Very interesting paragraph ... I wanted to see if the forum would
tolerate my asking a question on this.
If doing a "black-box" only job of "reverse engineering" requires one to
load memory with a trademark, how does this fall into the realm of
acceptable?
Curiosity only on this question, as it would seem to me that such would
be an acknowledgment of ownership (as opposed to some random memory load
for "validation check"?),
Thanks,
Paul
