I'm finishing up my vigolix Mame cabinet from last year...I have mini pac hooked up to 2 joysticks and 8 buttons each side.  I purchased the minipac thinking it was hook things up and they would just work.  But I'm finding out it's more difficult then that.  
When I hooked up my 1 player button all the sudden my down joystick move would bring up the options menu.  Any help?
Thanks in advance....
