DS Emulator for "New Super Mario Bros."

In Emulators / NES ROMs

I don't know if this is the right place since it is an NES forum, but I need a Nintendo DS emulator that can play "New Super Mario Bros." and somehow the ones I downloaded don't work. (I hope the NES ROM is a good one. Unfortuantely there is no Good Tool yet to check it.)

DS emulation is young still. I'd imagine that a game as new as New SMB isn't going to run yet. Are there any DS emus that run commercial NES ROMs right now?

Several months ago I was playing around with one that booted Meteos, and a few months ago I had one that booted the Japanese version of FFIII. It was very glitchy, and not really playable, but it did work.
