NES and SNES Emulator request

I would like to request 2 emulators if I may that I think many people would find useful. They seem to have been mentioned in previous threads, but it doesn't appear as though anything ever came of them. I know nothing of how to make an app portable, so I can't be of much help there as far as this request goes. I'm not sure if they are "Just Works" programs, but if they are it would be nice to have them integrate into the portable apps launcher.
