@escc1986 Hi,
I'm in the same situation as you... I would love to play games like Time Crisis with my DolphinBar and my Wiimote as "the Light Gun" in the DIY Arcade machine that I'm currently building, but... PCSX-Rearmed doesn't detect my Wiimote as "the Light Gun"... Only recognizes standard controls, nothing more... It's very frustrating...
Hope someone could do a simple and easy to follow tutorial on how to make the Light Guns to work with this core, and also make sure that all of the other games still work the same as they do right now with the unmodified core already available from the RetroPie Setup.
Hope that this topic gets more atention.
