This Python version uses the same 6502 circuit node names and ids as our web-based javascript version but has no polygon geometry. It includes our full netlist model of the Atari TIA and a simple emulation of the PIA, aka RIOT, and program ROM. Leave it running long enough, and it'll render frames from classic games.

The simulation provides a cycle-accurate picture of what the console is doing based on the physical parts of its microchips.
