Project description
📌 Overview Robert Dale Smith, founder of Joypad, maintains Joypad OS as an open-source firmware platform for controller adapters, custom controllers, and assistive input devices. The repository now contains a W5500-based GBA-to-Dolphin Ethernet bridge alongside MCP, vision-agent, and robot-learning experiments. The important word is "alongside." The W5500 target carries real GBA Joybus traffic to Dolphin over TCP. The MCP path sends controller states over UART, while the VLM and LeRobot paths currently operate with a software NES emulator. They share one repository, but they are not one…
