This morning, my Acecard 2i suddenly stopped being read by my XL. It's the red special edition Mario Kart one, if it matters. It was working perfectly fine up until a few hours ago and the only thing I did was put Diddy Kong Racing on it. I've tried formatting it and reinstalling the latest AKAIO firmware. I tried switching SD cards, no dice. Will I just have to replace the card, or is it possible to get fixed?
