Hard mod is essentially a hardware modification that requires soldering to backup/ restore your nand
It can be used to downgrade a 3ds that's running 11.0

gateway/sky3ds are flashcarts that allow you to run games/homebrew off the flashcart

Playing online should is fine with cias, there were cases for people getting banned playing the lurantis leak of moon/sun but pretty sure that was due to people playing online before it was released in their region

If emunand was banned sysnand would be banned too

You can switch between sysnand and emunand

if you have another console running cfw and it's already got legit purchases of the dsi ware games that were recently taken off the estore you can perform a downgrade on the target 3ds using this guide:
https://3ds.guide/dsiware-downgrade

otherwise you can do a hardmod/ hardmod downgrade if you are decent at soldering
Hardmod installation:

Hardmod downgrade:

If you do not own an already hacked 3ds with the dsiware titles and you have no soldering skills there's a thread on hardmodders by region
https://gbatemp.net/threads/list-of-hardmod-installers-by-region.414224/

If you get a 3ds running 9.0 it is incredibly easy to install cfw
without the need to downgrade or hardmod

Yeah powersaves can be used to replace a save file of oot with the exploit
i believe there is a post on gbatemp about it
