I have my MiSTer setup now and I'm wondering if it's safe to do updates via SFTP instead of having to move the SD card to a different machine.
If I connect via SFTP I see that the config directory, cores, system, and menu files are within /media/fat
I assume it's safe to edit the config files that way while the MiSTer is turned on (though changes might not be reflected till a restart), but is it also safe to replace or add core files? What about updating the menu or system file?
Also, one more unrelated question: When I want to shut down, is it safe to just pull the power? I haven't found any alternative way, and just want to make sure I'm not risking corrupting the filesystem by doing that.
