I assume you know that the game did come out for the Amiga computer. It looked almost identical to the TG-16 game. There were also several other baseball games that re-used assets from TV Sports Baseball; the PC version of Bo Jackson Baseball was one of them.
Which is because CinemaWare became Acme Interactive, which then became Malibu Interactive.
So the same folks worked on a lot of games and reused code and assets.
At one point, the Bo Jackson Baseball programmers were doing 2 different baseball games for 2 different publishers at exactly the same time (neither publisher knowing about the other).
