EDIT 2: SOLVED! I solved it myself, but that's beside the point. If anyone is having this same problem, just insert the R4 into your 3DS with a folded piece of paper on top of where the label is on the cart. That should fix it! Hello, I currently have an O3DSXL, and whenever I pop in my R4i card which is compatible with 3DS, the system crashes. Also, when the cart is inserted, my system fails to start up. Please help! EDIT: Added video to help explain my problem.
