yeah, i have some of the PS2 guns (namco guncon 2) connected via the green component video cable, and i was able to get them working, but i really would like to use a real arcade gun. when i bought my empty showcase cabinet a few years ago, it came with a happ gun, that has just been collecting dust in my basement. i'd love to put it to good use. I'm afraid to let my kids use the guncons because i'm sure they'll break them.
