No firmware, no microcode? It's all completely hard-wired?
(Genuine question, I've no idea what chips it uses or anything - was never rich enough to have a game console until I started work myself.)

Nope! The system does include a CIC lockout chip, but emulators pretend it doesn't exist. The CPU immediately begins executing game code at power on. There is no BIOS or operating system, and indeed no fixed ROM inside the console at all.
