The hardwire jumper is a possibility with some companies doing it that way, but
after looking at sourcefile for a refresher and noticing a few of the game entries have cocktail table romsets, I am going with Vas take on this.

Judging by Japanese region Tranquilizer Gun flyer, Tranquilizer Gun may have been a dedicated upright cab and cocktail table with a rom or two being different between the Japanese region cab models. And any Tranquilizer Gun coinop hardware that might have been marketed/exported to N. America or other regions was an export kit update that was meant to fit inside/replace Borderline in Borderline cabs.

That's my guess with Tranquilizer Gun. Maybe someone emufriendly in Japan might be able to help out later and fill in the blanks with upright and cocktail table model rom sets? *wishful thinking*

As for Japanese region Tranquilizer Gun flyer, that is a flyer that is on want list of Flyer Fever. iirc System 16 web site had a link to a different flyer variation, but since that link no longer existed, Sixtoe removed that flyer link.

Sega N-Sub (upright)

As for N-Sub, while upright is emulated, there is also a cocktail table unit not yet emulated and the roms set layout is different between upright cab versus cocktail table model which will make the cocktail table unit a different rom set and also be a wanted rom set.
