What runs here. Each game is an Atari 2600 emulated in a worker. Its brain is born in a second worker with a fixed seed: a Cadence 0.70.0 System 1 brain, 7,056 sensory neurons for the 84 × 84 screen, an association cortex with a working trace, a motor cortex with one neuron per action, a critic and an associative memory, 456,000 synapses that settle together for every answer. It watches a scripted teacher play (Freeway: always up; Atlantis: always fire) and takes each watched screen as a lesson. Once its own answers agree with the teacher's often enough and it has watched one whole game, it takes the controls, and from then on it learns from the reward of its own actions. The brain is a JavaScript version of Brain.compose, checked against the Python library on recorded fixtures; the emulator is the 6502.ts core. Source, parity harness and receipts.
