Ich hab was für den RMXP gefunden der dieses Problem lösen dürfte:
Code:

# Script by: BEHEMOTH # #
####################### #
#Version: 1.0 #
#Date Created: October 26th 2006 8:42 PM (Eastern Standard Time) #
#Description: An encryption script for audio files. #
#Thanks goes to thephantom from http://www.phanxgames.com/ for pointing out #
#the whole encryption key idea which I was too blind to see. #
#############################################################################
#############################################################################
# ***IMPORTANT RESTRICTIONS*** #
#1) If the audio file is an .mp3 file, it will NOT encrypt the file and it #
#will play it normally. If you wish to have your mp3 file encrypted please #
#save it as another compatible audio file, such as .ogg, .mid #
#or .wav(compressed of course) or .wma #
# #
#2) Your audio files must NOT be: read only, or hidden, or protected in #
#anyway or it will not encrypt the file and it will play it normally. #
# #
#3) Audio files should not have the same filename with a different #
# extension. #
# BAD: "battle01.mid" "battle01.ogg" #
# GOOD: "battle01.mid" "battle02.ogg" #
# #
#4) Files from an RMXP RTP will not be encrypted and will play normally. #
#############################################################################

# ***NOTES*** #
#Positives: #
# - Protects your own custom audio files #
# - Gives a point to having a BGM test inside your game #
# - Ummmm.......it's cool #
# #
#Negatives: #
# - Audio files take slightly longer to load #
# - mp3 files do not encrypt #
# - Once encrypted, audio files will not play in rmxp gui, only in the game #
# - The audio file is slightly bigger in file size then the orginal file #
# #
#If you have problems, suggestions, comments about this script then you can #
#currently find me here: http://www.phanxgames.com/forum/ #
# #
#How to Use: #
#To encrypt your audio files play the file in your game at least once. #
#The script will handle the rest. MAKE SURE TO BACK UP YOUR ORIGINAL #
#AUDIO FILES BEFORE ENCRYPTING IT, because it automatically overwrites #
#the original file with the encrypted file. To make this script encrypt #
#only certain audio files such as BGM, BGS, ME, SE then change the values #
#of the variables below named: #
#ENCRYPT_BGM, ENCRYPT_BGS, ENCRYPT_ME, ENCRYPT_SE #
# (located below class Game_System) #
#changing the value to true means those files will be encrypted and false #
#means those files will not be encrypted. Changing these values when an #
#audio file is encrypted may cause undesired results. So choose what you #
#want first then start encrypting your audio files. Deleting the Encryption #
#key file (default = "audio.edat") after encrypting your audio will also #
#result in undesired results....so don't delete or move that file once #
#you've been encrypting or else you'll have to start encrypting all your #
#audio again. This script is more for people who create their own audio #
#files. #

Ich weiss allerdings jetzt nicht in wie weit man es für den VXAce umschreiben müsste....
