# How to use
2018-03-05 08:16:48 +00:00
1. Make sure CEMU has at least one input profile set up already (so that CemuHook can feed data into it)
1. If you don't, go into _Input settings_ (under _Options_ ) on Cemu and set the first controller to be a Wii U Gamepad, you can leave the rest of the settings blank (or set the device to your keyboard)
2018-03-04 18:01:54 +00:00
1. Connect pro controller via bluetooth/usb
1. Run BetterJoyForCemu.exe
1. If the controller recongised, the first LED should light up.
2018-03-05 08:16:48 +00:00
1. If not, see the __Problems__ section.
2018-03-04 18:01:54 +00:00
1. Start Cemu and ensure CemuHook has the controller selected.
1. Enable "Also use for buttons/axes"
1. Please press enter in the console box once you're done with the program - closing it by clicking "x" does not stop the services correctly.

# Problems
If the controller does not work after restarting the exe too many times - shut down the exe, disconnect your pro controller and connect it again.
2018-02-27 22:34:33 +00:00
If you get weird lag/stuttering - restart your computer; or try running the program multiple times, closing it properly (by pressing enter) each time.

## No joycons detected
If using Bluetooth - see the "How to properly disconnect the controller" section and follow the steps listed there. Then, reconnect the controller.
If using USB - try unplugging the controller and then plugging it back in, making sure to let Windows set it up before launching the program.
## Getting stuck at "Using USB" or "Using factory.."
Close the program and then start it again. If it doesn't work, see the "No joycons detected" section and try that.
