A Atari 2600 cloned into a FPGA called the A2601

Atari 2600 recreated in an FPGA
Another old system in FPGA form. As always nice :) With the falling costs of FPGAs and there dev. kits there seems to be a rise in these projects which is a good thing. Last few attempts I seen at a Atari 2600 failed due the system having some kind of weird video/cpu timing but they was hardware based clones. Anyhow here it is :p

Behold [Retromaster's] field programmable gate array implementation of an Atari 2600. The processor and video chip have both been built in the 100,000 gate Spartan-3E FPGA, with connectors for audio, video, and a Sega controller. The output signals are generated using two DACs made from R-2R resistor ladders, much like the project we saw in August. [Retromaster] included functionality for the system switches (difficulty and select) in the controller itself. There is VHDL code and board details available if you want to make one of your own.
