Quoted from bobukcat:
They're discussed and detailed in the thread I posted the link to above. Short version, shoot everything a ridiculous number of times then manage to hit all the rescue targets (loop no longer spots them) then a all-in-one loop and shot to the castle doors (will be open). I've never really even gotten close, especially since the required shots to the crystal ball are both prone to drain if missed and almost always leads to a CB mode that makes the task of hitting all those aforementioned shots even harder. Oh yeah, the right orbits don't count if you hit them during a ball-save auto-launch either. Piece of cake!
wow that's too hard, I'm going to need to up my game.
