Hello er_name_not_found, Thank you so much for the information. And you havesome good points "Why". Well my answer is why not. I always wanted to do more with the NES system. Make a glorified Serial monitor Or a text terminal and even maybe to talk to another NES system. Who knows. The limit to me is yes understanding the pinout and programming which is not my strong point. I can do the hardware that is my thing. But programming is well something else.
This will help me big time.Thank you I will keep this up until i figure out how to get this to work or fail. But it is something I always wanted to do.
p.s.s I did see the cartridge working on the arduino for dumping the rom. But that is all.
Joseph
