RootedCON 2026 Pacman Badge
Spanish ESP32 PACMAN CTF badge with project-builder and community-reversal evidence
RootedCON 2026's PACMAN-themed attendee CTF badge is documented by both community reversals and a first-hand TechFrontiers project-builder write-up. David Melendez Cano reports original colored Ghost boards that attendees could choose, an ESP32-WROOM-32 platform, ESP-NOW game-server interaction, per-badge NVS identity/key material, and digitally signed questions and answers. Community reversals independently identify an ESP32-D0WD-V3, 1.77-inch ST7735 128x160 display, directional controls, and native quiz-server CTF protocol for the March 5-7 sixteenth edition at Kinepolis Madrid.
