Frequently Asked Questions

How do I get my ACNH save to PC?

You need a homebrew-capable Nintendo Switch. Use save management tools like JKSV or Checkpoint to dump your save data to an SD card, then transfer to PC.

Can I add Bells?

Yes. Once you upload the save, search for your current Bell amount in the detected values and change it to whatever you want.

Can I change my villagers?

Villager data is stored in the save file. While the binary format is complex, you can attempt to modify villager-related values.

Is this safe for my Switch?

Save editing itself doesn't harm your Switch, but using homebrew carries inherent risks. Always keep a backup of your original save data.
