Just burned "joker.bin" from "norautp" to an eprom and tried it in my noraut cabinet. it plays the same on the cabinet as it does in mame 

It plays fine if you change dip2 to ON. 
But this sets the machine to hopper mode to pay out coins.

If you set dip2 to Off it puts it into credit mode and thats when the problems appear.

I noticed if you press half gamble once and release it one credit is taken and Low is somehow pressed but if you hold down half gamble it clocks down one credit at a time and will go to zero credits if you continue holding it
 
the game will continue as normal when you release the button because you have no credits left to bet, But the next time you get a win Low is pressed as soon as you go into the gamble screen. this is not normal 

Prog.bin from "norautpn" works fine on the cabinet when burned to eprom.
