I have a Switch and SX OS on a 200GB microsd, and the SX pro dongle. I've felt like this is not enough for me, and the card is also pretty slow on write speeds, so I'm thinking of upgrading my capacity and switching to atmosphere since SX OS seems to have a questionable future in front of it and is still stuck on the last firmware. At the same time, I want to set up an emunand - possibly play a few games online on sysnand, and maybe use emunand for online local multiplayer of a few games (there are utilities for this, right? which spoof local multiplayer but over the internet?). My Switch has not touched the internet since I got it, so I'm almost fully certain it is not banned unless I screwed something up. I do have AutoRCM set up on the switch.
So, I haven't really looked much into the current status of everything, but what would be the best way for me to achieve these goals? To have a sysnand for normal online play, an emunand that can possibly spoof local multiplayer for online use of some games (this isn't super necessary, but seems like fun to try out), and homebrew that will be able to update when new firmwares come out? Are there any potential pitfalls that I wouldn't know about or that have cropped up in the last few years of me not paying much attention other than just updating my SX OS and firmware when necessary? Am I right to think that this is possible, or should I expect to have one of the nands fully offline at all times?
Thanks in advance.
