Though rare, other devices may interfere with your Joy-Con signals. If nothing else is working, try turning off nearby wireless devices (one at a time) and see if the Joy-Con signal improves. Using it requires some gaming savvy, which, to be fair, you probably have if you’re attempting this in the first place. It’s an imperfect solution — not every game will work, no matter what you do. For now, we’ll have to wait for the homebrew community to come up with their own methods. BetterJoy is a piece of open source software specifically built to use the Switch Pro controller and joy-cons as generic XInput devices (and to make them easier to use with emulators).

Step 3: Hold the Sync button on the Joy-Cons, located between the SR and SL buttons, until the LED lights start flashing. And with that you're ready to game: your controller should show up and work in any game that an Xbox controller would. Unfortunately, the two Joy-Cons will be treated as separate controllers by default. That’s great for two-player games, but it makes them useless for playing anything complex, like a first-person shooter. There are some quirks to watch out for, such as when the pairing lights on the Joy-Cons won’t stop blinking. You can confirm that the controller is connected, however, by looking at your computer’s Bluetooth settings. If you see the error message below, move the controller around to ensure no other devices are interfering with the signal. Then try again.

Step 4: Look for the Joy-Con in your computer’s Bluetooth menu, and select the option to pair it with your device. For the Joy-Con to function properly when detached from the Switch, there must be an unobstructed line-of-sight between the Joy-Con and the Switch. Note: You only need to follow these steps if you're not using the Switch Pro Controller through Steam.

BetterJoy works by reading DirectInput commands as XInput commands, which is what most modern games support. Now that it's installed, your Switch Pro controller should behave like an Xbox 360 controller in most games.But first you have to launch BetterJoy for Cemu (the name of the executable) from its install folder. You're most of the way there! But because this is a DirectInput controller (like most gamepads other than the Xbox's), if you aren't using Steam's built-in controller interface, some games won't recognize the controller without some extra software.If all else fails, some users have reported being able to get warranty replacements, so that may be another option for you. Be sure to look into this before doing anything with your Joy-Con that would potentially void the warranty.

Most Macs and Windows PCs come with Bluetooth cards inside. Older computers might not have Bluetooth connectivity, which will limit your ability to play computer games with updated controllers. The Pro Controller should prove more viable for a wider range of games than the Joy-Cons, namely because it touts a more traditional layout, although it’s not compatible with everything. That’s due to the controller APIs in use; the Pro Controller apparently uses DirectInput, rather than the newer API XInput, making it incompatible with many newer games.Plug your Switch Pro controller into the PC with a USB cable. You should be able to use the USB-A to USB-C cable that came with the controller, or you can use a USB-C to USB-C cable, if your PC has the appropriate port. Within a few seconds, Windows 10 should pop up with a new connected device: Pro Controller.
