Hi here. So I've completed Sora's story on the:Chain of Memories and started a gamw with Riku.

I don't know how I did that but I save my new game on top of my Sora save file. My question is, after I complete Ricky's story, if I start a new one with Sora, will I be able to get the cards that are unlocked by beating Riku's story or do I have to finish the game again?
