I lost my old acekard ages ago so I recently bought a new one. It arrived at my house today and I was excited. I put all the files on the sd card and put it in my Dsi XL 1.4.3. It worked great and played games great. I used the dsi 1.4.4 and 3ds 4.0 update on it and it completed. When I rebooted my Dsi I came to the home menu, and I clicked on the acekard icon again. I played another game. I then powered off my Dsi XL and put my acekard into my 3DS 4.0. It didn't work, even though I updated it. Confused, I put the acekard back into my 3ds. It no longer shows up on the home menu. I even formatted the SD card with the formatter on the acekard website. Still nothing. Someone please help me fix the acekard that I just got today!
