Erico Mendonca built it for the ESP32-C3 to work with MiSTer's existing secondary display protocol, supporting round GC9A01 panels or the rectangular Cheap Yellow Display. The firmware handles all the artwork rendering itself, with a web-based editor for designing what shows based on MiSTer's commands. Flashing is done through the browser, and the system can control multiple client displays over WiFi at once. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I show the current game or core on a secondary display for my MiSTer FPGA setup? A firmware project by Erico Mendonca runs on the ESP32-C3 and connects to MiSTer's existing secondary display protocol, letting you drive more visually interesting panels than a standard monochrome OLED. It supports round GC9A01 displays as well as the rectangular Cheap Yellow Display, and includes a web-based editor for designing artwork along with browser-based firmware flashing. _Builders customizing MiSTer setups can track hardware projects like this one on daily.dev._ ### Can one ESP32 marquee firmware control multiple displays at once for a MiSTer system? Yes, the ESP32-C3 firmware built for MiSTer secondary displays supports controlling multiple client displays simultaneously over WiFi, so a single system can push the same game or core artwork out to several screens at once. _Retro-gaming tinkerers wiring up multi-display rigs can follow builds like this on daily.dev._ ## Similar posts on daily.dev - [A Cheap And Easy Control Screen For Home Assistant](https://daily.dev/posts/a-cheap-and-easy-control-screen-for-home-assistant-rb9h4sswz) · Hackaday · 0 upvotes · 0 comments - [I connected a local LLM to a $30 ESP32 display, and it designs a new screen for every question I ask](https://daily.dev/posts/i-connected-a-local-llm-to-a-30-esp32-display-and-it-designs-a-new-screen-for-every-question-i-ask-hewzqepyu) · XDA Developers · 0 upvotes · 0 comments - [Bare-metal MSX2\+ Emulator for ESP32-S3 offers custom LCD\_CAM VGA implementation & Z80 optimizations](https://daily.dev/posts/bare-metal-msx2-emulator-for-esp32-s3-offers-custom-lcd-cam-vga-implementation-z80-optimizations-kmxn61vlw) · CNX Software · 0 upvotes · 0 comments - [Elecrow CrowPanel Advanced HMI Display Review: A Tinkerer's Touchscreen](https://daily.dev/posts/elecrow-crowpanel-advanced-hmi-display-review-a-tinkerer-s-touchscreen-9akh9nkvh) · It's Foss · 0 upvotes · 0 comments - [This ESP32 project couples a simple clock with some iconic retro gaming references](https://daily.dev/posts/this-esp32-project-couples-a-simple-clock-with-some-iconic-retro-gaming-references-2b1omg9og) · XDA Developers · 2 upvotes · 0 comments --- Tags: [#gaming](https://daily.dev/tags/gaming), [#hardware](https://daily.dev/tags/hardware), [#iot](https://daily.dev/tags/iot) [View this post on daily.dev](https://daily.dev/posts/putting-a-mister-marquee-on-a-better-display-vswa8rdbt) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Putting A MiSTer Marquee On A Better Display","url":"https://daily.dev/posts/putting-a-mister-marquee-on-a-better-display-vswa8rdbt","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/putting-a-mister-marquee-on-a-better-display-vswa8rdbt"},"datePublished":"2026-10-30T02:25:46.238Z","dateModified":"2026-10-30T02:26:08.918Z","description":"A firmware lets MiSTer FPGA users drive fancier secondary 'marquee' displays instead of the usual small monochrome OLED.
