Override Save Location (VX Ace)

#============================================================================
# Override Save Location
# v1.0 by Shaz
#----------------------------------------------------------------------------
# This script allows your game to put save files into the player's
# AppData folder, in a subfolder with the same name as the game.
#
# So, if your game is called Dragon Conquerer, save files will go into
# User/AppData/Roaming/Dragon Conquerer
#
# This means several people can use the same PC under their own profiles,
# and have their own save files that can't be accidentally overwritten by
# others; players can uninstall, reinstall and overwrite your game without
# losing their save files; gets around file access issues if the game has
# been installed into a folder with additional Windows security.
#----------------------------------------------------------------------------
# To Install:
# Copy and paste into a new script slot in Materials.  This script aliases
# existing methods, so can go below all other custom scripts.
#----------------------------------------------------------------------------
# To Use:
# No steps necessary - it just works.
#----------------------------------------------------------------------------
# Terms:
# Use in free or commercial games
