Nanostray. That's really about it.....unless you count the Konami Classics compilation which has the old arcade Gradius.
Nanostray has some of the best graphics ever for the DS, BTW. Get this, it's scene release number 0080. Yeah, it's that old with graphics that sweet. Look it up.
The Konami Classics is scene release 0978.
Those are the only ones I can think of.....
There are a couple that are coming (God knows when though), Raid Over The River and Nanostray 2. I haven't heard any new info on those games in months though.
If their are any others someone may know about, I'd like to know too.
