Würde dann zb für 8 Pixel nach oben dann so aussehen.
Code: 
  #--------------------------------------------------------------------------
  # * Set Window Position and Opacity Level
  #--------------------------------------------------------------------------
  def reset_window
    if $game_temp.in_battle
      self.y = 16
    else
      case $game_system.message_position
      when 0  # up
        self.y = 16 - 8
      when 1  # middle
        self.y = 160 - 8
      when 2  # down
        self.y = 304 - 8
      end
    end
    if $game_system.message_frame == 0
      self.opacity = 255
    else
      self.opacity = 0
    end
    self.back_opacity = 160
  end
