I just installed two legit on 10.3 via FBI after so many failed tries two days ago. Although I have updated my n3ds to 10.4 yesterday, which means FBI and NASA does not work, at least in short days, I still want to know the answer to two questions. 1. I saw L button could change destination of CIA in FBI: SD (about 2.8GB free) or Sysnand (about 600MB free). I installed on SD. Any difference? 2. I remember I saw threads telling that legit CIA could not get version update from eshop. Then could it use update installed already? for example, I have a mario kart 7 cartridge and get a update from eshop. Then if I install legit CIA of mk7, could this CIA use the update of mk7 cartridge that has been installed? 3ds, cartridge and CIA are in same region (US). Thank you very much.
