What Shin Pokémon Save Editor is

Shin Pokémon Save Editor is a browser-based editor for Shin Pokémon and Generation 1 Game Boy save files. It works with parsed 32 KiB battery saves; when a file is not edited, the editor says its export matches the original byte for byte. The maker says saves stay in the browser, with no upload, account, or backend. Users can edit trainer details, party Pokémon, all 12 boxes, inventory, Pokédex status, story events, and Hall of Fame records. Party and box tools support PKHeX-compatible .pk1 imports and exports. The editor checks main and per-bank box checksums and repairs ones made stale by edits. Other tools include semantic comparisons, a highlighted raw hex view, and Test Drive using a user-supplied ROM. It is an installable PWA with offline support and undo and redo history capped at 200 snapshots. The project is an unofficial fan tool, is MIT licensed, and does not distribute ROMs.
