# DO TOUCH THE VALUE BELOW! If you change the required version to a lower
# value your script WILL malfunction, because older DREAM version don't have
# all the methods and functions required by this script.
Required_DREAM_Version = 4.1
#
#
# Special Thanks to:
#
# - the makers of the XVI32 Hex Editor
# (without it, I couldn't have tested this script)
#
#
# Compatibility:
#
# 98% compatible with SDK 1.x. 90% compatible with SDK 2.x. 99% compatible
# with everything else. WILL corrupt your old savegames. Can cause
# incompatibility issues with custom save screens. NEEDS DREAM of the
# provided version or higher. Files will be saved into dream4 format with
# .dream4 extension. Cannot decode dream2 and dream3 files where extra data
# was added, but normal dream2 and dream3 files can be decoded.
#
#
# Features:
#
# - uses the Double Random Encryption Algorythm Module (DREAM) to encrypt
# important save data every time it is saved
# - makes it harder to hack saved files (even experienced hackers will have a
# hard time hacking important data from save files encrypted with DREAM)
# - great for RMXP MMORPGs as alternative for saving data on the server
#
# new in v2.0:
# - uses DREAM v3.0 which is far more powerful than DREAM v2.0, because the
# .dream3 format is a format in which ALL the saved data is encrypted
# - your savefiles will be saved into files with .dream3 extension
#
# new in v3.0:
# - uses the even more powerful DREAM v4.0
# - faster, better, safer:
# -> new, much faster algorithm which's speed doesn't depend on the chosen
# encryption pattern anymore
# -> re-coded to avoid the built-in RGSS bug with conditioning
# -> new additional encryption of encrypted data
# - your savefiles will be saved now into files with .dream4 extension
# - displays "File corrupted!" instead of crashing when files are corrupted
# - can decode dream2 and dream3 format
#
# new in v3.0b:
# - now uses DREAM v4.1
# - direct implementation into DREAM
# - now beta
#
#
# Configuration:
#
# Open the Scene_Title script and find these lines or similar:
#
# for i in 0..3
# if FileTest.exist?("Save#{i+1}.rxdata")
# @continue_enabled = true
# end
# end
#
# Change this line:
# if FileTest.exist?("Save#{i+1}.rxdata")
# into this one:
# if FileTest.exist?("#{SAVE_NAME}#{i+1}.dream4")
#
# Change SAVE_NAME to the name your savefiles should have. i.e. Making it
# "The Last_Elf" will make your savefiles look like "The Last_Elf.dream4".
#
# Find the part that needs to be configured and add additional data if you
# are using additional savedata. Include all additional data AS STRINGS in
# the array EXTRA_DATA. Example:
#
# EXTRA_DATA = ['$game_weapons', '$game_armors', '$game_items']
#
#
# IMPORTANT NOTES:
#
# This script will encrypt all save data and render them 100% unusable by any
# earlier version of your game that DOES NOT have this script. If you are
# using save-game update of earlier versions, this script will make further
# updates of old savegames IMPOSSIBLE, because they can't be loaded at all.
# Please use a DREAM save file converter to convert usual save files into a
# DREAM readable format. Note that this version of this script can also READ
# save files encrypted in dream2 and dream3 format only if their extension is
# being changed to .dream4 and their names are changed like configured below.
# Note that any extra data from dream2 and dream3 files will not be read.
# This script will save any files into .dream4 format. Changing this script
# can easily destroy your savefiles and it is not recommended.
#
