^ As in, 1. What are the advantages and disadvantages that come with keeping SysNAND and EmuNAND linked? I've heard the thing about Data Management deleting invalid installations, does this mean I'll have to back up my SD card if I want to manage StreetPass titles? 2. What are the advantages and disadvantages that come with unlinking SysNAND and EmuNAND? I've heard that there are some things about Savedatafiler compatibility, and I take it that purchases made on one NAND can't be used on the other. Thank you!
