Could you build this?

No Building an ESP32-C3 hardware emulator capable of running unmodified compiled ESP-IDF binaries in WebAssembly requires low-level RISC-V CPU emulation and peripheral hardware modeling.

What it would actually take: The architecture requires a full RISC-V RV32IMC instruction set emulator, MMU/memory bus modeling, and register-accurate peripheral emulation (UART, Timers, SPI, Wi-Fi MAC/PHY stubs, FreeRTOS ticks) compiled to WebAssembly via Emscripten or Rust. The most difficult challenge is cycle-accurate instruction dispatch and reverse-engineering proprietary Espressif hardware registers to satisfy unmodified ESP-IDF bootloaders and kernel drivers. This requires specialized low-level systems engineering, CPU virtualization, and embedded hardware expertise.
