I didnt wat to risk Ban, so i didnt Bump it.

Nestopia. No contest. I know some people are bound to disagree with me though.

I use FCE Ultra, and it runs no problem, but the input always resets itself, and it doesnt have lots of extra features(Not that its a problem)
I will try out nestopia.

I say stick with FCEU. Otherwise Nestopia might be good, but here'e a list of most of the NES emus out there: http://www.emulator-zone.com/doc.php/nes/

A long time ago I used to use NESticle, I think it was the best back then. Now I use NEStopia which has worked perfectly for me.

NESticle was "the best" (and I use the term very loosely) back in 1996-1997.

RockNESx for me, I'm a feature man and no other emu boasts as many features.
