Thanks everyone, this is Awesome! I have my 40 pin wired up AND working properly.

Now for a couple of questions....
I have player 1 and 2 start, but no button for coin 1 and 2. How do I get MAME to 'accept' coins when the game starts?
Also, I remember seeing it somewhere, but can't find it, how to get around the 'OK' at the start of games?
Thanks for the help!
