I haven't checked the DSiWare shop in a while, but now it's trying to update my system. I'm running on 1.4U at the moment, and it's saying there's an update. Will the update block my flashcart's? I have a SCDSTwo and an Acekard. The main reason I'm scared is because I have to send my DSi off to Nintendo (randomly powers off when I shut it), and I don't want to get it back flashcart-proof.
