Can nes roms play on gens?

[Genome]

im sure there is a way to do it though. i remember an article i read once where the creator of sonic the hedgehog said he first started development on it when he was playing around with his genesis dev kit and got his super mario brothers cart to play on it.

Why? There are plenty of good NES emus out there...
I don't see why people want as much systems as possible in one emu. I'd rather go for an accurate emulator that'll let you play just one system.

It would be nice if there was one emulator that played every game there is.

The same reason people want a CD player that will play MP3s, and a DVD player that will play DVD's, VCD's, actual video files, MP3's etc.. Convenience, and its not a worthless idea.

MAME is the perfect example of emulating tons of different hardware platforms accurately. It's not that it can't be done, it's that people are either disinteresting in the idea from a development standpoint (too much work), or that the multiple machine emulators out there already, like MESS, just develop slowly over time.
