F1 Grand Prix Star II
Jaleco, 199?

This game uses the same bottom and middle boards as Grand Prix Star, however the top board 
(sound + I/O) is different (though I guess it has the same purpose.)
The game is mostly a simple ROM swap on a F1 Grand Prix Star board. 
The swapped ROMs have been factory socketed. Some ROMs are soldered-in and match some in the
F1 Grand Prix Star archive (i.e. they are not swapped).
