Mapping pause function to game button

[Tailslide]

I see a way to map the pause feature to a keyboard press.. unfortunately my pause button is wired to a game button.

Is there some way to map pause to a joystick button or do I need to rewire my pause button?

Also, is there some way to display or speak the button mappings when paused?

I used to use gameex and it could blink the buttons and speak the commands for each button when paused.

Looks like if I map the mame pause key to my button it works and ledblinky reads the controls OK I just lose the fancy pause screen.
