I heard you can play ds games on the wii, is that true and if so, how the heck do you do it??
You can play GameCube games on the Wii, but I've never heard of playing DS games on the Wii. For some games you can use the DS like a controller, maybe that is what you heard? But you can't play DS games on the Wii. Just Cube.
The Wii system supports wireless connectivity with the Nintendo DS without any additional accessories. This connectivity allows the player to use the Nintendo DS microphone and touchscreen as inputs for Wii games. The first example Nintendo has given of a game using Nintendo DS-Wii connectivity is that of Pokémon Battle Revolution. Players with either the Pokémon Diamond or Pearl Nintendo DS games are able to play battles using their Nintendo DS as a controller. It has also been announced that the Nintendo DS will be able to play game demos downloaded from the console, which they would receive from Nintendo, similar to a DS Download Station. The console is also able to expand Nintendo DS games. This type of connection has been released only in Japan, in the form of the Everybody's Nintendo Channel.
