Found this while looking for ESP32/QEMU browser implementations. The multi-board sync between different architectures (AVR vs Xtensa) is what caught my eye. Pretty impressive use of WebAssembly

Creator here! Just saw this was posted. I've been working on the 2.0 release to move beyond simple AVR emulation. Integrating QEMU for the ESP32 and Pi 3 (Linux) was a massive challenge, especially maintaining sync between the different emulators in a single browser tab.
