Sounds like the application is looking at the value
of the `$HOME` environment variable.  For root, that
could well be set to `/root`.  Perhaps run a short
shell script that sets up the environment the way you
want and the invokes the binary.  Something like,

#!/bin/sh
set -e
HOME=/home/bbsuser
export HOME
cd $HOME
exec ./whatever
