# DL animation format
# XXX - collision with most `mips' magic
#
# I couldn't find a real magic number for these, however, this
# -appears- to work. Note that it might catch other files, too, so be
# careful!
#
# Note that title and author appear in the two 20-byte chunks
# at decimal offsets 2 and 22, respectively, but they are XOR'ed with
# 255 (hex FF)! The DL format is really bad.

# Based on empirical evidence, DL version 3 have several nulls following the
