Hmm, I have actually only ever played BBS on the PSP, so I'm assuming it's probably different on the PS3. Wish I could help! Hopefully someone on here will know what to do.
Hey! To unlock final episode, you need to get all of Xehanort's Reports then finish the game again with any of the three characters. The only one that's not in a chest is the one on Mirrage Arena and you must play as Terra, not sure what round though...
And the secret episode can't be unlocked on begginer mode and on standard you must have 100% with all characters. It will unlock if you have beat the game on proud or critical!
