#   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 = 4.0
# 
# 
# 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 CMSes that change music playing methods
#   in Game_System. NEEDS DREAM of the provided version or higher. Files will
#   be saved into "DREAM Encrypted Audio" format with .dea extension.
# 
# 
# Features:
# 
#   - encrypts your Audio files in a way, so you can encrypt them together with
#     Data Files and decrease the chance of music theft
#   - decrypts and plays the .dea files
# 
# new in v1.0b:
#   - rewritten conditions using classic syntax to avoid RGSS conditioning bug
#   - now beta
# 
# new in v1.01b:
#   - compatible with StromTronics CMS v5.0b and higher
# 
# new in v1.02b:
#   - improved coding
# 
# new in v1.03b:
#   - fixed a bbug cause by a typing mistake
# 
# 
# Configuration:
# 
#   If you set ENCRYPT_AUDIO to true the script will encrypt the audio files
#   you have specified in AUDIO_FOR_ENCRYPTION and exit the application. If you
#   have set ENCRYPT_AUDIO to false, you can play the game normally and the
#   script will play the newly created files. All files go into the Data folder
#   organized as if they were in the normal Audio folders.
#   
#   Examples:
#   
#   - old locations and names:
#     Audio/BGM/Outskirts.mp3
#     Audio/BGS/Blizzard.ogg
#     Audio/ME/Victory.mid
#     Audio/SE/Explosion.wav
# 
#   - new locations and names:
#     Data/Audio/BGM/Outskirts.dea
#     Data/Audio/BGS/Blizzard.dea
#     Data/Audio/ME/Victory.dea
#     Data/Audio/SE/Explosion.dea
# 
#   Put all files in the main game folder if you want to encrypt them.
# 
# 
# IMPORTANT NOTES:
# 
#   This script will encrypt audio files and save it into .dea format. A file
#   in .dea format can't be player by any normal media anymore, so be don't
#   delete your old files in case you want to edit them or anything similar.
#   If you use this script without having encrypted all your .dea files, your
#   game will crash.
#
