Since the launch of the Nintendo Channel for the Wii earlier this year, Nintendo has been providing a DS Download Service with demos of released and upcoming DS games. Wii owners can boot up the DS Download Service through the Nintendo Channel and download various playable demos directly to their Nintendo DS, using the Download Play option. It works in the same way as the in-store download stations. The third-party games get updated every week and we've got info on this week's batch to let you know a little more about what you're getting.
