I'm looking at a 3 gun (positional) arcade game called Beast Busters that's in incredible shape. Since it's a stand-alone machine (and am not interested in making it a part of my MAME project), I'd really only be interested if I could get it to switch between that and other games that use a positional gun, like Operation Wolf and Operation Thunderbolt. However, Beast Busters is made by SNK and the Operation xx series are by Taito. I don't know anything about PCB interchangability, but I thought there might be a way to set up something to switch between boards? Or is that just not how it works? Thanks, and forgive my noobness.
