Stuffing an NES into an FPGA


Image IPB


When the developer of the µTorrent torrent client and the ScummVM LucasArts adventure game interpreter gets bored, something cool is bound to happen. Luckily for us, [Ludde] was a bit listless over Christmas, and with more time than energy to burn, implemented a Nintendo Entertainment System on an FPGA dev board.
The NES was powered by a Ricoh 2A03 CPU, a chip nearly identical to the 6502 found in the Commodore 64s and Apple IIs of the early 1980s. There are a few differences between the two, though: the NES CPU includes an Audio Processing Unit on the chip and is connected to a very cool Picture Processing unit elsewhere on the NES. [Ludde] put all these chips in his Spartan-6 FPGA with a lot of Verilog code.
The rest of the system ?? the RAM, display output, and controller input comes from the peripherals attached to the FPGA dev board. [Ludde]??s specific board didn??t have a good digital to analog converter, so the composite output was traded for a VGA output. It??s not a completely accurate color pallet, but it??s still an amazing piece of work for someone who was simply bored.
