Ok, so I'm late to the party because I was always weary about installing things through "unofficial" means, but I think I'm about ready to give these things a try, but I need some help and I have questions. I originally was going to go with Pasta, but I'm hearing it's pretty redundant compared to rxTools. My knowledge of "messing with the 3DS" revolves around the use of Ninjhax for homebrew, and spoofing my system through the browser to allow me onto the eShop from my current firmware.
I'm running an o3DS with 9.2.0-20U, and I'm looking to have the ability to install CIAs of games, homebrew, etc. Other than grabbing the latest beta (v3.0 beta 7?), what other sort of things will I be needing? What sort of things can I do, and what should I avoid doing (or more specifically, what should I stay away from within the system when it's running whatever it's running)? I don't think I want to mess with patching the AGB_FIRM unless it means I can run various GBA games not part of the Ambassador program (which I have), since CitrAGB is rather slow, even with dynarec. In fact, one of the reasons why I stayed away from such things is because of it all installing onto or modifying the sysNAND. Supposedly I can use emuNAND instead, right? But how would that work, and can I use it even though I don't have a Gateway card? Can I even put together an emuNAND from my system under 9.2 without a GW card? And would that affect the digital games I already own?
There's just so much I don't know, so I'm rather hesitant to do anything, as I might regret it if I make a mistake.
