Hi All! I am new to this site and have a love for my 70s.80s games as everyone on here. I built a Pong dedicated cab and have nothing but Pong games/ Ping Pong etc. I was able to get Ultimate Pong to work and mapped using 2x spinners. The problem is I cant find the mapping to launch the ball in any of the games in UP. I have went through every bit of the Mame menu and can not find a fire/start/etc way of launching the ball to start the game. If anyone on here has got this to work please advise, I would greatly appreciated it.
