An idea about the use of rumbling controllers in old games

[Le gars sympa]

Hi everyone,

First of all, thank you for all the great work done here, I'm really enjoying my recalbox and I just can't wait for the 4.1 this evening.

I'm using xbox one s bt controllers and it works great after fixing the bt service at startup in the custom.sh file. As most of my favorite games are 80's and 90'[censored]s, I was thinking about using the controller vibration thing with those games. Of course I know they have not been designed for this modern feature but... would'nt it be great for 2 players (or more) games to let players make rumble the controllers of their opponents using a trigger for example ? Can you imagine how Tetris, Street Fighter II or Super Mario Kart could be using this "shake my opponent" feature ? I have no idea about how to to this, I guess this could done by some kind of listener script at start up using the driver to do this... But at that time I'm stucked on it... Someone interested in that feature ? Is it just possible ?

Thx.
