Ollama 3DS is a homebrew application for the Nintendo 3DS family of consoles that connects to an Ollama server running on your local network and lets you perform LLM inference directly from your handheld.
Type a message using the 3DS software keyboard, send it to any model running on your PC, and read the response - all from your couch, with a 3DS in your hands.
Requires a modded 3DS with the Homebrew Launcher (e.g. via 3ds.hacks.guide) and an Ollama server running on your local Wi-Fi network.
Features
- Full chat interface - Send messages and receive responses from any Ollama model.
- 5-message conversation context - The last 5 exchanges are remembered and sent with each request, giving the model conversation memory.
- Multi-language UI - Switch between 7 languages at runtime:
- English
- Italiano
- Français
- Español
- Deutsch
- Українська (romanized)
- 日本語 (romanized)
- In-app configuration - Change IP, port and model name on the fly, no recompilation needed.
- Persistent settings - Configuration and language choice are saved to SD card (/3ds/ollama3ds/config.ini) and restored on next launch.
- Memory reset - Clear conversation context instantly with one button.
- Dual-screen UI - Top screen shows the chat, bottom screen shows live context preview.
- Credits screen - View tools, libraries and author info.
