Mayflash GameCube Controller Adapter for Wii U, PC USB and Switch, 4 Port [New Improved Version

I went from a bad player with a Pro Controller to a bad player with a GameCube controller 10/10

AlrightTested this product on the PC and Nintendo SwitchFor the PCPlayed several games with itPlayed Sonic Mania thru Steam and the game played just finePlayed Doom (by id Software, Bethesda Game Studios) thru steam and a bit awkward but I had to set up the buttons and controller settings but Doom 2016 I wouldn't recommend using this controllerPlayed 20XX thru steam and the game played just finePlayed Megaman 11 and the game played just fine, minor/rare problem with picking up a button input sometimesThe GameCube controller was responsive, no delays and no awkward dead zones. This was true for both an old Gamecube controller from many years ago and a new Gamecube controller (Smash Ultimate).Playing on the Nintendo SwitchPlayed Classic games, such as Super Mario Bros 3, and the game had an input delayPlayed Splatoon 2 and the game had an input delayPlayed Octopath Traveler and the game had an input delayPlayed Pokemon Quest and the game had an input delayPlayed Legend of Zelda BotW and the game had an input delayPlayed Super Mario Odyssey and the game had an input delayMind you I made sure to have the adapter on the Nintendo Switch mode and not the PC modeI also understand the Gamecube controller wasn't made for every game I tried above but the point was to see if any problems would occur and would reoccurThe PC seems to be fine but using on the Nintendo Switch that input delay is annoyingJust so you know for reference the delay is slightly less than 1 second but if you plan on using this for competitive play I would NOT recommend this productI won't be using this for Super Smash Bros Ultimate.

I bought this product so I could use my old Gamecube controllers on my Nintendo Switch (including the Wavebird Wireless Controller). It works exactly as advertised and the response time seems perfect as well. It's a great way to give your old controllers new life.If you're someone who's looking to get this for your Nintendo Switch like I was, just keep in mind that game functions that call for motion control won't work. That said, I have yet to come across a game for the Switch where motion controls are an absolute must in order to play. Mario Odyssey allows you to use motion controls more than any other game I've played, but it's still easily playable without ever using that function.Lastly, also keep in mind that you don't get to determine which buttons become what on a different controller than the Switch's. For example, the left shoulder button that allows you crouch, long jump, and backflip in Mario Odyssey became the Z button on my Gamecube controller (instead of the left bumper). So you may have issues in certain games where it's not nearly as intuitive as using the Switch's controller is. But to me, this is still completely acceptable---the convenience of being able to use my old controllers again far outweighs the very minor nuisance.

UPDATE: The adapter works with Nintendo Switch for Smash Bros Ultimate and as a replacement joy con for other games when no motion controls are needed.Using the adapter in Wii U mode, plug the black usb male plug into your switch hub while using the switch in tv mode. You can now use your gamecube controllers as you would any other controller on the switch. Tested with Rocket League, Astro Bears Party, Fortnite and more. I'm hoping this holds up in December with Smash Bros Ultimate. This sounds too good to be true but could definitely save hundreds on joy cons.Original Review:Not many reviews talk about the PC aspect, so I'll discuss that first.In PC mode, the controller is fully mappable as a normal joystick and supports rumble after quick installation of drivers by Mayflash's website. I have used this adapter with two versions of Project64 (with rumble support!!), SNES9x, and NEStopia: each program worked great with the controller. In Wii U mode, this works great with Dolphin, a GameCube/Wii emulator, once you follow the directions on the Dolphin website. Dolphin is preconfigured for rumble support and premapped input. Could not be happier with using this on my PC.On the Wii U, as long as it is in Wii U mode, it works right out of the box for Smash Bros Wii U ONLY with first party wired and third party wired/wireless controllers. Have not tested this with a Wavebird GC controller yet, as I do not have one. No input lag whatsoever, was able to easily perfect pivot even though I am not a top tier competitive player.This adapter has an amazing build, with hefty supports at each point where the cord ends. Third party controllers do not fit as snug as first party controllers into the ports, however this has caused no problems even when playing with 4 players on the PC. The switch from PC to Wii U mode is large and has the right amount of resistance so that it will not switch unintentionally but feels like it will last a long time.All being said, if you plan to ever use this on the PC, then this is a much better option than the official adapter as you can take advantage of Dolphins Wii U mode support while having many more options than Nintendo's adapter when in PC mode. For the Wii U only this adapter is equal with Nintendo's, so pick whichever works best for you with price vs collector value.EDIT: This does work with the Wavebird!!

A disclaimer: I only just received this product, so I am not making any statement about its reliability. Others reviews can, perhaps, attest to its longevity. I can simply confirm that, with the Nintendo Switch 4.0 update which allows GameCube controller support through the Wii U adapter, this device serves perfectly well as a replacement to the harder-to-find Nintendo-branded product.

Originally thought it didn’t work with switch.... that is until i realized i hadn’t changed the switch on the back of the adapter from PC mode to switch mode. Works flawlessly
