PKSE is an open-source Pokémon save editor that runs directly on a hacked Nintendo Switch console. It reads, edits, and writes save files in place on the console, so no PC, save transfer, or external tooling is required. SUPPORTED GAMES Gen 3: FireRed / LeafGreen Gen 7: Let's Go, Pikachu! / Eevee! Gen 8: Sword / Shield, Brilliant Diamond / Shining Pearl, Legends: Arceus Gen 9: Scarlet / Violet, Legends: Z-A Per-game save version and DLC detection is handled automatically. CROSS-GAME BANK PKSE includes a native storage bank shared by every supported game. A Pokémon deposited from one game is converted into the destination game's format on withdrawal, preserving origin data: OT, trainer IDs, met location and level, IVs, nature, and PID. EDITING Party and box Pokémon: species, level, stats, IVs/EVs (AVs in Let's Go), nature, ability, moves, held item, ball, OT/met/origin data, shininess, gender, and ribbons. Trainer info and item pouches are editable with per-game item and count limits enforced. A Pokémon creator builds an entity from scratch in any supported game's format, with legal values highlighted. LEGALITY A legality checker flags illegal values as you edit. It is informational only — it never blocks an edit or silently alters your data. Encounter matching is not yet implemented, so the checker should not be treated as a substitute for PKHeX's legality analysis. SAVE HANDLING Backup and restore are performed on-console with retained backup history. Users are strongly encouraged to take a backup with Checkpoint or an equivalent tool before first use. INTERFACE HOME-style UI built with NanoVG, 256px HD sprites, full touch controls, and scrollable storage and lists. REQUIREMENTS A Nintendo Switch running custom firmware with access to the Homebrew Menu. Place PKSE.nro in sd:/switch/. Tested on firmware 22.5.0. PKSE operates only on save data already present on your own console. CREDITS Built using PKHeX as a reference throughout — much of the format and structure knowledge behind this tool comes from that project and the documentation work of this community.
