[Solved] How to set joystick button to open config menu

[betara]

Hello PPSSPP friends,

I'm building a desktop pc to work only with PPSSPP as an arcade. The hardware is an i3 3.7GHz, 8G RAM, HD 1T 7200 RPM, HD Graphics 4400 1G Dedicated, Genuine Windows 7 Home Basic using the PS3 Controller with default settings.

The PPSSPP runs fine starting with windows as fullscreen and all my favorite games too, but there is one thing that its not so good. There is no away to set a button in my joystick to open the PPSSPP menu... I can do this only using the keyboard (ESC key).

In this way, will PPSSPP have the option to open menu using the joystick in the future? If yes, my PPSSPP arcade will be complete with no keyboard attached, using only the PS3 joystick.

Thank you.
