Thanks for your replies.
CPO is male....so "muy bueno"

I believed advisable to place small buttons to control the internal options of mame (escape button, reset,pause, exit, config.)
Is much more useful, besides to save space in the panel.
The central stick exclusively is dedicated for 4 way games.
And the cofiguration of the buttons of each player is a disposition for games of 6 buttons (capcom layout) and 4 buttons(snk layout)
There are 2 buttons on each side, left/right flippers and left/right shock.....(maybe i will put another one on the right side for the center shock!!)
And one button on the front panel (the yellow one) for launch the ball on the Visual Pinball emulator.
The connections are mappes as it shows:

Kind regards.
