this could be good ammunition:http://www.gamefaqs.com/features/help/entry.html?cat=24
specifically, "Is it legal to make a copy of a game I own?"
their answer is "Yes", with the caveat that the DMCA can make breaking "copyright protection" (sic, they must mean "copy protection": http://en.wikipedia.org/wiki/Copyright_protection
) on a game illegal. that caveat doesn't apply to FF6/3, because:
1) it precedes the DMCA by 4 years.
2) it doesn't have copy protection.
since it's legal to have a copy of your game, then any linkage to sites that discuss hacking said copy (but not how to obtain a copy) can't be illegal either.
now, this FAQ is part of the general "GameFAQs Help" rather than the messageboard specific rules. however, one would think that something qualified as "legal" on one part of the site couldn't be an "illegal activity" on another part. prohibited, maybe, but deemed "illegal" by the same admin who just said otherwise? hah.
