Nintendo has given players the ability to change the button layout of Joy-Cons and Pro Controllers. In the latest update
The newest Switch update, 10.0.0, brought a ton of great features to the console, including the ability to transfer downloaded content back and forth between the system memory and a removable SD card. More importantly, though, Nintendo has given players the ability to change the button layout of Joy-Cons and Pro Controllers. This is a useful feature for players that may have trouble using the controllers as intended, and will undoubtedly open the doors for many people to play games they otherwise would have never been able to.
Even though some games allow button remapping, not all of them do, and a system-wide feature like this means that players can create a layout that works best for them and then use it for every game they play. The Switch update will allow players to create up to 5 unique layouts for each Joy-Con and/or Pro Controller they use, so whether you share your Switch or just need layouts for different games, there should be enough profiles available.
The interface for remapping the buttons is simple to use. From the System Settings menu scroll down the list until you see Controllers and Sensors. From there, the second option is Change Button Mapping. On this menu, select the Joy-Con or Pro Controller you want to edit, select change, and select the button, trigger, or control stick you wish to change.
Every button is an option, including the buttons from the opposite Joy-Con. You can even disable any button if you need to. You can then save your layout and edit it anytime. If you have a layout saved to the SD card, you can load it in and save the time it would take to recreate it.
