How to Unlock all the SSE clips-
I just figured it out, and thought I'd post it for all you that didn't know.
First, play the SSE all the way through. Remember which princess you saved from Petey at the very beginning. And Remember if you used Metaknight to beat Lucario at the Glacial peak (or did you pick Lucario). Then start all over. I just chose easy and ran through as fast as possible. On your second time through, all you have to do is save the other princess from Petey. When you get to the top of Glacial peak, use the character you didn't use the first time. I went through about as fast as I could and it took an hour and 45 minutes.
I hope this helps. And if this has already peen posted... oops. I didn't see it when I searched.
