Kingdom Hearts DS unlockables

I've beaten the game but there is no "Soul of Sora" or "Return of the King" for me to buy in the Moogle Shop. How do I get them, and where exactly will they be located in the shop?

To unlock Return of the King, you need to complete all missions.
For Soul of Sora, you need to complete everything in the game.

To be more specific, you need to beat the game and complete the now-unlocked extra missions in the Holo-Mission menu to unlock Return of the King in the Moogle Shop.To unlock Soul of Sora, you must complete all objectives in all missions to Gold level.

ok thanks that makes alot more sense because all the gaming websites weren't very specific. It just said to beat the game.
