Marble Madness/Versions

Arcade
The arcade version provides trackballs to control the players. It may also provides the player an option to continue racing the other player if he dropped out.

Commodore Amiga
Ported by Electronic Arts, and can be run from Workbench.

Control orientation is rotated 45 degrees clockwise: a downward pull on the joystick or mouse results in the marble moving downward and to the left. In addition, the button on the controller may be held for a turbo boost.

NES
A reasonably accurate conversion that plays well, despite lacking a track ball controller. Players can choose between holding the control pad in a standard horizontal orientation, or rotated 45 degrees clockwise to make diagonal movement easier. The colors are not as vibrant as the arcade version, however.
