DS Emulator for Wii?

[RiderLeangle]

Is there a DS Emulator that can be used with Homebrew Channel?

No, but there is a gba emu for the wii.

I know about VisualBoy Advance GX. I use it sometimes.

But I was wondering if a Wii emulator for DS existed, I guess it doesn't (someone should port No$GBA to Wii).
For Touch Screen I would think you would point the Wiimote where you want to touch.
