A short write up is on my blog in case you're curious http://friendofmegaman.wordpress.com/20 … o-famicom/

I tried it on my breadboard first:

I didn't solder the caps to PPU and CPU as the tutorial required and didn't cut the trace to pin 21. I just wanted to test the concept and to my surprise the picture was pretty good. So called "jail bars" were barely noticeable.

I took GND and +5V directly from the voltage regulator (you can check 7805 datasheet to know which pin is which).

Now 3 things are left to do:
1. RCA sound mod
2. Finish the AV mod (add the caps)
3. Drill the holes in the housing shell for RCA jacks (not sure yet where to put them).

I wonder how hard would it be to preserve the RF signal also...

I've found two tutorials for the Famicom AV mod:

1. http://www.assemblergames.com/forums/sh … ur-Famicom
2. http://jpx72.detailne.sk/modd_files/fc/avmod.htm

And they are bit different. Question - who tried which and which works? (or perhaps both work?)

Thanks!
