Japanese-language flyers show an upright cabinet with a start button, steering

wheel and a control lever marked LOW at the upper end of the range and HIGH at

the lower end. It appears to be spring-returned to the LOW position. The

TODO:

- unknown DIP switches, and verify factory defaults;
|

- verify DIP switches factory defaults (not mentioned in Japanese manual);
|
||||
- several unknowns in the video emulation:
|
||||
- score layer is a simplification hack, it is unknown how it should really
|
||||
cope RMW-wise against main layer. It also has wrong colors (different color
|
||||
base or overlay artwork, with extra bit output for taking priority?).
|
||||
The score background color should change from white(or is it cyan?) to red
|
||||
after Extended Play, the score digits themselves should always be black;
|

cope RMW-wise against main layer;
|
||||
- According to flyers, screen sides should have a green background color,
|

it can't be an artwork overlay since it only occurs when the trees are
|

on screen. However, the German flyer contains a cabinet photo and there
