With all these people getting banned for using public headers, I've been wondering, a) Can Nintendo ban people from using private headers from different games? b) Can Nintendo tell when a header has been used on more than one game, even from the same console? I mean, the only reason ever to not use the header that came on the rom is piracy, and people who pirate generally don't own the game they are pirating. So people who play online with pirated roms end up using headers from their other, preferably offline only games. But what if something in the header of offline only games tells Nintendo something is wrong? Or what if the ID for the game, or information about the card type or w/e is in the header, and that tips Nintendo off? If somebody uses the same private header for all their .3dzs (which is stupid I know, but someone might forget and reuse a header) can Nintendo pull up an archive of use of that header online, and see that this header that was used for Mario Kart a year ago is now used for Smash Bros, even though the header is coming from the same console? Ugh. So many questions.
