How the heck do I get Zombie raid cross hairs to work?

[rrcade]

For now I'm just trying to get it to work with a mouse. When I start I get a blue cross hair and a red one that is offset from the blue, the blue seems to work with my mouse movement but the red that kind of follows it is the one that shoots. I hit f2 and tried calibrating it which seems to work until I reset the game then it's all screwed up again. I've tried hitting tab and playing with the analog settings, and I've also tried deleting the hi,nvram,etc files and starting over but nothing works. Could someone please give me a step by step explanation on how to get this working? I'ts mame 139
I really appreciate any help.

Added note, games like duckhunt and police trainer and deer hunter work fine with the mouse. I can't get Zombie raid or Carnevil to work though
