Notes:
- Speed Basketball only has some LEDs and lamps, the rest is mechanical.
Video: https://www.youtube.com/watch?v=efs2KNNncn8
- Speed Soccer / Speed Shot is on the same hardware
- The driver contains the ROMs for the sound PCB of Exciting Boat Race as a placeholder, since it's the same PCB as the one used by Speed Basketball.
Exciting Boat Race is a main + satellites arrangement with video, so when the other PCBs are found it should be moved out of here.
