Sadly, the Bradley trainer doesn't actually work properly in MAME, because the mathbox (a math accelerator circuit) in the Bradley Trainer used custom PROMs which differ from the stock Battlezone (implementing several more commands than 'stock' Battlezone does), and these were never dumped by Scott Evans.

Hence the "AI" (and collision detection?) doesn't work correctly.
