Keeping player off-center of screen?

[CapnMuffin]

I was wondering how I could edit the script to make it so the player was kept somewhere else besides the center of the screen?
Namely, the bottom of the screen, centered... so that when they moved up or down they would stay on the bottom.

 

[EOG]

Here's script just put it before Main:

# Hero position on map by EOG
# no credit need
class Game_Player < Game_Character
  def center(x, y)
    @disp_x = 0    #how much left/up hero must be?
    @disp_y = 600  #how much up/down hero must be?
    max_x = ($game_map.width - 20) * 128
    max_y = ($game_map.height - 15) * 128
    $game_map.display_x = [0, [x * 128 - (CENTER_X+@disp_x), max_x].min].max
    $game_map.display_y = [0, [y * 128 - (CENTER_Y+@disp_y), max_y].min].max
  end
  def update
    # Remember whether or not moving in local variables
    last_moving = moving?
    # If moving, event running, move route forcing, and message window
    # display are all not occurring
    unless moving? or $game_system.map_interpreter.running? or
           @move_route_forcing or $game_temp.message_window_showing
      # Move player in the direction the directional button is being pressed
      case Input.dir4
      when 2
        move_down
      when 4
        move_left
      when 6
        move_right
      when 8
        move_up
      end
    end
    # Remember coordinates in local variables
    last_real_x = @real_x
    last_real_y = @real_y
    super
    if @real_y > last_real_y and @real_y - $game_map.display_y > (CENTER_Y+@disp_y)
      $game_map.scroll_down(@real_y - last_real_y)
    end
    if @real_x < last_real_x and @real_x - $game_map.display_x < (CENTER_X+@disp_x)
      $game_map.scroll_left(last_real_x - @real_x)
    end
    if @real_x > last_real_x and @real_x - $game_map.display_x > (CENTER_X+@disp_x)
      $game_map.scroll_right(@real_x - last_real_x)
    end
    if @real_y < last_real_y and @real_y - $game_map.display_y < (CENTER_Y+@disp_y)
      $game_map.scroll_up(last_real_y - @real_y)
    end
    # If not moving
    unless moving?
      # If player was moving last time
      if last_moving
        # Event determinant is via touch of same position event
        result = check_event_trigger_here([1,2])
        # If event which started does not exist
        if result == false
          # Disregard if debug mode is ON and ctrl key was pressed
          unless $DEBUG and Input.press?(Input::CTRL)
            # Encounter countdown
            if @encounter_count > 0
              @encounter_count -= 1
            end
          end
        end
      end
      # If C button was pressed
      if Input.trigger?(Input::C)
        # Same position and front event determinant
        check_event_trigger_here([0])
        check_event_trigger_there([0,1,2])
      end
    end
  end
