A Commodore 64 simulator where you can pull a chip out and watch the screen break. antirez’s c64-hw-simulator models the motherboard pin by pin. The corrupted display is computed from the circuit, rather than selected from a list of known failures. It’s built for learning and repair clues, not fast gaming. Matching a real fault’s symptoms is a clue, not a diagnosis. Retro-computing people: which fault would you try first? https://github.com/antirez/c64-hw-simulator
