Lost your game manual? Find below a complete scan of the Metroid Prime Trilogy instruction booklet. Note that this manual belongs to a PAL copy of the game, so where it reads on page 6 that only other PAL owners of the game can receive Friend Vouchers, the same applies for NTSC - you can only send vouchers to friends who own the same regional version of the game as your copy.
