super gun on a big screen

How would I get the best picture avalable. I was planning on building a supergun but if not what should I plain on looking for. If I do build it myself what type of converter would be best. Its a 52 inch projection rca with hdtv/monitor. Help please.

I think a neobitz would be the best choice of video encoder for your application, but I've heard that the neogeo doesn't look as great on bigger tvs because of the actual output resolution being so small.
