Its no problem. I also just figured it out thanks to another user lol. This works out better for me too since I can save after the 3 hour mark anytime I want to transfer to the full game.
Save 0 is the autosave.
Save 1 is the one I edit. Its also your actual save. Just edit this one, don't forget to make a save backup of your original save incase anything goes wrong. Also load the edited save into the game.
Check my previous post that had pictures to help you edit the save file.
I use auto rcm booted with a hekate payload into ofw so I can still play my games. It gives me the option to run other payloads if I want to. It's a tethered boot ,but like you guys have said when will a switch ever run out of battery with sleep mode.
