[Q] Physical Key support & button setting

[xsacha]

Hi guys, i have a little problem, with PPSSPP missing a "quit" or "back" button from ingame, because my phone Nokia N8 doesn't have a going back button like on android hope you find o way in the next update to add a button THX, in rest the emulator works fine and tried "pinball fantasies" and work's like a charm.

The back arrow is at the top center of screen.
