Well, I'm getting the "No Card" message on my R4. I've tried with the latest firmware (I have one from r4i-sdhc.com, because that's the site that the card shows and it's written into it), and with some more that I've found over the internet. Maybe there's something I've been missing. Or could it be that the Flashcard it's broken? I've bought it with an DSi XL three months ago. No results, even in my DS Lite.
