They should make a "DS Player" for the Wii like the Game Boy Player. Then you could play NSMB on Wii (possibly with a GC controller).
Then again, the fact that the DS has two screens would make it rather...complicated.
I'd really like playing M&L: Partners in Time on the big screen though...I always liked putting M&L: Superstar Saga in the GB Player, plugging in two controllers, and playing co-op with my friends.
