I bought the recommended R4i 3DS RTS flashcart from ozmodchips.com today. It won't work in my DSi XL which was recently updated to v1.4.5A. I put the latest firmware on the card (I can confirm the icon is Dorasu) and yet I still get the "An error has occured" message. I've tried two SD cards freshly formatted to fat32. What am I doing wrong? Thank you.
