Hi everyone! Long time lurker but created an account today and am going to get into the switch hacking scene cause why the hell not!? I have had some experience getting homebrew and usb backups working with my Wii (years ago) so have some understanding on how things work but wow, the switch is very different.
I am planning on following a guide from github (unable to post a link cause I'm brand new, but can give more details or be more specific with what guide I'm using later on I guess) and have an rcm jig arriving in the mail later today. The guide runs through everything from entering rcm to creating a NAND backup, creating emuNAND, dumping keys, etc.
My switch is unpatched as I got it a few days after launch. I am also running the latest firmware (11.0.1 I believe).
I just wanted to clarify a few things before I get started. I have looked through the FAQ and read several pages from this thread but naturally I can't really go through all of it as I would die of old age before I finished reading it all haha. Anyway... Here we go:
I am to understand that sx os is no longer supported, (RIP xecuter

) and also not available for my firmware anyway, so I will use atmosphere.
I won't be able to load xci with atmosphere and will have to convert them to nsp to install, and that tinwoo is able to do this? Not totally sure if I can have the xci on the SD card or if I will have to use nsusbloader to send them over from my PC.
I am not planning on using the switch online while using atmosphere, so I will have to install my homebrew apps via USB loading (maybe called payload injection? Not sure as I haven't actually started messing around with it yet).
I would like the option to play online if I so choose. My understanding is I can simply power off the switch, remove the SD card, and turn it on and it will load into stock firmware, then it is safe to use the internet. I have already copied Mario kart over to my system memory, as everything else I plan on playing will remain on the SD card and I'll just be playing single player offline.
To get back to cfw I can just delete my wifi connections, power off, put in my SD card, put in the jig to enter rcm and boot atmosphere from emuNAND and then I'm good to go as everything will be installed to the SD card.
Lastly, the jig is only required to enter rcm and once the switch is there I can remove it? Some of the guides aren't very clear on when I can remove the jig and slide my joycon back on.
Sorry for the wall of text, just wanna be sure I'm heading in the right direction! Thanks to everyone for all of the info so far. Excited to get started!
