I just bought two used R4 cards, and when I plug them into my DSI (v1.4.3u) they show up as "ALEX RIDER STORMBREAKER THQ" and clicking them just leads to a message saying an error has occurred. I confirmed the WIFI R4 as being authentic via its website. Is the yellow card authentic too? Which of these cards is better to use? Are they any good in the first place? I'm guessing that to get them to work they need to be updated or something. I haven't the foggiest how/what to update them to. I've gone from thread to thread and just keep getting more and more confused. The cards' own websites are hard to decipher. What's the best update for each of them? Any help is sincerely appreciated. Thank you.
