Hi. Hoping someone may be able to advise on this please. Such a simple problem but I really cant work out what's going wrong. I am using a single Sinden gun which works fine in MAME however in Teknoparrot I am trying to set it up with Aliens Extermination. In the Controller Setup option. I choose Player 1 Light Gun and set it to my Sinden. When I set Player 1 Trigger and press the trigger on my gun it keeps mapping to 'Sinden Lightgun Rightbutton' which is one of those on the side. If I press the right button that too registers as 'Sinden Lightgun Rightbutton'. Is anyone able to advise why the trigger will not set itself to trigger ? Game all works fine apart from this. 😞 Thanks
