When I insert my r4 (r4igold.cc) or the gw blue card, the 3ds doesn't show anything. I don't think it's a software problem, as I have a 10.7 a9lh eur new 3ds xl with luma cfw, l2 and clock off. The original ds and 3ds games are working on it, so it's not an hardware failure. I heard that the problem could be the shape of the card. How can I solve this?
