Tomodachi Life: Living the Dream - Save Editor

A browser-based save editor for Tomodachi Life: Living the Dream (Nintendo Switch). Drop your Mii.sav, Player.sav, and Map.sav files in, edit, and download a patched copy. Everything runs locally - files never leave your machine.

Features

• Player tab - global/player state from Player.sav.
• Mii tab - per-Mii editing from Mii.sav.
• Map tab - island layout from Map.sav, with placement-aware footprints sourced from the game's WalkingGrid data.
• UGC editor - replace UGC textures (clothes, food, goods, exteriors, interiors, map objects, map floors) with your own images.
• ShareMii - import and export Miis and UGC items between save files, compatible with the ShareMii file format created by Star-F0rce.
• Advanced - raw hash-keyed entry browser for fields the structured tabs don't cover yet.

Adding a Localization

Translations live in messages/<locale>.json. en-US is the source of truth; locales are auto-discovered at build time.

1. Create the file. Copy messages/en-US.json to messages/<locale>.json (e.g. de-DE.json, ja-JP.json).
2. Backfill keys. Run npm run i18n:sync to mirror the en-US structure into your new file.
3. Translate. Edit the values.
4. Verify. Run npm run i18n:check, then npm run dev and pick the new language from the switcher.
