Look, there's a lot about this stuff that I don't understand, but let's say that I have 4.2 sysNAND and 9.8 emuNAND (currently the latest version). Since I have to update my emuNAND to play my games online (in order to get the new game patches from the eShop), is it possible that a firmware update in the future (that I use to update emuNAND only and obviously not sysNAND) could stop emuNAND or things like FBI Installer and SaveDataFiler from working correctly? That's a scary thought, and these things are pretty important, and I want to be sure that I can use them no matter what Nintendo does. After all, they do whatever they can to make sure stuff like this doesn't happen. So what are your thoughts of my bolded question?
