I would like to know if I could find a way to bind a combo like the "hadouken" (Hadouken is a combination of movement of a joystick: down, down-right, right + button ) of street fighter to make an easter egg on my emulationstation of retropie. I've a .sh script which inside I've the instruction:
mpg123 -Z /home/pi/bgm/*.mp3 >/dev/null 2>&1 &
I use that to play random mp3 from bgm folder, but i would like exactly use "hadouken" combination to launch/stop that .sh. Any idea or suggestion?
