Just got a new Acekard 2i as my old M3 doesn't work anymore/isn't getting updated. I formatted my microsd, put the new firmware on it then tried to play. I get the japanese game icon, but when I click it gives an error and I have to reset. My 3DS is on firmware 3.0.0-6E, the acekard firmware is 1.8.9z. Sorry I haven't used flashcards in a while, i'm probably missing something vital.
