JKSV Game Save Guides

General backup guides only get you so far: the saves players care most about belong to specific games, each with its own workflow. This hub collects our per-game JKSV guides — editing loops, island and world backups, console transfers and emulator moves. Every workflow starts the same way, with a verified backup from JKSV, available on the download page.

All game save guides

• Pokémon backup & PKHeX workflow — export a folder backup, edit on PC with the free PKHeX editor, restore safely, with the original-backup rules.
• Animal Crossing island backup — the island is Device-Shared save data; how to capture and move it without the classic mistake.
• Minecraft world backup & resize — protect worlds stored in save data, and expand save capacity when a world outgrows it.
• Zelda BOTW & TOTK save transfer — move saves between Switch 1 consoles with matching users and in-game verification.
• JKSV & Ryujinx save transfer — exchange saves between console and the Ryujinx PC emulator, same game and version required.
• Export emuMMC saves to PC — harvest saves from emuMMC into a PC archive for editing, emulation and long-term keeping.

One rule runs through every guide: back up first, keep an untouched original, and verify in the game before deleting anything. Follow it and these workflows are reversible, controlled and safe for saves worth hundreds of hours.
