If anyone cares, or is interested, there's a fan-made GameCube online service called "The Warp Pipe Project". Right now, it only supports "Mario Kart Double Dash", "1080 Avalanche", and "Kirby's Air Ride", though. The address for the actual site is
http://www.warppipe.com. And to cover my ass, I saw nothing of this or anything like it in previous posts.
