You need CFW to use a homebrew save manager to dump the save file.Hi again, so my sister very generously gave me her Switch since she never used it and I have it all set up, recovered my Animal Crossing island and am good to go.
I'm wondering if there's any way I can use the keys I recovered to restore my Splatoon 2 save data? Since it doesn't have cloud saving for some stupid reason. Maybe a way to boot into CFW from the SD card on the old broken Switch and somehow send the save to the new Switch? But I don't know if having the keys is enough to recover the save file, and since I wouldn't be able to get online or use OFW when booting from the SD card I'm guessing it's not likely to be possible.
Just thought I'd ask anyway because losing hundreds of hours and a lot of gear/clothes/pretty high rank sucks but all things considered not awful, just glad to have a working Switch again.
