Twitter user Master Mewking was among the first to discover the new controller support. It's not foolproof as yet, with many users reporting that it takes multiple attempts to pair a pad - perhaps explaining why Nintendo hasn't publicised the change.The process is, on paper, fairly simple: Make sure your Switch is set to accept wired controllers, plug the adapter in, plug the controller in, choose to pair controllers, then press L and R. Up to four GameCube controllers can be used simultaneously.All Switch games appear to be compatible with GameCube controllers, although there is a caveat - you won't be able to use any ZL commands, or the Home button.Naturally, the addition's led to speculation that we'll see the long-rumoured release of GameCube Virtual Console titles , or a new version of the famously GameCube pad-friendly Smash Bros.The 4.0.0 update also added save transfers and 30-second video capture for select games.
