4.4 Import/Export Workflows

  • Single-file import: load a save, open a slot/box, import a .pkm to a PC slot.
  • Batch operations: mass import/export via folder selection and naming conventions; save ripping for backup.

Why Use an Older Version Like 22.12.18?

You might be wondering: “If newer versions exist, why seek out this specific build?”

7. Saving & Exporting

  • Click File → Export Save → choose main (Switch) or game.sav (3DS/DS)
  • Copy back to your SD card (same folder you dumped from)
  • Restore save using JKSV/Checkpoint (Switch) or JKSM (3DS)

⚠️ Always keep a backup of your original save before editing.

1. Core Support for Pokémon Scarlet & Violet (Gen 9)

Earlier builds could read SV saves, but 22.12.18 introduced robust handling for:

  • Terastal Phenomenon data – Proper flags for Tera Types.
  • Picnic and Egg Power mechanics – Supporting the new breeding system.
  • Raid dens and event spawns – Allowing injection of unreleased Tera Raid events.
  • New held items – Including Mirror Herb, Loaded Dice, and Clear Amulet.
