# Capybara: reconstructing Sonix hardware for Tamagotchi Paradise firmware

> Capybara reconstructs the Sonix SNC73410 hardware environment needed to run Tamagotchi Paradise factory firmware on a computer. Its Rust emulator implements an ARMv7-M core and peripherals modeled from measurement, imports a user-owned 16 MB flash dump and derives the dump's decryption value before booting it.
