@Valmond sooo sorry for the late reply, but last couple of days where crazy

The badge is based on ESP32-S3, inspired by the Walkman and runs a fork of Tactility made specifically for the RomHack.
It can play music via a small speaker, or headphones, it runs Doom (and more) via retro-go, it has a IRC client.
It is equipped with an NFC reader that was used during the camp for a trivia game, where players had to go around to find hidden NFC tags, scan them, answer a question and get points.
