For some reason, my 3DS (Ver. 2.1.0-4E) won't recognize my M3i Zero (Original version, not GMP-Z003), while DS Lite recognizes it perfectly fine. I have the latest F_core.dat installed, I have tried it with the M3 Real Firmware on it, with the M3 sakura firmware on it, with WoodYS on it, but my 3DS just won't recognize it. When I insert the M3, my 3DS acts like there is no card inside at all and shows a white icon (So the icon stays empty, while it has to show the chessmaster icon). The DS Lite recognizes the M3 just fine and shows the Chessmaster icon and boots it up just like it has to. My 3DS-slot is not broken, because both legal 3DS-games and legal DS-games just show up and boot just fine on it. What's wrong and how do I fix this?
