joycon-cemuhook

Support for cemuhook's UDP protocol for joycond devices for use with emulators like Dolphin, Cemu, Citra, Yuzu, etc.

Based on https://github.com/joaorb64/joycond-cemuhook, a lot of heavy lifting is done in joycon and pad-motion crates, mostly just glue code here.

Work in progress, TODO

• controller initialization, still need to run joycond-cemuhook.py to let controller join a slot
• multiple controllers support, only one controller is supported now
• hotplugging, it only detects controller when application start
• requires root support, most likely on joy side
• print out some useful debugging information like device connect/disconnect

How to use

• Install dkms-hid-nintendo (if your kernel doesn't include the hid_nintendo driver)
  • hid_nintendo did not work for me since it kernel panics DanielOgorchock/linux#36
• Install the joycond userspace driver
• As for now, still need to run joycond-cemuhook to let controller join slot
• Clone this repository, git clone https://github.com/pickfire/joycon-cemuhook
• Navigate into the directory with cd joycon-cemuhook/
• Build with cargo build --release
• Run with sudo target/release/joycon-cemuhook

From now on, you'll only need to run joycon-cemuhook from a terminal on its directory.

• Connect your Nintendo Switch controllers and assign them as intended (using the respective L+R)
• Open a compatible emulator and enable cemuhook UDP motion input
