Error: FBNEO does not run games with Light Gun

Hello everyone. I wanted to tell you that I can't run any game with a light gun with FBNEO. I get the error "object reference not set to an instance of an object". With the rest of the games everything works fine, only those with a light gun give me this problem. I hope someone can help me.

Hello,

This has been fixed in next version,
Do you have also a mouse plugged ?

And are you having issue with libretro:fbneo or fbneo standalone ?

Can you share here your emulatorlauncher.log file after running a game with this error ?
(Or a link to it on a drive)

Thanks for your reply. I'm using the latest version of Retrobat (6.3.0.), I use libretro:fbneo and I have a mouse connected. Here is the code:

Ok I see, will be fixed in next version, in the meantime you might want to set USE GUN to "NO" in advanced configuration, this might fix it.
Or disconnect one of your mice.

Thank you very much. I can play now. Setting the "USE GUN" to "NO" helped me.
