Picross 2

From Wikipedia: Picross 2 (ピクロス2) for the Game Boy is a Japan-exclusive collection of nonogram logic puzzles involving a grid with numbers for every row and column, which refer to the amount of marked squares within the grid, and the sequel to this game. Unlike this game, Picross 2 contains a world map. Also, the pictures are larger, consisting of four 15x15 picross boards.
