# The first part of the pattern, \x11\x20\x01\xa0\x98\x11, has to be 
# modified for different version of Battlefield 2. The gameplay part of 
# pattern for BF2 v1.4 is \x11\x20\x01\x30\xb9\x10\x11, and for BF2 
# v1.41 is \x11\x20\x01\x50\xb9\x10\x11
#
# Rather than put all of those in, I've just gone with "...?" in the 
# middle.
