Hi there, I am a new member but I've been keeping up with the forum for a while, one thing I found was that it was pretty hard to find was a confirmation from someone running 2.1.0-4E on their 3DS and the R4i 3DS SDHC flashcart working properly with its latest update (1.43 I believe). So I took a dive anyway, as I wanted to get in with this Ambassador program (which ends tonight and not last night I hope!), updated my own 3DS from 1.0.0E (?), the firmware it came with, straight to 2.1.0-4E through internet update, and the R4i 3DS is still working as it was before the update. In short, this flashcart is compatible with the latest Nintendo update, in Europe. This news may be present elsewhere in the forums, but I'll tell you what, if it is, it's damn hard to find.
