@staycade The old RPi.GPIO library no longer seems to work on the Raspberry Pi 5. Unfortunately, recalbox has not yet installed the alternative libraries and manual installation is not possible either. If the gpiozero library were available, you could use it to control the GPIOs and then the scripts would work again if you adapted them to the other library.

I've been trying for some time now to get a rotary encoder to work under Recalbox and Rpi5 to change the volume. Unfortunately, it always ends up failing because the current Recalbox version [9.2.3] for RPi5 only contains the old RPI.GPIO library, which no longer works with the Raspberry Pi 5. Since you can't install libraries under Recalbox yourself with apt-get, there is currently no way to really work with GPIOs under Recalbox and Rpi5. It would therefore be great if the gpiozero library could be added to Recalbox in one of the next updates so that the scripts can work with GPIOs again. If anyone has found a solution for GPIOs on an Rpi5, please let me know.
