I'm afraid I am dual > single all the way. The novelty of the dual screen saves it from the crippling reality that it's just a cabinet with a modified NES in it. Granted, RGB to an arcade monitor NES, but still...
I just can't bring myself to agree, I'd like to but I cant. Running the newer bios is completely retarded on a dual monitor too. Then all you have is a single monitor playchoice with a screen saver on top. Maybe I'll just put a fish tank up there or something...
