After looking through countless topics and rumors, I'd like some confirmation. So far I think from what I hear... Nintendo tries its best to limit Flash card marketing. Most bans on Nintendo products would be on the Wii or for A/P on games. But like, do they ban you for going on Wifi/WFC while using a Flash Card/ROMs. I.E. If you're running a Pokemon rom on your R4/M3 or what-not, do they check for game serials, and Ban your DS/Mac Address if they find something suspcious? Thanks for your answers in advance.
