Nice！the r4i gold deluxe edition card released the great news again , and I always wait for the great news of it, i really want the firmware v4.0B2 will released soon so we can play multi-games on r4i gold deluxe edition cards.
i think you mean the r4i gold rts card,if that it can directly support the 3ds v7.2.0-17, if not the r4i gold rts card you can view the official website update, whether it can support the v7.1.0-16, it release on the official website..
