I only have one GunCon3 which came bundled with Time Crisis 4. Setting it up is a little annoying, as it requires a couple of sensors to be setup (similar to the Wii sensor bar), and it’s not very well supported unfortunately.
As far as I know, only TC4 and the Razing Storm collection support it. I hope I’m wrong though, let me know if I missed anything…
Thanks for the information! I may just leave it plugged in to avoid any trouble.
As far as the supported games go don’t believe you missed anything. Those are the only two I know of.
I have a friend who wanted to downsize his collection and is selling me his CIB Time Crisis 4. I’m looking forward to trying these game out. 
Would like to see impressions of the GunCon 4. I played TC4 and Razing Storm using the Playstation Move controllers, and always fgelt like the aiming was too sluggish for my tastes. Kinda like dragging a cursor around the screen.
