Judging from videos online, there are two versions of Basketball. One where
the display shows "12" at power-on(as on MAME), and one that shows "15".
There's also an other version of Hockey, presumably for the foreign market.
It plays more like Basketball/Soccer: no penalty boxes and you can't go
behind the goal.
