I lost your original mail in my 7,000+ mail gnubg folder, so I'll just
reply here.

The binary gnubg.wd file that contains the weights are produced from an
ASCII gnubg.weights. You can download the gnubg.weights file from
Nardy's site (if I remember correctly). You can perturb that file -- I
can give you the specs later, or you can try to guess it from reading
the source lib/neuralnet.c

You can either run makeweights on the perturbed ASCII file or you can
delete the old gnubg.wd, in which case gnubg will use the ASCII
gnubg.weights file.
