Generate a Warcraft II mixed-mode CD from mp3 and data files

# Gammies attempt to reconstruct the original 
# Warcraft II - Tides Of Darkness DOS/WIN95 CD.
#
# The copy I obtained from myabandonware.com had
# been incorrectly ripped, with the audio tracks being 
# garbage (verified by converting the bin to wav).
#
# What you need:
# - The original game files
# - mp3 versions of the original 16 audio tracks (2-17)
# Plase the game files in files/game, and the mp3's in 
# files/audio_mp3/
