WHat is the best DS emulator and how do I set it up so it will work properly?

My DS broke recently, and I found out there are several DS emulators out there, but, I dont know what one to use or how to use it... please help?

no$gba. Search the NDS Trading Station for no$gba 2.6a, which is the latest version. Once done, get your ROMs and drag them onto the no$gba .exe. They should run. Then just mess around with the settings to get better performance etc. Have fun! :)

I had no$gba. It didn't work for some reason, I don't know why but i now use ideas and it works I want to know if I download the newer version of no$gba if i can keep my saved games ??? ???

You should be able to because they both keep the .sav format.
