Im using FCE and it works fine (duck hunt ect), also fine playing HOD3 and silent scope. I am using the Boss battle light guns.

as for xsnes9x i cant get any games to use the light gun at all.

There is a "configure light gun" option, but no way the gun can actually be configured.. the screen registers the gun, but i can't change the screen mode or "calibrate" as it says, by pushing the X button.. nor can i "change resolution" by pressing Y..

has anyone found a solution to this? or knows if there is an issue?

I searched already and found similar problem, but no solution.

Thanks in advance

I had the same problem, but after I plugged the gun in to controller port 2 it detected it. Now I have the problem of 1/4 of the screen (rigth hand side) does not detect the gun. Weird, but I've heard so similar problems with no fix : ( Apparently a new tv 'could' fix it. Yet to try lol

I had the same problem with xSnes9x. The lightgun will work in the games, but I couldn't configure it.

However,

You'll have no problems with Lightgun configuration, use, lightgun force feedback, on screen crosshair, etc... in ZsnexBox. You can even play lightgun games without the lightgun via the Xbox controller. And all of this works in 480i, 480p, 720p, and 1080i.
