Run DOOM on an NES by embedding a Raspberry Pi in the cartridge

Hi all, I just released my project - https://github.com/rasteri/PiPU

It's a method of using a Raspberry Pi as a graphics accelerator for the NES. It uses Cypress Semiconductor's FX2LP High-speed USB controller to hijack the NES' graphics memory bus, and inject video data directly into the NES' picture processing unit.

In the github there's the graphics translation code, as well as the firmware for the FX2LP and the 6502 code for the NES' CPU.

Here's a video going into more detail :

Congratulations!!! Very cool project and nicely done.
Also, let me tell you that I am impressed by your comments during the video. Fast but not too fast and very clear and understandable.
Just one question. How long did it take you from initial idea to finished project?

Regards,
Vitor

I got the idea about two years ago, but I took a long break in between. It was one of these projects where it was bubbling away in the background for a long time, and eventually I'd made so much progress that abandoning it would be a bigger waste of time than just finishing it, haha.
