I recently got a Wii U thinking it was a homebrew master system and plug-and-play-simple. Knowing it's so complex, I researched as much as I could but am stumped on a few things. I'm trying to see if I only need to get a GC adapter or if I'll need more. Feel free to lock or redirect as relevant. 1. Is playing gamecube games multiplayer with 4 gamecube controllers supported on Wii U homebrew like Nintendont? (with the adapter, beyond the Wii U Pad 1st player input hack) 2. Is there homebrew gamecube multiplayer support with other controllers? (like 4 classics or 4 wii u pros) 3. Do virtual console games or retro emulator games have 1 or more gamecube controllers supported? 4. Have Wii U games been hacked for universal GC controller support?
