(GEN) Secret passwords :
*BUG PASSWORD* means this pass not meant to be existed even as secret, code replaced by $FF as dummy, wrong password but programm ignores hi bits and uses only 5 low, so we have symbol $1F there, the same as "5". There is more than one "dummy" passwords in table, but matches always very first.
