No add coin Player 1 with Picade HAT

Hi everyone.
Ive just started to bulid using the Picade HAT on my pi3 running Retropie.
I’ve installed the driver’s from get.pimoroni.com
But can’t get it to first turn on when powerd though the HAT. If I power the PI I can configure the joystick and 6 buttons and sound but can’t find where to add the Coin or Player 1 buttons.
I can start the MAME by using select to add coins and start for player one.
Sorry if there is already an answer on the forum my eyes are going and can’t get my text to voice to work properly (but that’s a post for another day)
Thanks as always
