To avoid the risk of being lost in the vast sea of the WOYM thread, this is a thread for talking about various things Nintendo related.
Anyway... I looked online yesterday to see about the WiiU's ability to play Wii titles, as well as whether Gamecube titles are downloadable from the WiiU eShop, and was met with disappoint on two fronts.
First, if you want to transfer Wii VC purchases to WiiU, you won't be using the WiiU eShop, but rather the Wii Shop Channel on the WiiU's Wii emulator. This means your Wii VC games don't support the WiiU game pad (since the Wii emulator doesn't) as well your Wii VC title are eternally separated from WiiU eShop titles.
Second, the WiiU doesn't have a Gamecube controller port, which means it doesn't support Gamecube titles AT ALL. This despite the Wii supporting many of every past Nintendo console's games (via emulation).
The Wii used an emulator to play Gamecube games, but it was completely transparent. It seems that Nintendo really have half-assed their newest console in more ways than crappy marketing.
