# I find that waydroid from arch official repo performs poorly (4th March 2025). So I recommend and use waydroid-git
paru -S waydroid-git
sudo waydroid init -s GAPPS

# waydroid-extras: https://aur.archlinux.org/waydroid-script-git.git
# For amd use libndk
sudo waydroid-extras install libndk widevine magisk

Emulate Joystick

git clone https://github.com/iosonofabio/virtual_gamepad
paru -S python-uinput python-pynput

# For script to work load uinput
sudo modprobe uinput
# Load module on boot
sudo echo uinput >> /etc/modules-load.d/uinput.conf

# To use script without sudo:
sudo groupadd uinput
sudo usermod -aG uinput "$USER"
sudo chmod g+rw /dev/uinput
sudo chgrp uinput /dev/uinput
sudo usermod -aG input "$USER"

For permissions (uinput group owning /dev/uinput) to persist across reboot:

/etc/udev/rules.d/99-uinput.rules
KERNEL=="uinput", GROUP="uinput", MODE="0660"

taunts with xdotool and xbindkeys

I don't think there's a way to get taunts working just with joystick. You need to make use of the mouse and screen. I did this using xdotool and xbindkeys.

~/.xbindkeysrc
"~/bin/taunts.sh z"
    m:0x0 + c:52
    z

"~/bin/taunts.sh x"
    m:0x0 + c:53
    x

"~/bin/taunts.sh c"
    m:0x0 + c:54
    c

"~/bin/taunts.sh v"
    m:0x0 + c:55
    v
~/bin/taunts.sh
#!/bin/bash

if [[ $1 == "z" ]];
then
  xdotool mousemove 3326 937
  xdotool mousedown 1
  xdotool mousemove 3285 921
  sleep 0.1
  xdotool mouseup 1
elif [[ $1 == "x" ]];
then
  xdotool mousemove 3326 937
  xdotool mousedown 1
  xdotool mousemove 3326 852
  sleep 0.1
  xdotool mouseup 1
elif [[ $1 == "c" ]];
then
  xdotool mousemove 3326 937
  xdotool mousedown 1
  xdotool mousemove 3435 921
  sleep 0.1
  xdotool mouseup 1
elif [[ $1 == "v" ]];
then
  xdotool mousemove 3326 937
  xdotool mousedown 1
  xdotool mousemove 3285 1001
  sleep 0.1
  xdotool mouseup 1
fi

I found the appropriate location for mouse using xdotool getmouselocation --shell.

I run xbindkeys with xbindkeys -n so that I simply ctrl-c the script to revert keybindings.

Weird waydroid issues

https://github.com/waydroid/waydroid/issues/1576

Solved this by first setting up sound.
