EDIT: Replace it with this full version that no longer includes any weird hidden character AFAIK.

# ** GW Animated Battlebacks + New Features
#------------------------------------------------------------------------------
#  by The Bard (Gabriel Winchester)
#  - Improvements by Atoa -

#
#  This screipt allows battlebacks to be animated (no, its not like Moghunter's
#  system which moves). They are actually animated, by individual frames.
#
#  USAGE
#  Before each battle, you establish the parameters you want for the battleback.
#
#  Use the call script command:  animated_bb_on(speed, frames, opacity_
#  * Opacity can be omitted as it is defaulted to a full 255 solid setting
#
#  To turn off the animated battleback layer, use: animated_bb_off
#
#  NEVER set a speed value to 0 or below.
#
#  UPPER LAYER
#  If you add a top layer to the battleback, the image will be above the heroes.
#
#  To set a top layer, use the code:  upper_bb_on(speed, frames, opacity)
#
#  If the image is not moving, just call: upper_bb_on
#
#  To turn off the upper battleback layer, use: upper_bb_off
#
#  Upper layers should have the suffixes "UP" and 'frame' followed by
#  each other. IF, for example, it is an image to be shown above the heroes
#  and has three frames of animations, they must be named as follows
#  "CastleUP1" "CastleUP2" "CastleUp3"

end

Now it would only fail if you lack any of the frames.
