mame help with config

hi when i enter mame options i have alot of things that i dont realy understand
there is some guide that show every option with details ? thanks

Why do you need to get into options? What are you looking to change ?

i want a key to delete the coins because in some games there is coins before i enter them

batodon1911 hm. not really sure. Are you planning to make people pay to play or something? ;-)

no but its not nice to have alot of coins
