nintendo ds emulator?

could someone direct me to an emulator that will run Pokemon Diamond?

its a called a nintendo DS, so far the only emulator that can run almost every NDS rom is the no$GBA but it doesnt feature a proper save method so its useless as of now. If you really want to play it, buy a NDS/NDSL and get a flash card for it.

;DThere is actually NO$GBA v2.6a which is currently the best nds emu. It can emulate thousands of roms. All you have to do is configure the proper save type and it will save.

no$gba2.6a has an "auto" function that automatically sets which save type will be best for each NDS ROM you wanna play.

I've never had any problem with any saves with my no$gba2.6a. Always works great just the sound is a little gargoly sometimes so I just turn it down real low.
