impossible to map a Button for Esc (quit)

[Giandj]

Hi anyone can modify the Exit mapped on ESC key (default) with an Arcade Button (custom) to quit supermodel3 emulation ?
I have an Arcade Cabinet (based on PI5) but witout a phisical keyboard, seems impossible to quit a game without a keyboard.

Supermodel.ini can't instruct Supermodel3 to exit by a custom mapped button.

I think that Someone must modify Supermodel3 code (before make) , to map another button different to keyboard esc (escape).

Thankyou

; Common
InputUIExit = "JOY1_BUTTON10+JOY1_BUTTON9,KEY_ESCAPE"

On my supermodel3.ini it's this the default configuration.... joybutton9 + joybutton10 it's SELECT+START on arcade stick.
It's not WORKS. I have tryed to set a single button... can exit from supermodel only if i click EXIT on my keyboard.
