RootedCON 2026 Pacman Badge
Spanish ESP32 Pacman badge reconstructed from community reversals
A Spanish RootedCON 2026 official Pacman Badge reconstructed from multiple community reversing repositories as an ESP32-D0WD-V3 board with a 1.77-inch ST7735 128x160 display, a directional pad, buttons, and a native quiz-server CTF protocol, distributed at the March 5-7, 2026 sixteenth edition at Kinepolis Madrid.

SourceWhy It Mattered
It adds a major Spanish security-conference badge to the compendium from convergent community hardware reversals, while keeping the official-status, designer, and production claims conservative because no official RootedCON badge repository or confirmation was recovered.
Hardware
Community reversing repositories converge on an ESP32-D0WD-V3 microcontroller, a 1.77-inch ST7735 128x160 TFT display, a directional pad, and additional buttons. The original official badge firmware shipped a custom Pacman-themed firmware, and the r4venOS community replacement documents WiFi scanner, evil-twin detection, deauth, and crypto utilities on the same ESP32 hardware. No official schematic, PCB, BOM, or production file has been recovered.
Software & Apps
Community repositories document the badge as a PlatformIO ESP32 target and reverse the original Pacman firmware's native quiz-server CTF protocol, including arcade mode, Marauder integration, and server emulation. No official RootedCON firmware or hardware repository was recovered in this pass, so the record treats the firmware trail as community-sourced rather than officially published.
Lore
RootedCON is a long-running Spanish cybersecurity conference, and the 2026 sixteenth edition ran March 5-7 at Kinepolis in Madrid. Multiple independent attendees reversed the official Pacman Badge and published firmware, CTF, and repurposing repositories, but no official RootedCON badge repository or named badge designer was recovered, so the official-status and designer attributions stay inferential.

missing rights-cleared image
note
No RootedCON 2026 Pacman Badge image is published because no reusable original badge photo or official upstream raster render with source URL, license or permission basis, attribution, and processing notes has been recovered.
The Spanish record remains source-backed and image-free rather than copying community repository diagrams, screenshots, social media, placeholders, or generated approximations.

official-status and archive gap
note
The Pacman Badge hardware and CTF protocol are reconstructed from community reversing repositories, but no official RootedCON badge repository, official confirmation, named designer, schematic, PCB, BOM, or production file was recovered in this pass.
The record treats the badge as the official RootedCON 2026 badge on the strength of convergent community reversals, while keeping the official-status, designer, and production claims conservative until official sources appear.
