#=============================================
# This script allows you to have as many save files as necessary for your game.
# Simply find GAME_SAVES and change the value to your liking.
#
# This overwrites the Scene_File class and the Window_SaveFile class.
# This will overwrite any other custom save menus.
#
# You will need your own cursor image for this to work properly!
# It can be anything but keep it small.
# And remember to name it "cursor.png", OK?
#
# If there are any suggestions to make this script cleaner and more efficient, please let me know.
#
# If there are any errors, let me know that too, OK!
#
#  Please credit me for this.

# You only have to edit this and the rest handles itself.
