Look at the early models of the playstation 3. It was backward compatible with both ps1 and ps2 games. The Wii U should be like that too. It doesn't need the gamecube controller ports or the memory cards. They could have made the wii u pro controller work with the gamecube games. The games could save data internally to eliminate memory cards. And to transfer old save data, nintendo could have made an adaptor to plug gc memory cards into (I think there's one like that for the PS3). And think about the possibilities if they had made the gamecube games work with the wii u gamepad. We'd essentially have a handheld gamecube! Man this would have been so awesome. Why didn't nintendo do it? Also do you guys think the Wii U will able to emulate gamecube games after it gets hacked?
