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 . 
Thanks.
