Okay thanks. The whole point of me trading my sky away was because now I could install CIAs to my emunand. I have CFW, so I'm not to worried. Is it difficult to update the firmware on one of these bad boys? I would assume it's no more than a drag and drop. And just to be sure, this is the one that doesn't have a wifi logo on them. Most cards I found like this had that logo, so I was confused.
Also, do I need or not need to download a custom TLW_FIRM? I have seen varying answers so far. Thanks in advance, by the way!
Edit: I plan to download play from my 3DS to my girlfriends DSi, if that matters at all.
