I was doing some searching online about when/if Gamecube games would be added to the Wii U VC, Sounds like the system is capable, BUT it's not easy, and potentially they won't play back as well, with an emulator, compared to a disc. Then others believe Nintendo will continue to slowly rerelease the classics in HD. However this seems like it could take a while. Since they don't have time remake HD models of all their games, I came up with the idea of making A "Best of" Gamecube disc.
Super Mario Sunshine
(Hidden Game) Mario Party 5
Metroid Prime 2
(Hidden Game) Mario Party 6
Just think, both of these at 59.95.... I think they would sell well for very minimal work on Nintendo's End. Then if these were successful they could partner with Capcom and release some of their more mature Titles.
Hopefully something gives soon with N64/Gamecube games on the VC.
