I'm adding extra buttons to my cab so that I won't need a keyboard, but I am not sure which buttons are totally necessary. Now the obvious answer to that is whichever I use, but I want to minimise the number of extra buttons.
For instance, some games have one credit chute while others use 2 or more. I will have as many games as possible set to free play so my question is, are there any games that cannot be set to free play that use more than one coin chute?
