I like to play Console style RPG games on emulators. I might have liked it better to play them on consoles itself. But those older consoles are no longer available, and neither are games. At least, not that I have seen.
Btw, I have played and completed Final Fantasy V, and Breath of Fire on my emulator (Snes9x) what about you?
Emulators are a great way to allow us to play games of the older consoles, which are no longer available. In that sense, emulators will never be hot. Hottest things are those which haven't been built yet. Because you can make all sorts of tall claims about how cool it will be and how it will blow every thing away. Reality is often different, but you don't know that yet, since the new product/game hasn't been released still.
Doom3 was hot before it came out, HL2 was hot before it was released. Longhorn is hot now, Ps3 is hot etc.
