Hi to all i'm building a 4 player CP with  7 button for 1-2 player and 4 for 3-4 player plus pause and esc.
I'm interested in KeyWiz40-ST  but it has only 40 direct input while i've to use 50 direct input.
There is a way to configure it or i've to buy ipac4 (i prefer KeyWiz40) ?

Thanks a lot

4 joysticks: 16 inputs
22 buttons: 22 inputs
Esc + Pause: 2 inputs
                  =40 inputs

How about running p1 and p2s buttons (5,6,7) to p3 and p4 (2,3,4) in parallel but having a switch control the ground, basically you would flip a switch and it would "give" the buttons to p3&4.

I don't really know if that made any sense but I've done the same thing on my CP, but using 2 joysticks and switching between them.

Basically its more of just a config in MAME.

A switched ground is also really good to keep little kids from actually pressing any buttons when "playing" next to you.
