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
