Recently found out about this very interesting and under recognized feature of using alternate controllers on Devolution. As far as I can tell you can use CC, CC Pro, WiiU Pro, PS3 controllers while playing gamecube backups. I'm confused about some of this though. Would a WiiU Pro only work on a WiiU in Wii/Gamecube mode or does this work on ANY Wii? Has anyone tried these alternate controllers and are they perfect 1:1 with no input lag? I'm very interested in some alternate controller use. Especially want to know if a WiiU Pro works on older Wiis and if there is no lag.
