Hi, total idiot here. I hacked my Switch today just so I could edit my save file after unwittingly trading a shiny I hatched for what turned out to be a hacked Pokemon, and now when I run the game while using CFW, it uses the updated save, but if I turn off my Switch and run it normally, the game loads up with what looks to be my original, pre-modified save.
For the record, I used Checkpoint to back up the save, transferred it to my PC to use PKHeX, then moved it back to the Switch and restored via Checkpoint using the now-modified save. Any idea if I might've unknowingly skipped a step along the way? Is there something I need to do to make the save "stick"? From my experiences so far, I'm starting to think that, if I restore my clean NAND backup as planned, I'll be forced to use my old save, which I guess isn't the end of the world. Makes me wonder how the people who trade hacked Pokemon do it, though, since I was under the assumption that going online while running CFW was an instant ban.
