How to Set Up a Real GameCube Controller in Dolphinįirst, if you’re using a non-official Adapter that offers a toggle between “Wii U” and “PC” modes, switch it to “Wii U.” Dolphin has native support for the GameCube Controller Adapter once you have installed the proper driver, so feel free to ignore the PC mode unless you wish to use the controller in other applications. You can use your original sensor bar plugged into a running Wii, a battery-powered Wireless sensor bar, or a USB sensor bar.

If the adapter is wired and works with the Switch or Wii U, chances are it’ll work here, too. We recommend either Nintendo’s official adapter or the MayFlash Adapter for the best results. Additionally, you might find that some controllers that look like GC pads but are actually Switch Pro Controllers. While unofficial options work, they are much worse in build quality. An official Nintendo GameCube Controller.It's not really about reducing the latency like the OP says, it's about making the polling more stable so that your inputs are read correctly.To use a real Nintendo GameCube controller with Dolphin, here’s what you’ll need: I only tested it for a bit in-game because it's late, but my movement on Slippi feels significantly closer to CRT. I could be crazy, but plugging in more controllers seems to reduce the frequency of dips back down to 500hz. The google doc said that plugging in an idle controller would only help on the official adapter, but it has similar effects on the Mayflash in my experience. I updated the firmware on my Mayflash to V.05 and it now shows an average of ~1000hz but occasionally dips back down to ~500hz.īefore I updated the firmware, if I plugged in a second controller, then my polling rate raised to ~1000hz on average, while still occasionally dipping back down to ~500hz.

I'm on a Mayflash 4-port and I was getting ~500hz as my maximum polling rate (still a huge improvement tbh) despite following the instructions.
