# BetterJoyForCemu v3.0b Allows the Nintendo Switch Pro Controller to be used with the [Cemu Emulator](http://cemu.info/) and [Cemuhook](https://sshnuke.net/cemuhook/). __Note that this program allows the Pro Controller and Joycons to be used system-wide without installation of Cemu - just follow the *How to Use* instructions until point 3__ # Changelog ### v3 * Added XInput Support using ViGEm. * No longer need to use "Also use for axes/buttons" * System-wide compatibility (use your Joycons with Steam, or something) * Requires ViGEm driver (provided in release) * Rumble support * Ability to rebind keys * __v3a__ * Added more app settings * Ability to disable rumble * Option to swap A-B and X-Y (on request of Paul) * CemuHook gets fed correct data about the kind of connection the controller is on * __v3b__ * Fixed button swapping not working on Joycons ### v2 * Added Joycon support * Exposes two CemuHook controllers - both have all the buttons, selecting one or the other will just pick whether to use the right or left Joycon for the motion controls * Make sure both controllers are connected beforehand * Further gyro fixes * Code cleanup ### v1.51 * Added USB support * Eliminated gyro shaking * Improved bluetooth support * It's no longer necessary to completely remove and then reconnect the pro controller from your bluetooth devices when you turn it off * Pro controller reconnects to computer normally now * Added 32-bit release (untested) * Cleaned up code * __v1.51__ * More gyro fixes (runs at max UDP now - as precise as one can get) * Especially noticeable in USB mode ### v1 * Initial release # How to use 1. Connect pro controller via bluetooth/usb 1. Install ViGEm drivers 1. Run *! Install ViGEm Driver (Run as Admin).bat* 1. Run BetterJoyForCemu.exe 1. If the controller recongised, the first LED should light up. 1. If not, see the __Problems__ section. 1. Start Cemu and ensure CemuHook has the controller selected. 1. If using Joycons, CemuHook will detect two controllers - each will give all buttons, but choosing one over the other just chooses preference for which hand to use for gyro controls. 1. Go into *Input Settings*, choose XInput as a source and assign buttons normally. 1. If you don't want to do this for some reason, just have one input profile set up with *Wii U Gamepad* as the controller and enable "Also use for buttons/axes" under *GamePad motion source*. **This is no longer required as of version 3** 1. Turn rumble up to 70-80% if you want rumble. 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. * As of version 3, you can use the pro controller and Joycons as normal xbox controllers on your PC - try it with Steam! # App Settings Feel free to edit *BetterJoyForCemu.exe.config* before running the program to configure it to your liking. Current settings are: * IP address of CemuHook motion server *(default: 127.0.0.1)* * Port number of CemuHook motion server *(default: 26760)* * Rumble Period of motor in ms *(default: 100)* * Frequency of low rumble in Hz *(default: 160)* * Frequency of high rumble in Hz *(default: 320)* * Rumble - en/disables rumble *(default: true)* * Swap buttons *(default: false)* * Swaps the A-B and X-Y buttons to mimick the Xbox layout by button name, rather than physical layout # Problems __Make sure you installed the ViGEm drivers!!__ 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. If you get weird lag/stuttering - restart your computer; or try running the program multiple times, closing it properly (by pressing enter) each time. If something isn't working but it looks like it should be - try running the program as administrator. __Note that for Joycons to work properly, you need a decent Bluetooth adapter that is comfortable with handling 3/4 connections at a time.__ __If while using a pro controller in USB mode, the program hangs on *Using USB*, just close the console window and open it again.__ ## 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. ## CemuHook not recognising the controller Make sure that CemuHook settings are at their default state, which are - ``` serverIP = 127.0.0.1 serverPort = 26761 ``` Feel free to open a new issue if you have any comments or questions. # Connecting and Disconnecting the Controller ## Bluetooth Mode Hold down the small button on the top of the controller for 5 seconds - this puts the controller into broadcasting mode. Search for it in your bluetooth settings and pair normally. To disconnect the controller - press down the button once. To reconnect - press any button on your controller. ## USB Mode Plug the controller into your computer. ## How to properly disconnect the controller ### Windows 10 1. Go into "Bluetooth and other devices settings" 1. Under the first category "Mouse, keyboard, & pen", there should be the pro controller. 1. Click on it and a "Remove" button will be revealed. 1. Press the "Remove" button # Acknowledgements A massive thanks goes out to [rajkosto](https://github.com/rajkosto/) for putting up with 17 emails and replying very quickly to my silly queries. The UDP server is also mostly taken from his [ScpToolkit](https://github.com/rajkosto/ScpToolkit) repo. Also I am very grateful to [mfosse](https://github.com/mfosse/JoyCon-Driver) for pointing me in the right direction and to [Looking-Glass](https://github.com/Looking-Glass/JoyconLib) without whom I would not be able to figure anything out. (being honest here - the joycon code is his) Many thanks to [nefarius](https://github.com/nefarius/ViGEm) for his ViGEm project! Apologies and appreciation go out to [epigramx](https://github.com/epigramx), creator of *WiimoteHook*, for giving me the driver idea and for letting me keep using his installation batch script even though I took it without permission. A last thanks goes out to [dekuNukem](https://github.com/dekuNukem/Nintendo_Switch_Reverse_Engineering) for his documentation, especially on the SPI calibration data and the IMU sensor notes!
