## AI overview

Erico Mendonca's ESP32-C3 firmware connects to MiSTer's existing secondary display protocol and renders marquee artwork on panels such as the round GC9A01 or the rectangular Cheap Yellow Display. A web-based editor lets users create artwork tied to commands MiSTer sends, keeping changes on the display side without modifying MiSTer. The firmware can also be flashed through a browser, and one MiSTer system can control multiple client displays over WiFi. The excerpt does not specify setup requirements or limits.
