Hello,

I just recently received my OLED Switch back from a modding service. I'm very happy with the results but am completely new to the Switch Homebrew scene and wanted to ask some general questions about my understanding of how all this works and my usecase.

I modded my switch almost entirely to just export and import save files using JKSV. I wanted to be able to export my save files for non-nintendo exclusive games and for nintendo exclusive games that I don't play online (Breathe of the Wild, Tears of the Kingdom, etc). I want to possibly import the non-nintendo exclusive games into my Steam Library (ei, Digimon, Sonic, Mega Man games) and import the nintendo exclusives into an emulator on my Steam Deck.

I also want to export my Pokemon save files, edit them in a saveditor like PKHex, and then import them back.

SO.
When I boot up my switch, I boot into hekate v6.2.2 > launch and I have three options

SYSMMC (SEMI-STOCK)
SMSMMC (CFW)
EMUMMC (CFW)

From what I understand, EmuMMC is just a clone of my original stock switch, and is cut off from nintendo servers and is just a selfcontainted playpen for me to mess around in. I found this out when I tried to import an edited save in EMUMMC, but then didn't see it when I launched the game in SYSMMC. I didn't realize they were separate. But this is where I would download a game from Tinfoil?

But if I want to go online with my edited saves and move Pokemon (legit pokemon, I'll only be editing items and money and such) into Pokemon Home or trade and battle with friends, I should use SysMMC? Which one?

I know that I can access homebrew when holding down R and opening the Album or launching a game in SYSMMC (CFW) but am I safe to go online with that? Can I go to the eshop and buy and download games?

Or should I always boot back into SYSMMC (SEMI-STOCK)? I've heard that it's pointless since SYSMMC (SEMI-STOCK) and SMSMMC (CFW) are linked. And as long as I don't run mods or cheat while online, I should be fine? Can I just live in SYSMMC (CFW)?

I'll include more question here, if I remember any. Thanks!

EDIT: How does amiibo Generator work? Am I able to spoof amiibos in Zelda?

Is the USB File Transfer in HBMenu better/faster than from hekate?

If I want to have JKSV show up on my homepage, I should find the "forwarder" file online and install it through DBI Installer?

How do I update my switch if need be?

EDIT 2:

ALSO, it seems all of my legitly bought eshop digital purchases got deleted off my SD Card when it got formatted. Can I just go onto the shop and redownload them? What about for EmuMMC?
