For the first one, take pictures of both "Bay Paintings" using Ashley's DTS. Now you can stack them on top of one another, then turn and move them to get the code.
For the second one, just close the DS about halfway and the top screen should reflect down onto the bottom. Due to differences in the placement of screens, these puzzles work best on the original model DS, though they're still easily solvable on newer models.
