Well, I did a little research suffice to say V.5 should work on the card, correct? It is a marked V4.5 card. Before update supported V4.5 perfectly. The kernel of my R4 is Ver.1.67b. (Says so in the corner) However when I go into Update it supports only the following: "Current Version Support Model: NDSL, NDSI 1.44, 3DS 4.4" I updated it via my old DS (Since I could never get updating via PC to work) I have a 3DS XL updated to the following: V220.127.116.11 The R4 card is not working on the system. So does anyone know what the problem could be? UPDATE: Just checked it on another console running the V4.5 and it is no longer working. Thanks in advance.
