I suggested that several times alreadyThere's a third one. Someone with the right coding skill should look at Twilight Hack (or Indiana Pwns, Yu Gi Owned etc.) source code and try to port it Xenoblade, Pandora Tower or Muramasa, i.e. a game available on eShop with Classic Controller support. Said game would act as an Homebrew loader (with CC support), like Twilight Princess in the old Wii days.
I argue this method is easier, as we don't touch the cafe2wii part at all. We are operating entirely with Wii code and hardware. But I'm not a developer, so maybe this idea is bullshit What do you think, @pedro702 ?
