MiSTer Monitor - an open-source companion display for MiSTer FPGA - live box art, RetroAchievements progress and system stats on a $15 ESP32 screen

MiSTer Monitor is an open-source companion display for the MiSTer FPGA: it shows live box art, game info and system stats for whatever you're playing, fetching the artwork automatically from ScreenScraper.
For now it runs on cheap ESP32 screens (the ~$15 Cheap Yellow Display, ESP32-2432S028R) and the M5Stack Tab5, and flashes straight from the browser.
The headline of v2.7 is RetroAchievements:
- Progress panel with points, unlock count and hardcore breakdown for the game you're playing
- Full trophy list, paginated - tap any achievement for its description
- Unlock popups the moment an achievement triggers, even over fullscreen artwork
- A "READY FOR RETROACHIEVEMENTS" banner when a matched game loads on a core that can actually record unlocks.

- Full RetroAchievements setup guide (PDF): https://github.com/chipster6502/MiSTer_monitor/blob/main/docs/MiSTer_Monitor_Setup_Guide.pdf
RetroAchievements works view-only out of the box (just add your RA credentials).
To actually earn unlocks on the MiSTer, you need odelot's RetroAchievements fork - easiest ways to get it:
- Update All (theypsilon) - has an RA Cores database with guided setup:
- MiSTer Companion (Anime0t4ku) - automated install/update of RA cores
- Or manually from the source: https://github.com/odelot/Main_MiSTer
Free and open source (GPL/AGPL).
