I do have an original NES. Two infact. Front and top loader styles. The problem is that the Front Loader system crashes after a few minutes of gameplay, with any game. The Top Loader only has RF output, which I do not have the ability to capture or convert at this time. Also the picture on the Top Loader model is not as good as the Front Loader. Has something to do with scanlines as I understand it.
I'll be picking up another front loader NES when I can, probably going to hit up some retro stores on black friday. Also getting other adaptors and accessories I'll need to get everything streaming right.
I do have a game genie, but I had modified the case to work on the Top Loader, and it will probably get stuck inside the Front Loader as a result now.
