Do u really need to have 2 buttons for the mouse buttons on your CP, can u not just use 2 of the Player 1 or player 2 buttons for mouse button 1 & 2?

Well I placed a set of track ball buttons on both my player one and player two controls. The top to buttons are the t-ball buttons. They also look like part of the players controls. I did this because there are both right and left handed ppl in my house. It also looks even.

I wired my player 1 and 2 buttons in parallel to my Opti-Pac and I-PAC. Not that intuitive to first time users, but works real well for me and keeps the panel less cluttered and nice and clean.

If you don't plan on playing other games besides mame that use the mouse buttons, then I don't see a need.  Even if you do, you could wire the mouse buttons to the first two buttons on player one or something like that.
