Ahh, ok.  

Are you sure that I don't need 7 buttons per player for any games?

My button layout is like this:

x x x x
x x x

Should i make it:

1 2 3 4
4 5 6

or...

6 5 4 3
3 2 1

Thanks for the help!  As long as there are no games requiring 7 buttons I'll be fine.  I do want to hookup a dreamcast in the future, but I can wire two buttons to one terminal for the I-PAC, and then wire it as a unique button the dreamcast, right?

Thanks!

You have the following options:

1)  Wire the extra 2 buttons to the Opti-pac and set MAME up to use Mouse button 0 and Mouse Button 1 for the Admin functions.

2)  Combine button 7 as mentioned above.

3)  Wire the I-PAC to activate the shift function with a single button press - this can be done with a Resistor/Capacitor circuit.  Andy had a diagram somewhere on ultimarc.com, but I can't find it now.  I'm also not sure if you can wire more than one button this way.  You could E-mail Andy about it, if this interests you, though.

you also dont nessesarily need 4 admin buttons.  Most of the admit features can be shift input with combinations of player1 button and joystick.

Right, but he already made the overlay to support them.  (White-out has no place on an arcade cab!)

Good point
