My son has a DsiXL with an R4 Gold Pro cart from r4i-gold.com. It was working fine until today when you select the cart from the ds menu it got stuck on the 'Loading' screen. I turned it off few times and now both screens just stay white when you select the cart from the main menu. I tried formatting it and loading updates from the cart's site but no success. Is this card dead now ? Any help appreciated.
