I also want to take a minute to talk about the guns. I use 8-pin GX16 sockets for the lightgun ports. Again, not too much detail since there is a lightgun forum, but I just wanted to show how the cabinet is connected.
It has 4 ports total, supporting up to 4 players. Then, there are dual power buttons to disable the recoil if desired. Each power button affects 2 ports. So the left side as 2 sockets + 1 power button, and the same for the right side.
My cabinet software will do a bunch of calculations to determine which lightgun should be used for each player. For example, if there is just 1 gun plugged in and it's on ports 3 or 4, then I assign it to player 2 because it's plugged into the right side of the cabinet. If the game happens to only support 1 player, then I assign it to player 1. If the game is a 4-player game and a gun is plugged into port 3, then it is assigned to player #3.
I configure the gun per game and handle outputs (i.e. replacing mamehook).
The GX16 sockets are connected are a combined USB2.0, and then 12+24v pins added. This will allow me to create lightguns that have a 12v or 24v recoil, without the need to plug them in separately. So the 12v guns will use the 12v points, and the 24v gun will use the 24v pins. Just plug an play.
