My site, NES FANZ uses a flash player which plays NES mp3's:

I use it in every main page like accessories, reviews and so on. I was wondering, would you guys were interested in using it for Famicom World?
It's something to consider. I don't mind the way we've got it set up right now, which is that the MIDIs are played using your computer's default player.
Oh yeah.
