Why won the wii play Gamecube games online?
Games that were designed to use the Broadband Adapter or Modem Adapter (the two online games and the roughly half-dozen LAN-capable games) had to be written with basically the drivers for those devices built into them. As a result, when those games try to communicate with another system, they look for those devices first. Since the Wii does not contain either of them, the game then refuses to continue with the online/LAN section.
