this 'pac90' bootleg has been showing up on boards pulled from actual arcade cabs in Spain as of late.

we know the origins of the set (was made by Mike Coates etc.) but it's pretty old now, and as it's showing up on real hardware that's been used in arcades I think we may as well support it.

61for inclusion in MAME.  However the roms with checksums are listed below to prevent it being added
62as a newly "found" game:
