The DS experience, for every emulator.
Show live game data on your second screen, or on top of the game.

What It Does

EmuLnk connects to emulators over UDP, reads game memory in real time, and renders it as themed HTML pages. It supports three modes: full-screen dashboards on a second screen, floating overlay widgets on top of the game, or both at once (bundle). Themes are HTML/CSS/JS WebViews driven by live data from JSON profiles. Themes can also write back to game memory, run macros, play sounds, and trigger haptic feedback.

Screenshots coming soon

Supported Emulators

[!NOTE] Each emulator fork adds the EmuLnk binary UDP protocol. Install the fork alongside EmuLnk to use it.

1. Detect: Sends an EMLKV2 handshake over UDP; emulator responds with JSON containing game_id, game_hash, and platform
2. Match: Hash resolves to an exact profile, or serial falls back to a compatible one
3. Poll: Data points are read from emulator memory at a configurable rate (default 5 Hz)
4. Render: Live data is pushed to the theme WebView (full-screen dashboard or floating overlay widgets) via JavaScript bridge

Installation

Download the latest APK from Releases or import the full EmuLnk suite into Obtainium:

[!TIP] obtainium.json: Includes EmuLnk app + all emulator forks + repo tracking, grouped under one category. If you imported EmuLnk before the package IDs were corrected, delete the affected RetroArch, Dolphin, or PPSSPP entries from Obtainium and re-import this file.

Building from Source

git clone https://github.com/EmuLnk/emulnk.git
cd emulnk
./gradlew assembleDebug

Requires Android SDK 35 and JDK 11.
