I heard there was a video you can unlock at the end if you finish Jiminy's journal in KH2, but only on Normal Mode. Well, I'm on Proud Mode, way into the game. Can I still get the video to appear at the end?

Another question: I was reading that Mickey has a limit break. Well, I am at the part where you meet Mickey in Hollow Bastion. Do I need his limit break to complete Jiminy's journal? If so, can I still get it?
