i am using emulatorstation on my carbinet based on a Pi2.
My joysticks and my buttons are conneted on a kind of usb-keyboard.
In all Retroarch emulators you can use the “-” key and the ‘+’ key of keyboard to control the volume in game.
Additionally i use the gngeo-pi emulator (one of my favourite:)). Unfortunately i find no way to control the volume.
Is there any way (for example in the ~./.gngeo/gngeorc) to define the ‘-‘ and ‘+’ key in order to control the volume?
It could be better for my relationship if i can set the volume down 🙂
if you know what i mean 🙂
