This is my Wii Light Gun that i created after looking at
Cyberpyrot's NES gun which i thought was so cool.... but as you can see i didn't want to modify the whole wiimote.
So as i thought about what i was going to do i decided to make a detachable cable that goes through the battery compartment and connect to the gun. And if your wondering the cover can still close with the cable in it..
this picture is mainly to see the detachable cable
this is while i was testing it on Resident Evil UC

Cyberpyrot for his NES gun tutorial
UPDATE 2
as i am going to finish this i have decided to paint it white and use the clear wii grip to keep it in place
