Hi Guys,
well recently I remove a little dust on one of my pi3b and purchase the Kintaro Sueper Kuma 9000 case, Sadly the board didn't work with Recalbox 9.0, so after a little research I found the original script but no success.

I make a few tweaks in the code and make it work.
all buttons and fan control work great

you can download the script on GitHub
