How to exit ppsspp with controller ?

[Arkoth79]

Hello,

I try Portable-Game-Station with ppsspp (psp). I works (very good).

But, how can I exit the emulator ppsspp with my controller ? (controller was configured on the first launch, it's a nvidia shield controller gen2 on my pc on usb)

Is there a config file to edit to do this ?

Thanks for your answer.
