Nintendo blocks flashcards with DSi firmware 1.4.1 do not update! Nintendo has just blocked flashards on the DSi yet again with the release of firmware update 1.4.1 today. However, it does not seem like all flashcards have been affected. Nintendo's system menu update page says the new firmware provides "behind-the-scenes improvements", but as expected that is really just PR speak for "no more homebrew for you". This is the first incremental update for the DSi in over a year, yet it is not believed there are any new features for the DSi outside of flashcards being blocked. Several GBAtemp users have updated and tested their flashcards and ended up with a black screen that tells them to turn off the power. The Supercard DSTwo and Acekard 2i are confirmed to be blocked, but resident AKAIO developer and flashcard wizz Normmatt says the EZ-Flash Vi and iSmartDS have not been blocked. We will keep a list of confirmed flashcards. Thanks to SickPuppy for the original tip-off on the forums about this update. For now, steer clear of the update if you want to keep using your flashcard!
