I could have put this in a number of different categories, but I chose console. First with the caveats. Of the top of my head, I'm not sure what 4 player games are available via coinops lite 5. So to keep it simple I'll just ask about the console in general.
If I want to extend the player 3 and 4 controls from the inside to an external jack, what challenges am I faced with? Can I wire the control to a usb jack (neutech? neutrix?) and plug in a wired controller for the odd game that takes more than 2 players?
