Is there any way that I can inject an old garden.dat backup into a game that has already been updated? Or, does anyone know if I could overwrite an updated New Leaf cartridge with a pre-updated Powersaves backup without causing any kind issues?
Sadly no.. if the game is already updated, I doubt there's a way to revert it back unless you play on a ds that havent had the update installed in and that is not connected to the internet. I tried doing that on my 2ds that is still on firmware 11.0 and always offline and it worked just fine with garden.dat
