 It seems an easy fix.... change the PORT_VBLANK from IP_ACTIVE_HIGH to IP_ACTIVE_LOW.

 no.

PORT_VBLANK lost support for multiple bits, I assume Aaron will fix it.

this should work but doesnt:
    PORT_BIT( 0x00f0, IP_ACTIVE_HIGH, IPT_CUSTOM ) PORT_VBLANK("screen") // all bits? check..

changing it to this fixes the problem:
    PORT_BIT( 0x0010, IP_ACTIVE_HIGH, IPT_CUSTOM ) PORT_VBLANK("screen") // all bits? check..
    PORT_BIT( 0x0020, IP_ACTIVE_HIGH, IPT_CUSTOM ) PORT_VBLANK("screen")
    PORT_BIT( 0x0040, IP_ACTIVE_HIGH, IPT_CUSTOM ) PORT_VBLANK("screen")
    PORT_BIT( 0x0080, IP_ACTIVE_HIGH, IPT_CUSTOM ) PORT_VBLANK("screen")

 Other than copsnrob.c and this driver, others are affected too.
These are users of multiple bits on PORT_VBLANK (my eyes may have missed one or two):

File bwing.c
File copsnrob.c
File dassault.c
File dgpix.c
File hng64.c
File liberate.c
File simpl156.c
