Because I'm using Gateway and have to remove/re-insert the SD card into the console to do this, I find I have to power off my 3DS in order to remove or re-insert the SD card. The official documentation (and popups in the in the 3DS itself) makes it clear the user should not remove or insert an SD card without the console powered off.
Realistically, should I continue to power off when removing or inserting it, or is Nintendo being too paranoid?
It's a minor inconvenience that I'm willing to put up with to be able to use PKHeX, but would be cool if there wasn't much danger in keeping the 3DS on and in Gateway Mode throughout this process.
Edit: Nevermind, I'm stupid. EmuNAND is on the SD card. Don't mind me!
