Get the mayflash one instead, it works really well and has a switch on it to use it on PC via USB HID so emulators other than dolphin can use it. The cord is also decently longer than the official adapter also.
Aight, thanks for the advice
Anyone else feel like the post should be edited to reflect the reported issues with some third party Gamecube adapters? I mean, it says ALL third party Gamecube adapters work, even though the Nexilux adapter obviously doesn't from my experience. Don't want anyone else to have to learn the hard way I suppose.
