maybe an evolution of Polaris etc.?

the stars scroll backwards when in cocktail mode, the direction changes when the screen
|
||||
is flipped but is still reversed compared to upright. We would have no way of knowing
|
||||
if we're in cocktail mode without checking the dipswitch, so I think this is a game bug
|
||||
furthermore the game seems to set what I believe to be the 'flipscreen' bit for player 2
|
||||
even when in 'upright' mode, so it's possible this romset was only really made for a
|
||||
cocktail table?
