Since we got multiple threads where people ask this over and over let's make it clear. We know nothing how Nintendo will detect homebrew, backup loaders, save editing or any of those things at the moment (2018-06-14) No, Emunand won't make you safe. No, deleting past history at the moment won't make you safe. No, going from CFW to OFW will not make you safe. At the moment we don't even know if they can detect you booting RCM. They might already have that info. You hack your console, you take a risk. A risk to get banned. Else the only sure fire way not to get banned is to pay and play legit. Buy your games, buy your DLCs, don't use cheats.
