Help to wiring GPIO and retropie

[krapazok]

Hello everybody !

I’m new on Retropie and is for me, the best solution !

I wish to create a new Arcade cabinet (my first cabinet’s running on a normal PC with MAME and USB adapter )
But i need to using only Raspberry.

BUT, i have search on the web and i haven’t found the solution of my problem.

For you, this solution is correct ?
and the same on the Raspberry Pi B+’s GPIO for make a two player panel ?

Thank you ! :)
