This is the ones I know of:
Shenmue manga- go into your photo viewer on the main screen, and press the X button to arrange your photos. After about three button presses, you will come to a page with hazy photos. These are people you need to take photos of during the game. After you have filled a page, a gift icon will appear on the album. Highlight this and press A, and you will be able to see Shenmue manga. Each page filled gives you another chapter.
