# YBX ESP32 System Emulator: reconstructing e-ink reader hardware in QEMU

> YBX ESP32 System Emulator reconstructs selected hardware behavior so original ESP32-S3 and ESP32-C3 e-ink reader firmware can run in QEMU. Its patches and host tools model display and touch paths, capture panel framebuffers, and record boot, peripheral and navigation experiments for YBX X4 Pro and CrossPoint images.
