I had to sign up just to answer this question. Yes, there is a fully functional emulator for the DS. It's called DrasTic and it is available on android devices. You can get it at the Google Playstore for around 10 or 15 US dollars. I bring this up because of the DS touchscreen. Unless you have a PC or laptop with touchscreen functionality, I can imagine it would be fairly frustrating to play games that require touchscreen functionality in some form or another. That said, Tablets are inexpensive and most people have pretty decent Android phones nowadays, so that should not be an issue for most. Hope this helps.
