A 2026 reimagining of Mii exploration — not just a sharing platform, but a living digital museum where every Mii becomes a storyteller, a traveler, and a tiny echo of global creativity. Welcome to the crossroads of Nintendo's charm and PC-scale ambition.
Imagine if a Tomodachi Life island could breathe beyond the constraints of a single console. Imagine Miis not as static avatars but as cultural artifacts, each carrying a unique personality fingerprint, a migration history, and a social DNA that evolves across users.
This repository is the engine behind that dream. A Mii-sharing ecosystem that bridges the Nintendo Switch (emulated or native) with a desktop-class life simulation experience. It's not about extracting data — it's about liberating stories.
| Traditional Mii Sharing | This Project |
|---|---|
| One-time QR code exchange | Persistent Mii migration with life logs |
| Static appearance data | Trait-based personality inheritance |
| Console-locked existence | Cross-platform Mii pilgrimage |
| Silent transfer | Narrative-driven arrival scenes |
We believe every Mii deserves a backstory, a travel diary, and a future. This is the anti-loneliness software for your digital companions.
- Run multiple Tomodachi Life instances on PC simultaneously
- Miis can visit, trade, or permanently migrate between islands
- Each island has its own weather, economy, and social mood — Miis react accordingly
- Extends the standard Mii format with a 16-trait personality vector
- Traits influence conversation topics, gift preferences, and even relationship success rates
- Trait inheritance: children Miis blend parent profiles with emergent mutations
- Browse a living gallery of community-created Miis, each tagged with descriptors like "grumpy chef," "wandering bard," or "secret agent gardener"
- Miis arrive via simulated boat or plane — with full animation sequences
- Rate, remix, and re-release Miis under the Creative Commons Mii License
- Every Mii retains a memory queue of their top 50 experiences
- Memories influence future behavior: a Mii who loved the beach will seek water views
- Export memories as short stories or dialogue logs for fan writers
- Full facial geometry control beyond standard sliders
- Import real-world photos as texture guides (not face mapping — artistic inspiration)
- Export as standard

}Launch the Mii discovery daemon with a fully themed interface. This spins up the Community Wharf service, opens the Appearance Forge, and begins broadcasting your local Miis to the federation.
tomodachi-share --mode daemon --port 2026 --ui-theme seafoam --broadcast-profile captain_barnacle.json
Expected behavior on execution:
- Terminal displays a stylized ASCII compass that rotates as Miis are discovered
- A local web dashboard opens at
http://localhost:2026/wharf - Nearby federation peers (if any) begin exchanging Mii packets
- A simulated foghorn audio cue announces new arrivals

Every Mii is a seed. Every migration is a pollination event. This is the garden loop.

The Community Wharf automatically translates Mii profiles, memories, and catchphrases into the viewer's locale. Supported language families include:
- English (UK, US, AU)
- Japanese (with honorific preservation)
- Spanish (Latin American & Iberian)
- French (European & Canadian)
- German, Italian, Portuguese, Russian
- Korean, Chinese (Simplified & Traditional)
- Arabic (RTL interface support)
Translations are context-aware: a Mii's "grumpy" trait might render as "gruñón" in one scenario and "malhumorado" in another, depending on the memory being described.
This project supports optional narrative enrichment via third-party AI APIs.
- Memory Storytelling: Send a Mii's memory queue to GPT-4o and receive a 300-word narrative in the Mii's voice
- Dialogue Generation: Create full conversations between two Miis based on their personality vectors
- Personality Expansion: Generate new trait suggestions based on existing data
- Ethical Personality Profiling: Claude's constitutional AI approach helps ensure Mii traits remain respectful and inclusive
- Cultural Sensitivity Review: Before a Mii migrates to a region with different cultural norms, Claude reviews the profile for potential misunderstandings
- Dream Journaling: Claude can generate "dream sequences" for sleeping Miis, adding surreal lore
Important: All AI features are opt-in via a
config.securityflag. No data leaves your machine unless you explicitly enable cloud enrichment.
The web dashboard (Community Wharf) adapts to:
- Desktop (1920x1080+): Full island map view with Mii migration trails
- Tablet (768px-1024px): Condensed profile cards with tap-to-expand
- Mobile (320px-480px): Single-column feed, swipe to browse Miis
Built on WebSocket real-time updates — when a new Mii arrives at the wharf, every connected device sees the boat dock in sync.
This repository comes with a companion signal for real-time support:
- Dedicated chat channel for federation troubleshooting
- Weekly Mii migration events where the community sends Miis to a central "grand island"
- Emergency profile recovery — if your instance crashes, your Mii archive can be rebuilt from federation backups
Support is provided by community moderators and maintainers on a follow-the-sun rotation. No automated bots — only human Mii enthusiasts who understand the emotional weight of losing a digital friend.
