Trying to get Demul Shooter working (aimtrak guns)

[ToxicTrev111]

hey guys, I am a noob to demul shooter. I am trying to get it working properly, first with sega model 2 emulation. I was trying to get it going with house of the dead last night, I had no luck. If I left the raw input = 0 in model 2 I could get the gun ( aimtrak ) to track , however when pulling the trigger it would only reload. If I pressed " z " on the keyboard it would fire. how can I fix this ? Also If i put model2 raw input = 1 , which from what I read is what I need to do for both guns to work, the gun would not track at all. any help is greatly appreciated .
