I feel this kind of relates to Dolphin but there is no other place to post it so I'm making the thread here. I made an issue report on Bizhawk's Github page about support for Nintendo's Official Gamecube Adapter by implementing it the same way Dolphin detects it. Eventually I was told to ask around to see if anyone would tackle the issue. I don't know if anyone would be interested in doing this and I don't have anything to give to anyone so if no one wants to do this that is fine.
