So, I finally got around to following the 3DS Guide, step by step (huge props to the people that put that together) and getting everything installed and going. I did everything except for the System Update and the entirety of Section VIII - CTRNAND Luma3DS. And, I injected FBI. Couple questions arise, though... before doing a System Update, I'm most interested in messing with Freeshop and some emulators. 1. Is it okay to update to the latest System Update, now? Or, should I mess with backing up CIAs of my physical game collection, Freeshop, emulators, etc. first, THEN update? 2. Can CIAs be be updated, as well? 3. Secondly, can someone put into layman's terms what Section VIII does? 4. What is the difference between installing a CIA to play a backup and installing a Title Key? 5. What's the difference between an Encrypted Title Key and a Decrypted one? I'm currently on an O3DS with 11.2.0-35U. Sorry if these seem like dumb questions, but prior to installing all this stuff, I ran into some really great people here and truly appreciate this community of helpful people. Thanks for any and all help!
