#  Extra Movement Frames v. 1.0
#  Author: modern algebra (rmrk.net)
#  Date: January 20, 2008
#------------------------------------------------------------------------------
#   Instructions:
#     Insert this script above main in the database. To add a character with
#     extra movement frames, simply rename the character graphic to something
#     of the form: 
#          !$%[<number of movement frames>]<Regular name>
#
#     Example: !$%[4]001-Fighter01    
#     That would make the graphic 001-Fighter01 be interpreted as having 4 frames
