I just got the Acekard 2i 1.4 firmware update and now I've got some questions about it. Is it possible that when you update your Acekard 2i with the update, it will fail? The update is real right? And it works? What if it fails, what happens then? Can you start over with the update or not? When you have updated the Acekard 2i firmware, you update your NDSi firmware and then still safely play with the Acekard 2i?
