Have your ever seen any of "Ben Hecks" portable console builds? Well if you haven't, he often uses these Chinese Famicom clone consoles. These cloned consoles are often times refered to as NOAC's, meaning NES On A Chip. They are called this because they are a fully functional Nintendo Entertainment System literally on one chip. The best part about the NOAC is that they include a 60 pin famicom game port, which in our case can easily be converted over to a 72 pin NES game port.
I originally got this idea from Kotomi (link below), and figured i would try to do the same thing. My plan was to use the original NES controllers, instead of the cheap super joy ones, which is what i believe Kotomi used. Kotomi's system also incorporated the original Famicom connector instead of the NES connector. In order to use the NES controllers, I would have to convert the NES controller's shift register data into the NOAC's controller chips. So... what better way to do it than with an Arduino!!!!
Step 1: Materials
1. Power Player Unit (or similar)
2. NES 72 pin connector
3. 2 NES controller ports
4. An NES game that will serve as the case
5. An atmega168 (arduino chip)
6. Texas Instrument TLC5940 (you can get these as samples from their site... their free)
7. Some basic parts such as switches, leds, along with a 7805 voltage regulator
8. PCB making stuff (I used the toner transfer method)
9. Basic knowledge of soldering and electronics
10. And most definitely a dremel tool with some bits and cut off discs
11. A multimeter is probably a good idea as well, because you will need it for troubleshooting
