 1 under 5 minutes
W2 Sprinter - Clear World 2 under 15 minutes

W6 Sprinter - Clear World 6 under 15 minutes
W7 Sprinter - Clear World 7 under 30 minutes
W8 Sprinter - Clear World 8 under 10 minutes

 

Alright, thanks for the help :D

 

If you can change the difficulty at any time, what does that mean for the Proud and Critical trophies? Can't you just switch difficulties before the final boss, or before the end of a level?
