Hi there -
I appreciate the email, but in the future, please ask me questions in
the forum - so that other members of the Clockwork community can learn
as well. Just like you, I am a customer and do not have all the answers.
For the “Coin” button in MAME you can use the inbuilt settings in CPI
MAME
thread here:
In short: they say that you cannot really pick your own combination of
buttons, but have to select what is there in the menus of MAME. In my
own Clockwork I use the button “SELECT” to insert a coin in MAME
hope this helps -
CM
