Hi everyone! I just released Web-mGBA, a web-based port of the highly accurate mGBA emulator.
The biggest feature of this project is seamless P2P online multiplayer. You can load your legally obtained ROMs and connect with your friends directly in your browser using a lightweight relay server. No heavy game installations or complex setups are required!
