No Decent Emulator - yet Plenty of Roms

Hey, all.All over the Internet (especially here at RomUlation) I see NDS Roms. Yet, I've only been able to find 4-5 Emulators for NDS. ???And, out of those, only ONE worked with any sort of success: No$gba-w. But, I could only get the 'Prologue' of each game to play well. Once the ROM got to any actually gameplay, playback was so choppy that it was impossible to play. >:(So, I figure there HAS to be decent Emulators if there are so many ROMs.Any suggestions on Emulators, and/or places to find them? thanks! :D(I've tried no$gba-w, iDeaS, NDSemu, and DualiS.)

you figure wrong, unfortunately. there are no 'decent' emulators yet; they are all still work in progress. No$GBA is the best so far, but only some games work, even less work and are playable. All are slow.

What people do is they play the ROMs on their actual NDS using a flash cart.
Much like you can burn a playstation ISO if you have a chipped playstation.
